The binuclear title compound, [Cu2(C12H10N6S2)Cl2], possesses twofold rotational symmetry. The CuII atom occupies a four-coordinate pseudo-tetra­hedral environment bound to one S atom, one imine N atom and one pyridine N atom from the N1,N2-bis­(pyridin-2-yl)hydrazine-1,2-dicarbo­thio­amidate ligand, and one Cl anion. The metal atoms are connected via the bis-tridentate ligand into a binuclear structure. The mol­ecule is bow-shaped with the pyridine rings inclined to one another by 51.56 (14)°. In the crystal, N—H⋯Cl hydrogen bonds lead to the formation of ribbons propagating along [001]. These ribbons are connected via C—H⋯Cl, C—H⋯S and ππ inter­actions [centroid–centroid distance = 3.6146 (19) Å], leading to the formation of a three-dimensional structure.

Thiosemicarbazide and their metal complexes have attracked considerable interest due to their biological activities, such as antiviral, antibacterial, antimalarial, antifungal, and antitumoral activities (West et al., 1993). Thiosemicarbazide are versatile ligands that can coordinate as neutral ligands or in the deprotonated form. They can also be used as flexible spacers with potential multiple binding sites to construct coordination polymers with multiple dimensions and various topologies. In the present paper, the synthesis and crystal structure of the title thiosemicarbazide binuclear copper(II) compound is reported.

The title compound possesses twofold rotational symmetry (Fig.1). Each CuII center occupies a four-coordinated pseudotetrahedral environment bound to one sulfur atom, one imine nitrogen atom, and one pyridine nitrogen atom from one N,N'-di(pyridin-2-yl)hydrazine-1,2-bis(carbothioamide) ligand, and one chlorine anion. The metal centres are connected via the hexadentate ligand into a binuclear structure. The molecule is bow-shaped. The thiosemicarbazide moiety (S2/N2(N3/N6) is twisted by 20.14 (13)° from the pyridine ring to which it is attached. The two thiosemicarbazide moieties, (S2/N2/N3/N6) and (S2A/N2A/N3A/N6A), are inclined to one another by 23.36 (13) °, while the pyrdine rings make a dihedral angle of 51.56 (14)°.

The Cu—S distance is 2.2295 (9) Å, and the Cu—N distances vary between 1.961 (3)–1.986 (2) Å. The C—S bond distances of 1.711 (3) Å are within the normal range for a C—S single bond, indicating that the thiosemicarbazide moieties adopt the thiol tautomeric form, acting as a doubly charged negative ligand. The C6—N distances of 1.311 (3)–1.366 (3) Å and the N3—N3A distance of 1.399 (3) Å are intermediate between formal single and double bonds, pointing to extensive electron delocalization over the entire ligand skeleton. This agrees well with the same distances observed in related compounds (Wang et al., 2011; Yamin & Yusof, 2003; Akinchan et al., 2002).

In the crystal, there are N-H···Cl hydrogen bonds, leading to the formation of ribbons propagating along [001], and C-H···Cl and C-H···S interactions (Table 1). The latter link the ribbons and together with ππ interactions lead to the formation of a three-dimensional structure [Cg1···Cg1i 3.6146 (19) Å; perpendicular separation 3.5312 (11) Å; slippage 0.772 Å; Cg1 is the centroid of pyrdine ring N1/C1-C5; symmetry code: (i) -x, -y+2, -z].

Experimental top

The ligand (L), N,N'-di(pyridin-2-yl)hydrazine-1,2-bis(carbothioamide,) was prepared by the literature method (Szecsenyi et al., 2006). L (0.05 mmol) was solved in DMF (5 ml) in a test tube, then an 8 ml solvent mixture of CH3OH and DMF (v/v = 1:1) was added as a buffer layer. A solution of CuCl2(0.10 mmol) in CH3OH (3 ml) was then carefully layered on top. The system was sealed and kept for a week, after which black block-like single crystals, suitable for X-ray analysis, were obtained. Anal. Calcd for C12H10Cl2Cu2N6S2: C 28.80, H 2.01, N16.80.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles

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.
