{[Na1(μ-H2O)Na2]2[(C2O4)2Cr(μ-OH)2Cr(C2O4)2]·H2O}n, a novel hydrated form

Abstract

The unit cell of the title compound, poly[[μ-aqua-μ-hydroxido-di-μ-oxalato-chromium(III)disodium] monohydrate], {[CrNa2(C2O4)2(OH)(H2O)]·H2O}n, contains four [Na1(μ-H2O)Na2][(C2O4)2Cr(μ-OH)·H2O] formula units, each of which consists of two crystallographically independent Na+ sites (bridged by one aqua ligand), one half of a centrosymmetric di-μ-hydroxido-bis­[cis-bis­(oxalato)chromate(III)] dimer, [(C2O4)2Cr(μ-OH)2Cr(C2O4)2]4−, and one uncoordin­ated water mol­ecule. The structure is best described as a coordination polymer in which the three-dimensional lattice framework is realized by the inter­connection of the metallic atoms via the O atoms of the aqua, hydroxide and oxalate ligands. One Na atom is hepta­coordinated by one water, one hydroxide and five oxalate O atoms, whilst the other is penta­coordinated by one water and four oxalate O atoms. The coordination around the Cr3+ sites is pseudo-octa­hedral, involving four aqua and two hydroxide O atoms. Adjacent Na atoms are separated by 3.593 (2) Å, whereas the intra­dimer Cr(...)Cr spacing is 2.978 (1) Å. The crystal structure is consolidated by extended relatively weak O—H(...)O hydrogen bonding with O(...)O distances ranging from 2.808 (4) to 3.276 (5) Å.

Comment

Scaringe et al. (1977) have previously studied the system Na4[Cr(ox)2OH]2.6H2O (ox = C2O42-), paying special attention to its structural-magnetic correlations. We report herein compound (I) as a novel hydrated form of this system, which involves a different number of water molecules and exhibits a different mode of coordinative polymerization.

Fig. 1 depicts the centrosymmetric anionic dimer, [(C2O4)2Cr(µ-OH)2Cr(C2O4)2]4-, which constitutes the main structural motif of (I). It is virtually identical to the motif reported previously (Scaringe et al.,1977), as revealed by the closely comparable geometric parameters (Table 1). A larger portion of the structure of (I) is shown in Fig. 2, highlighting heptacoordination of Na1, pentacoordination of Na2 by O atoms, and the bridging of these metallic sites by an aqua ligand (O10). The oxygen atom, O11, is seen to be part of a water molecule of crystallization.

Beyond their identical P21/c space group, the two structures present a number of differing features. The crystal data of (I) compare with the reported values (in square brackets) as follows: a = 9.478 (1) [19.530 (12)] Å; b = 8.603 (1) [9.860 (7)] Å; c = 12.535 (1) [12.657 (10)] Å; β= 102.50 [106.93]°; Rfinal = 4.4 [6.1] %; Z = 4 [4]; Dx = 2.177 [1.966] Mgm3-; T(K) = 173 [293]. The asymmetric unit of the reported structure contains six H2O molecules and four crystallographically independent Na+ sites, whereby Na1 and Na3 are bridged by the aqua oxygen atom, WO(2), and Na2 and Na4 by the aqua oxygen atom, WO(1), with each Na+ site assuming coordination number 6. The asymmetric unit of (I), by contrast, contains four Na+ ions (located at two crystallographically independent sites) and four H2O molecules. Note, furthermore, that coordination numbers 5 and 6 by O atoms have been frequently reported in the literature (Scaringe et al., 1977; Ferreira et al., 2001; Köse et al., 2009), but coordination number 7, if any, is rather scarce for Na+. Like in the reported material, the bulk structure of (I) is consolidated by O—H···O bridgings which are, however, stronger in the former than in the latter case (Table 2).

Preliminary observations from our laboratory promisingly suggest that a well conceived and systematically conducted preparative procedure may be applied generally to fabricate a whole range of homologous magnetic materials, provided appropriate paramagnetic transition metal centers are involved.

Experimental

Go In an initial attempt to prepare the targeted material of empirical formula [Ba2(H2O)6][Cr2(OH)2(C2O4)4].H2O, compound (I), instead, was obtained as follows: Cr(NO3)3.9H2O (4.0 g, 10 mmol, Riedel-de Haën, pure) was dissolved at room temperature in H2O (150 ml) and filtered. H2C2O4.2H2O (2.6 g, 20 mmol, Riedel-de Haën, 99.5–100.5%) was dissolved therein. This solution was added dropwise to a suspension of Na2CO3 (1.6 g, 15 mmol, Riedel-de Haën, 99%) and Ba(OH)2.8H2O (3.2 g, 10 mmol, Merck, p.a.) in 200 ml of water, and stirred overnight at ca 70 °C. The violet mass that had formed was filtered off, washed twice with 15 ml H2O and dried between filter papers. A second crop of material was obtained by concentrating the mother liquor to a volume of ca 20 ml, washing the material twice with 5 ml H2O and drying it as above. Recrystallization from oversaturated aqueous solution yielded prismatic violet crystals appropriate for X-ray diffractions.

Refinement

The water hydrogen atoms were located from a difference Fourier map and refined isotropically, with the O–H distance restrained to 0.88 (4) Å, Uiso = 1.5Ueq (O). Other H atoms, for the OH group, were constrained to ideal geometries, with 0.85 Å.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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.
