Abstract
The crystal structure of bis(O-ethyldithiocarbonato-κ2S,S′)bis(4-ethylpyridine-κN) nickel(II) [Ni(S2COCH2CH3)2(NC5H4-CH2CH3)2] has been elucidated by a single-crystal X-ray diffraction method. The complex crystallizes in the orthorhombic space group Pbca with unit-cell parameters a = 14.174(5), b = 17.153(5), c = 20.496(5)Å. The crystal structure was solved by direct methods and refined by full-matrix least-squares procedures to a final R-value of 0.0571 for 2621 observed reflections. The two pyridine rings are coplanar and are held almost perpendicular to the dithiocarbonato groups. The compound has a trans octahedral geometry. Packing is stabilized by C-H…S intermolecular hydrogen bonding.
