catena-Poly[[tetra­kis(hexa­methyl­phos­pho­ramide-κO)bis­(nitrato-κ2 O,O′)neodymium(III)] [silver(I)-di-μ2-sulfido-tungsten(VI)-di-μ2-sulfido]]

Abstract

In the title compound, {[Nd(NO3)2(C6H18N3OP)4][AgWS4]}n, the central Nd atom of the monovalent cation is coordinated by eight O atoms from two nitrate and four hexa­methyl­phospho­ramide ligands. The monovalent anion, {[WS4Ag]}n, forms a polymeric chain in a distorted linear configuration with W—Ag—W and Ag—W—Ag angles of 163.81 (3) and 154.786 (12)°, respectively. Thirteen C and three N atoms are disordered equally over two positions. One C atom is disordered over two positions with site occupancy factors of 0.6 and 0.4.

Comment

One-dimensional Mo(W)/S/Ag anionic polymers have attracted much attention for their configurational isomerism (Niu et al., 2004, and references therein) and potential applications, especially in third-order nonlinear optical (NLO) materials. (Zhang, Song et al., 2007). Different solvent-coordinated rare-earth cations proved effective to obtain various configurations of anionic chains (Niu et al., 2004, and references therein). The title compound, {[Nd(hmp)4(NO3)2][WS4Ag]}n (hmp = hexamethylphosphoramide) with a wave-like anionic chain was prepared by following such route using Nd(III)-hmp complex as counterion.

In possession of two nitrate ligands, the cation in the title compound is univalent (Fig. 1), which leads to an anionic chain with a univalent repeat unit, unlike other solvent-coordinated rare-earth cations, in the literature (Niu et al., 2004, and references therein), which are trivalent and induce trivalent repeat units. For example, [Nd(dmf)8]3+ induces an anionic chain with a trivalent repeat unit [W4S16Ag5]3- (Huang et al., 1996).

As illustrated in Fig. 2, the anionic chain in the title compound has a distorted linear configuration with W—Ag—W and Ag—W—Ag angles of 163.81 (3) and 154.786 (12) °, respectively, unlike those in {(γ-MePyH)[WS4Ag]}n (Lang et al. 1993) and {[NH3C(CH2OH)3][WS4Ag](2DMF)}n (Huang et al., 1997), showing an ideal linear chain and a nearly linear chain, respectively. This observation suggests that cations with bigger bulk lead to more distorted anionic chains.

Similar angles for W—Ag—W and Ag—W—Ag are found in two distorted linear chains in {[Eu(hmp)4(NO3)2][WS4Ag]}n (Zhang, Qian et al., 2007) and {[Y(hmp)4(NO3)2][WS4Ag]}n (Zhang, Cao et al., 2007), implying that different rare earth cations with the same coordination environments will result in the same anionic structures.

Experimental

Ag2S (0.25 g, 1 mmol) was added to a solution of (NH4)2WS4 (0.70 g, 2 mmol in 30 ml h mp) with thorough stirring for 10 h. The solution underwent an additional stir for one minute after Nd(NO3)36H2O (0.44 g, 1 mmol) was added. After filtration the orange-red filtrate was carefully laid on the surface with 30 ml i-PrOH. Orange-red block crystals were obtained after ten days. Yield: 1.129 g in pure form, 40.2% (based on W).

Refinement

H atoms were positioned geometrically and allowed in the refinements in a riding mode, with C—H bonds = 0.98 Å and Uiso = 1.5 times the Ueq of the parent C-atoms. Parts of dimethylamine groups from hmp ligands have large librations, resulting in some disordered C and N atoms. The occupancy factors for C19 and C19' were allowed to be 0.6 and 0.4, respectvely, and for the rest of the disordered atoms 0.5 and 0.5. The disordered non-hydrogen atoms (C1,C3,C5,C9,C10,C11, C12,C17,C19,C20,C21,C22,C23,C24,N10,N11,N12,) were allowed isotropic displacement parameters.

Special details

Experimental. Analysis: calculated for C24H72AgN14NdO10P4S4W: C 20.52, H 5.16, N 13.96%; found: C 20.50, H 5.14, N 14.01%. IR: ν, cm-1, 478.5 m, 446.8 s (W-µ2-S).
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.
