Undeca­europium hexa­zinc dodeca­arsenide

Abstract

The title compound, Eu11Zn6As12, crystallizes with the Sr11Cd6Sb12 structure type (Pearson’s symbol mC58). The complex monoclinic structure of the first arsenide to form with this type features chains made of corner-sharing ZnAs4 tetra­hedra, separated by Eu atoms. There are a total of 15 unique positions in the asymmetric unit. Except for one Eu atom with site symmetry 2/m, all atoms are located on mirror planes. An usual aspect of the structure are some Zn—As distances, which are much longer than the sum of the covalent radii, indicating weaker inter­actions.

Related literature

The growing inter­est in ternary pnictides of alkaline- and rare-earth metals with group 12 metals has feen fueled by the recent discovery of superconductivity (Rotter et al., 2008 [triangle]). Such compounds have also been investigated because of their promising behaviour as materials with high thermoelectric conversion efficiency (Snyder & Toberer, 2008 [triangle]). Our own exploratory studies revealed a wealth of new compounds with diverse crystal structures, including Ca2CdSb2 and Yb2CdSb2 (Xia & Bobev, 2007a [triangle]), A 9Cd4+ xPn 9 and A 9Zn4+ xPn 9 (A = Ca, Sr, Eu, Yb; Pn = Sb, Bi) (Xia & Bobev, 2007b [triangle]), A 11Cd6Sb12 (A = Sr, Ba, Eu) and Eu11Zn6Sb12 (Park & Kim, 2004 [triangle]; Xia & Bobev, 2008b [triangle]; Saparov et al., 2008a [triangle]), A 21Cd4 Pn 18 (A = Sr, Ba, Eu; Pn = Sb, Bi) (Xia & Bobev, 2008a [triangle]), Ba3Cd2Sb4 (Saparov et al., 2008b [triangle]), Ba2Cd2 Pn 3 (Pn = As, Sb) (Saparov et al., 2010 [triangle]). The title compound is the As-analog of Eu11Zn6Sb12 (Saparov et al., 2008a [triangle]). For covalent radii, see: Pauling (1960 [triangle]).

Comment

The structure of Eu11Zn6As12 projected along b-axis is shown in Figure 1. The asymmetric unit is composed of 6 Eu, 3 Zn and 6 As atoms, all in special positions (Wyckoff position for Eu6 is 2a, for all others 4i).

The anionic substructure is made of Zn-centered ZnAs4 tetrahedra that share common corners to form chains. The terminal As atoms of two chains are close together, so that they form a covalent bond. This can be inferred from the resulting As5—As5 distance at 2.457 (3) Å, which is on par with the As—As separation in elemental As (2.517 Å). All other interatomic distances fall within the expected range, excluding the Zn3—As5 distance at 3.288 Å. The latter is too long - more than 30% longer than the sum of the Pauling's covalent radii (Pauling, 1960) - to be considered a simple 2-center-2-electron bond. Analogously longer than normal Cd3—Sb5 and Zn3—Sb5 distances have been reported in Eu11Cd6Sb12 and Eu11Zn6Sb12 (Saparov et al., 2008a). We refer to the theoretical studies on Sr11Cd6Sb12 and Ba11Cd6Sb12 (Xia & Bobev, 2008b) for a more detailed discussion of the bonding interactions in this structure type.

d-metal centered tetrahedra of the pnicogen elements are recurring motifs in the structural chemistry of such solid-state compounds, as evidenced by a number of reports (Rotter et al., 2008; Snyder & Toberer, 2008; Xia & Bobev, 2008a; Saparov et al., 2008b; Saparov et al., 2010). Sr11Cd6Sb12, the first structurally characterized phase with this monoclinic structure, was synthesized from a high temperature reaction of elements using Sn as metal flux (Park & Kim, 2004). In this report, the crystal structure was described as being composed of "double pentagonal tubes". A slightly different description of the structure was given in the light of the very long Cd3—Sb5 bond in Ba11Cd6Sb12 (Xia & Bobev, 2008b). Therein, the authors performed comprehensive electronic structure calculations aimed at full understanding of the bonding in Sr11Cd6Sb12 and Ba11Cd6Sb12. From these computational results, and from earlier results pertaining to related materials such as Yb2CdSb2 (Xia & Bobev, 2007a), A9Cd4+xPn9 and A9Zn4+xPn9 (A=Ca, Sr, Eu, Yb; Pn= Sb, Bi) (Xia & Bobev, 2007b), it can be expected that the Eu cations in Eu11Zn6As12 will be divalent, and the spins of the Eu's 7 unpaired electrons may couple magnetically at low temperatures. We were unable to experimentally confirm this conjecture because the title compound was not isolated as a pure phase, but magnetic property measurements on the isotypic europium antimonides Eu11Cd6Sb12 and Eu11Zn6Sb12 (Saparov et al., 2008a) confirmed Eu2+ cations (4f7 state). These measurements also suggested antiferromagnetic ordering in Eu11Cd6Sb12 below TN=7.5 K. The temperature dependent electrical resistivity measurements carried out on a single crystal of Eu11Cd6Sb12 suggested poorly metallic behavior, as expected from band structure calculations performed for Sr11Cd6Sb12 and Ba11Cd6Sb12 (Xia & Bobev, 2008b).

Experimental

The starting materials, Eu, Zn, As, and Pb, with stated purity greater than 99.9%, were purchased from Alfa or Aldrich, and used as received. Elements were loaded into an alumina crucible in a Eu:Zn:As:Pb=2:1:2:10 molar ratio inside an argon-filled glove-box. The alumina crucible was then sealed under vacuum in a silica tube. The reaction mixture was heated to 1223 K, kept at this temperature for 20 hours, and then slowly cooled to 723 K at a rate of 3 K/hour. Finally, the Pb-flux was removed by centrifugation at this temperature. Together with irregular-shaped crystals with hitherto unknown structure, black needle shaped crystals of Eu11Zn6As12 were also obtained.

Refinement

The collected data were successfully refined using the coordinates of Eu11Zn6Sb12 (Saparov et al., 2008a) as a starting model. The maximum peak and deepest hole are located 0.97 Å away from Eu6 and 1.47 Å away from Zn1, respectively.

Special details

Experimental. Selected in the glove box, crystals were put in a Paratone N oil and cut to the desired dimensions. The chosen crystal was mounted on a tip of a glass fiber and quickly transferred onto the goniometer. The crystal was kept under a cold nitrogen stream to protect from the ambient air and moisture.Data collection is performed with four batch runs at [var phi] = 0.00 ° (600 frames), at [var phi] = 90.00 ° (600 frames), at [var phi] = 180.00 ° (600 frames), and at [var phi] = 270.00 (600 frames). Frame width = 0.30 \& in ω. Data are merged and treated with multi-scan absorption corrections.
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
