In the title compound, [ZnCl2(C9H17N3S)2], the ZnII atom is four-coordinated by two N atoms from two 5-heptyl-1,3,4-thiadiazol-2-amine ligands and two Cl atoms in a distorted tetrahedral geometry. The thiadiazole rings are oriented at a dihedral angle of 84.87 (4)°. Intramolecular N—H⋯Cl interactions result in the formation of two six-membered rings having envelope and planar conformations. In the intermolecular N—H⋯N and N—H⋯Cl interactions link the molecules into a three-dimensional network. π–π contacts between thiadiazole rings [centroid–centroid distance = 3.602 (1) Å] may further stabilize the structure.

For the preparation of the title compound, ZnCl2 ethanol solution (0.5 mmol) was slowly added into a solution of 5-heptyl-[1,3,4]thiadiazol-2-ylamine (1 mmol) in ethanol (20 ml), and then heated under reflux for 2 h. The reaction mixture was left to cool to room temperature, filtrated, and the solid was recrystallized from ethanol to give the title compound (m.p. 426 K). Crystals suitable for X-ray analysis were obtained by slow evaporation of an acetone solution.
H atoms were positioned geometrically, with N-H = O.86 Å (for NH2) and C-H = 0.97 and 0.96 Å for methylene and methyl H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C,N), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

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. |

As a series of superior ligands, thiadiazoles and their derivatives can coordinate to many metal ions with N or S atoms of the five-membered ring. In particular N,N'-linkage ligands, such as 1,3,4-thiadiazoles, are very versatile compounds that are able to bridge a wide range of inter-metallic separations through two close adjacent N donors (Alzuet et al., 2003). These complexes have received considerable attention in past few years, due to their certain antibacterial and antifungal activities (Shen et al., 2004).
In the molecule of the title compound, (Fig. 1), ZnII atom is four-coordinated by two N atoms from two 5-heptyl-[1,3,4]thiadiazol-2-ylamine ligands and two Cl atoms in a distorted tetrahedral geometry (Table 1). Rings A (S1/N1/N2/C8/C9) and B (S2/N4/N5/C10/C11) are, of course, planar and they are oriented at a dihedral angle of A/B = 84.87 (4)°. The intramolecular N-H···Cl interactions (Table 2) result in the formations of two six-membered rings C (Zn/Cl1/N1/N3/C9/H3A) and D (Zn/Cl2/N4/N6/C10/H6A). Ring C adopts envelope conformation with atom Zn displaced by -0.318 (3) Å from the plane of the other ring atoms, while ring D is planar and it is oriented with respect to the adjacent ring B at a dihedral angle of B/D = 1.08 (4)°. So, they are almost coplanar.
In the crystal structure, intermolecular N-H···N and N-H···Cl interactions (Table 2) link the molecules into a three-dimensional network (Fig. 2), in which they may be effective in the stabilization of the structure. The π–π contact between the thiadiazole rings, Cg2—Cg2i, [symmetry code: (i) 1 - x, 1 - y, 1 - z, where Cg2 is centroid of the ring B (S2/N4/N5/C10/C11)] may further stabilize the structure, with centroid-centroid distance of 3.602 (1) Å.
