In the 2(C12H10ClN)2], the Zn2+ cation is N-coordinated by two terminally bonded thiocyante anions and by two 4-(4-chlorobenzyl)pyridine ligands within a slightly distorted tetrahedron. The consists of half of the discrete complex, the central Zn2+ cation of which is located on a twofold rotation axis. The discrete complexes are linked into layers via a weak intermolecular hydrogen-bonding interaction, with a H⋯Cl distance of 2.85 Å and a C—H⋯Cl angle of 151°. These layers extend parallel to the ab plane and are held together by dispersion forces only.

ZnSO4·H2O was purchased from Merck and 4-(4-chlorobenzyl)pyridine and Ba(NCS)2·3H2O were purchased from Alfa Aesar. Zn(NCS)2 was synthesized by stirring 17.5 g (57.00 mmol) Ba(NCS)2·3H2O and 10.23 g (57.00 mmol) ZnSO4·H2O in 300 mL water at RT for three hours. The white residue of BaSO4 was filtered off, and the solution was evaporated by heating. The
of the product was investigated by X-ray powder diffraction and elemental analysis. The title compound was prepared by the reaction of (0.6 mmol) 108.9 mg Zn(NCS)2 and (0.15 mmol) 105.5 µL 4-(4-chlorobenzyl)pyridine in 1.5 mL acetonitrile at RT. After few days, colorless needle-like crystals of the title compound were obtained.Data collection: X-AREA (Stoe, 2008); cell

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |
