(Received 26 August 2011; accepted 1 September 2011; online 14 September 2011)

The Sm atom in the cation of the title salt, {[Sm(NO₃)₂(C₆H₁₈N₃OP)₄][AgS₄W]}_n, is coordinated by eight O atoms derived from two chelating nitrate anions, and four hexamethylphosphoramide ligand, defining a distorted square-antiprismatic geometry. The anions self-assemble into polymeric chains via W—S—Ag bridges having a [AgS₄W] repeat unit; the W—Ag—W and Ag—W—Ag angles are 161.657 (17) and 153.978 (9)°, respectively. The title complex is isostructural with the Y, Yb, Eu, Nd, La and Dy isomorphs.

Comment top

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

The title complex is isostructural with Y (Zhang, Cao et al., 2007; Zhang, 2011), Yb (Cao et al., 2007), Eu (Zhang, Qian et al., 2007), Nd (Tang, Zhang & Zhang, 2008), La (Tang, Zhang, Zhang & Lu, 2008) and Dy (Zhang, 2010) isomorphs. The Sm atom 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 161.657 (17) and 153.978 (9) °, 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 stirring for two minute, then 0.5 mmol Sm(NO₃)₃.6H₂O was added. After filtration the orange filtrate was carefully laid on the surface with 12 ml i-PrOH. Orange block crystals were obtained after about one week.

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.
