-2-Pyridinealdazine-
4N,N':N'',N''')bis[bis(N,N-di-n-propyldithiocarbamato-
2S,S')cadmium(II)]The dinuclear centrosymmetric title compound, [Cd2(C7H14NS2)4(C12H10N4)], features a tetradentate 2-pyridinealdazine ligand that chelates two Cd centres. The coordination geometry for Cd is distorted octahedral based on a cis-N2S4 donor set. In the crystal structure, molecules are connected into a supramolecular chain aligned along the a direction via C-H
S and C-H
contacts, and by

contacts [centroid-to-centroid distance 3.5708 (15) Å]. The n-propyl groups are each disordered, one equally over two sites and the other with a site-occupancy factor of 0.618 (8) for the major component.
Compound (I) was prepared by standard methods (Benson et al., 2007) and red crystals were grown by the slow evaporation of a methanol–ethanol (1/1) solution of (I), m.p. 441-443 K. IR (cm-1): 1474 (s, C═N), 1171 (s, C—S). TGA: One broad step with onset = 625 K, midpoint = 662 K, and endset = 711 K which corresponds to decomposition leading to CdS (mass loss 79.4% cf. theoretical mass loss = 74.4%).
The H atoms were geometrically placed (C—H = 0.95–0.99 Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl-C). The N1-bound n-propyl groups were each found to be disordered. The C6—C7 residue was disordered over two positions, each with 50% site occupancy factors (from anisotropic refinement). The C3 atom of the C2—C4 residue was disordered over two positions with the major component having a site occupancy factor = 0.618 (8) (from anisotropic refinement).

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. |

Metal dithiocarbamates have recently been applied in crystal engineering studies (e.g. Tiekink, 2006; Benson et al., 2007). The title compound, {[(nPr)2NCS2]2Cd(2-C5H4N—C(H)═N—N═C(H)C5H4N-2)- Cd[S2CN(nPr)2]2} (I), features a centrosymmetric tetradentate 2-pyridinealdazine ligand coordinating to two Cd centres each of which is chelated by two dithiocarbamate ligands, Fig. 1. The molecule is centrosymmetric about the central N—N bond. The range of Cd—S bond distances is relatively narrow at 2.6124 (8) to 2.7165 (7) Å, but the Cd—N bond formed by the pyridine-N of 2.377 (2) Å is significantly shorter than the Cd—N bond distance of 2.6211 (19) Å formed with the azo-N atom. The coordination geometry is based on an octahedron within a cis-N2S4 donor set. The structure reported here for (I) resembles closely the dithiophosphate analogue (Lai & Tiekink, 2006). In the crystal structure, molecules are connected into a supramolecular chain, aligned along the a-direction and illustrated in Fig. 2, via C—H···S3 and π–π contacts. The latter occur between centrosymmetically related N3,C15—C19 rings with Cg···Cg = 3.5708 (15) Å. These are consolidated into the crystal structure via additional C—H···S4 contacts and C—H···π interactions, Table 1 and Fig. 3.
