(Received 29 November 2012; accepted 6 December 2012; online 12 December 2012)

In the title compound, {[Er(NO3)2(C6H18N3OP)4][AgWS4]}n, the polymeric anionic chain {[AgWS4]−}n extends along [001]. The ErIII atom in the cation is coordinated by eight O atoms from two bidentate nitrate anions and four hexa­methyl­phospho­ramide ligands in a distorted square-anti­prismatic geometry. Together with the two nitrate ligands, the cation is monovalent, which leads to the anionic chain having a [WS4Ag] repeat unit. The polymeric anionic chain has a distorted linear configuration, with W—Ag—W and Ag—W—Ag angles of 161.37 (2) and 153.548 (12)°, respectively. The title complex is isotypic with the Y, Yb, Eu, Nd, La, Dy, Sm, Lu and Tb analogues.

Comment top

One-dimensional Mo(W)/S/Ag anionic polymers have attracted much attention for their configurational isomerism (Niu et al., 2004; Zhang, Meng et al., 2010) and unique properties as functional materials, such as 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). The title compound, {[Er(hmp)4(NO3)2][WS4Ag]}n (hmp = hexamethylphosphoramide) with a wave-like anionic chain, was prepared by following such route using Er(III)-hmp complex as counterion.

The title complex is isostructural with Y (Zhang, Cao et al., 2007; Zhang, 2011a), Yb (Cao et al., 2007), Eu (Zhang, Qian et al., 2007), Nd (Tang, Zhang & Zhang, 2008), La (Tang, Zhang, Zhang & Lu, 2008), Dy (Zhang, 2010), Sm (Zhang, 2011b), Lu (Zhang, 2012a) and Tb (Zhang, 2012b) isomorphs. ErIII in the cation is coordinated by eight O atoms from two nitrate and four hmp ligands. 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. 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 161.37 (2) and 153.548 (12)°, respectively.

Experimental top

1 mmol AgI was added to a solution of [NH4]2WS4 (1 mmol in 10 ml hmp) with thorough stirring for 30 minutes. The solution underwent an additional stir for two minute after 0.5 mmol Er(NO3)3.6H2O was added. After filtration the orange filtrate was carefully laid on the surface with 15 ml i-PrOH. Orange block crystals were obtained after about one week.

Refinement top

H atoms were positioned geometrically and refined with riding model, with Uiso = 1.5Ueq(C) and 0.96 Å for C—H bonds.

Special details top

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.
