(Received 17 September 2008; accepted 11 October 2008; online 18 October 2008)

In the polymeric title compound, {[Cu3W2(CN)16(C4H4N2)2(C6H4N2)2(H2O)2]·2H2O}n, the coordination geometry of W is an eight-coordinated bicapped trigonal prism. Five of the CN groups of [W(CN)8] are bridged to Cu ions. The coordination geometries of the Cu atoms are each pseudo-octa­hedral; one Cu atom is located on a centre of inversion. The cyano-bridged W–Cu layers are linked by Cu-containing pillars, to form a three-dimensional network with cavities occupied by noncoordinated water and 4-cyano­pyridine mol­ecules.

The preparation of ferromagnetic nanoporous materials is an attractive contemporary research area. An octacyanometalate [M(CN)8] (M = Mo, W, Nb)-based magnets are good candidates because of their high Curie temperatures (Garde et al., 1999; Zhong et al., 2000; Pilkington & Decurtins, 2000), functionalities such as photomagnetism (Arimoto et al., 2003; Catala et al., 2005; Ohkoshi et al., 2006,2008) and chemically sensitive magnetism (Ohkoshi et al., 2007). Octacyanometalates, [M(CN)8]n-, a versatile class of building blocks, can adopt different spatial configurations depending on the coordinating ligands, e.g., square antiprismic (D4h), dodecahedral (D2d), and bicapped trigonal prismic (C2v) (Leipoldt et al., 1994). In the case of Cu—W systems, several octacyanometalate-based magnets such as {[Cu3[W(CN)8]2]3.4H2O}n (3-dimensional network complex, 3-D) (Garde et al., 1999), {[Cu3[W(CN)8]2(pyrimidine)2]8H2O}n (3-D) (Ohkoshi et al., 2007), {[Cu3[W(CN)8]2(3-cyanopyridine)6]4H2O}n (2-D array), and {[Cu3[W(CN)8]2(4-cyanopyridine)6]8H2O}n (2-D array) (Ohkoshi et al., 2003), have been reported.

The asymmetric unit of the present compound (I) comprises a [W(CN)8]3- anion, a one-half of [Cu1(H2O)2]2+ cation (the Cu centre is located on a centre of inversion), a [Cu2(pyrimidine)(4-cyanopyridine)]2+ cation, and a water molecule, Fig. 1. The coordination geometry of W is eight-coordinated bicapped trigonal prismic, where five CN groups of [W(CN)8] are bridged to Cu ions (one Cu1 and four Cu2), and the other three CN groups are free (Fig. 2a). The coordination geometries of the two types of CuII ions (Cu1 and Cu2) are pseudo-octahedral. The Cu1 atom is coordinated to two N atoms of CN ligands, two N atoms of pyrimidine molecules, and two O atoms of H2O molecules. The Cu2 atom is coordinated to four N atoms of CN ligands, one N atom of a pyrimidine molecule, and one N atom of a 4-cyanopyridine molecule.

The cyano-bridged-Cu2—W layers are linked by Cu1 pillar unit (Figs 2b and 2c). This arrangement leads to the formation of cavities along a axis which are occupied by 4-cyanopyridine molecules and zeolitic-like water molecules (Fig. 2b). The 4-cyanopyridine molecules are aligned alternately without forming significant intermolecular interaction, Fig. 2c.

The field-cooled magnetization (FCM) curve at 10 Oe showed a spontaneous magnetization with a Curie temperature (Tc) of 12 K, the coercive field (Hc) of 70 Oe at 2 K, and, the saturation magnetization (Ms) value of 3.1 µB. This Ms value indicates that this compound is a ferrimagnet in which WV (S = 1/2) and CuII (S = 1/2, Cu2) in the layer are ferromagnetically coupled and WV and the bridged CuII (S = 1/2, Cu1) are antiferromagnetically coupled.

Experimental top

The title compound was prepared by reacting an aqueous solution of Cs3[W(CN)8]2H2O (1.2 × 10 -2 mol dm-3) with a mixed aqueous solution of CuCl2.2H2O (1.8 × 10 -2 mol dm-3), 4-cyanopyridine (1.8 × 10 -2 mol dm-3) and pyrimidine (1.2 × 10 -2 mol dm-3) at room temperature. The prepared compound was a green plate-like crystal. Elemental analysis found: C 30.36, H 1.88, N 23.99, Cu 13.84, W 26.20; C36H24N24O4Cu3W2 requires: Cu, 13.47; W, 25.98; C, 30.56; H, 1.71; N, 23.76.

In the IR spectrum, cyano stretching peaks were observed at 2154, 2162, 2170, and 2200 cm-1. The UV-visible reflectance spectrum showed absorption bands at around 700 and 1070 nm.

Refinement top

The H atoms of the solvent water molecules and the coordinated water molecules could not be located reliably and were not included in the refinement. The remaining H atoms were placed in calculated positions and refined using a riding model, with C-H = 0.95 Å, and with Uiso(H) = 1.2 Ueq(C). The maximum and minimum residual electron density peaks were located 0.66 and 1.61 Å, respectively from the W atom.

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 σ(F2) is used only for calculating R-factor (gt).
