The title compound was prepared by refluxing the parent zinc dithiophosphate with 4-pyridinealdazine (Aldrich) using a literature procedure (Lai et al., 2004a). Colourless crystals were isolated in 65% yield by slow evaporation of a chloroform–acetonitrile (3:1 (v/v) solution of the compound (m.p. 377–379 K). Analysis found: C 50.38, H 6.34%; C36H54N4O4P2S4Zn requires: C 50.14, H 6.31%. IR (KBr disk): ν(C—O) 1153 (m), ν(P—O) 968 (s), ν(P—S)asymm 658 (m), ν(P—S)symm 523 (m) cm−1.
H atoms were included in the riding-model approximation, with aromatic C—H = 0.94 Å, methine C—H = 0.99 Å and methylene C—H = 0.98 Å, and with Uiso(H) = 1.2Ueq(C). The C1–C6 cyclohexyl group was disordered and two sites were discerned for atoms C5 and C6. As the occupancy for each site refined to nearly 50%, the occupancies of the disordered atoms were fixed at 50%.

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. |

Interest in crystal structures related to the polymeric title complex, [Zn{S2P(OCy)2}2{4-NC5H4C(H)═NN═C(H)C5H4N-4}]n, (I), arises from the desire to rationalize the formation of polymer topologies based on the steric requirements of the respective ligands, i.e. dithiolate-bound R groups and/or the dipyridyl-type ligands themselves (Lai et al., 2002, 2004a; Tiekink, 2003; Lai & Tiekink, 2004).
The immediate coordination geometry about the Zn atom (Fig. 1) is defined by four S atoms, derived from two chelating dithiophosphate ligands, and two N atoms, derived from two µ2-bridging dipyridyl-type ligands. There is crystallographic symmetry in the structure so that the Zn atom is located on a twofold axis and each dipyridyl-type ligand is disposed about a centre of inversion. The cis-N2S4 donor set defines an octahedral geometry with the major distortion being due to the restricted bite distance of the dithiophosphate ligand, i.e. the S1—Zn—S2 chelate angle is 79.17 (2)°. Other geometric parameters are as expected (Table 1).
The cis disposition of the N-donor atoms gives rise to a polymer with a zigzag topology (Fig. 2). The polymer is aligned along the c axis and a small twist in the dipyridyl-type ligand is noted, as seen in the N2—C18—C15—C16 torsion angle of 19.8 (4)°. It is noteworthy that in the absence of any obvious steric hindrance in the structure of (I), a zigzag polymer is found, an observation consistent with the majority of structures of the general formula [Zn{S2P(OR)2}2(bridging dipyridyl-type ligand)]n. Thus, for each of the [Zn{S2P(OR)2}2(4-NC5H4C5H4N-4)]n, for R = Et (Zhu et al., 1996) and R = iPr (Glinskaya et al., 2000), and [Zn{S2P(OR)2}2(4-NC5H4CH2CH2C5H4N-4)]n, R = iPr and Cy (Lai et al., 2004a) structures, a zigzag topology is found. By contrast, in the two cases where steric influences become a factor in polymer formation, a linear chain is formed, i.e. [Zn{S2P(OCy)2}2{4-NC5H4C(H)═C(H)C5H4N-4}]n (Lai et al., 2004a) and [Zn{S2P(OiBu)2}2(4-NC5H4CH2CH2C5H4N-4)]n (Lai et al., 2004b).
