4,4'-Diazenediyldipyridinium 4-(4-pyridyldiazenyl)pyridinium octacyanidotungstate(V) dihydrate

S.-Y. Qian, W.-Y. Liu and A.-H. Yuan

Abstract top

The asymmetric unit of the title complex, (C10H10N4)(C10H9N4)[W(CN)8]·2H2O, contains two 4,4'-diazenediyldipyridinium, [H2(4,4'-azpy)]2+, two 4-(4-pyridyldiazenyl)pyridinium, [H(4,4'-azpy)]+, cations, two [WV(CN)8]3- anions, and four uncoordinated water molecules. Each of the W centers is coordinated by eight CN groups in a slightly distorted square-antiprismatic geometry. In the crystal structure, intra- and intermolecular N-H...O, N-H...N and O-H...N hydrogen bonds link the cations and anions in an alternating fashion, forming a two-dimensional layered structure, in which they are further linked through the very weak [pi]-[pi] stacking interactions [shortest distance = 4.640 (2) Å] and van der Waals forces between adjacent layers, forming a three-dimensional supramolecular network.

Comment top

Heterometallic cyanido-bridged 4f-4d or 4f-5d assemblies are of high interest in molecular magnetism over the recent years (Chelebaeva et al., 2008; Przychodzeń et al., 2007; Ikeda et al., 2005; Kosaka et al., 2007; Matoga et al., 2005; Wang et al., 2006). The combination of the octacyanometalate [M(CN)8]3-/4- (M = Mo, W, Nb) building blocks with the lanthanide ions are of interest not only in materials science but also in physics and theoretical chemistry, providing interesting cases of investigation. Herein, we employed 4,4'-azpy (4,4'-azobispyridine), [WV(CN)8]3-, and Ce3+ as building blocks in order to obtain a new lanthanide-containing octacyanotungstate(V)-based magnet. However, the unexpected supramolecular title complex without Ce3+ was obtained. We report herein its crystal structure.

The asymmetric unit of the title complex contains two 4,4'-diazenediyldi- pyridinium, [H2(4,4'-azpy)]2+, and two (4-pyridyldiazenyl)pyridinium, [H(4,4'-azpy)]+, cations, two [WV(CN)8]3- anions, and four uncoordinated water molecules (Fig. 1). Each of the W centers is coordinated by eight CN groups in a slightly distorted square antiprism. The average W-C bond distances are 2.153 (8) Å (for W1) and 2.178 (8) Å (for W2).

In the crystal structure, intra- and intermolecular N-H···O, N-H···N and O-H···N hydrogen bonds (Table 1) link the [H2(4,4'-azpy)]2+ and [H(4,4'-azpy)]+ cations and [W(CN)8]3- anions in an alternating fashion to form a two-dimensional layered structure (Fig. 2), in which they are further linked through the highly weak π–π stacking interactions [shortest distance = 4.640 (2) Å] and van der Waals forces between adjacent layers to form a three-dimensional supramolecular network (Fig. 3) as in the similiar complex (C10H10N4)(C10H9N4)[Mo(CN)8].4H2O (Liu et al., 2008).

Experimental top

Single crystals of the title complex were prepared at room temperature in the dark by slow diffusion of an acetonitrile solution (2 ml) containing both Ce(NO3)3.6H2O (21.71 mg, 0.05 mmol) and 4,4'-azpy (9.21 mg, 0.05 mmol) in an acetonitrile solution (20 ml) of [HN(n-C4H9)3]3[W(CN)8].4H2O (46.60 mg, 0.05 mmol). After two weeks, pale yellow crystals were obtained.

Refinement top

H atoms were positioned geometrically with O-H = 0.85 Å (for H2O), N-H = 0.86 Å (for NH) and C-H = 0.93 Å, for aromatic H atoms, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C,N,O), where x = 1.5 for H2O H and x = 1.2 for all other H atoms.

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.
