“…The Ni-S bond lengths involving the xanthate ligands are 2.421(4) Å for Ni1-S2 and 2.461(5) Å for Ni1-S3. The bond angles in the pyridine ring vary from 117.7(2) to 122.8 (2) o , the average value being 119.9 (9) o and these values of bond angles and bond distances are in good agreement with those reported for other analogous Ni-dithiocarbonato complexes 21,22 .

A series of six coordinated Ni(II)complexes with general formula [Ni(C 5 H 4 NCl) 2 (S 2 COC 3 H 7 ) 2 ] was synthesized and characterized. All the complexes have 1:2 stoichiometry, are non ionic and paramagnetic in nature. TGA-DTA studies show the formation of NiS as the stable end product of the decomposition. One of the adducts bis(O-propyldithiocarbonato)bis (3-chloropyridine) nickel(II) crystallizes in the monoclinic space group P21/c. The Ni 2+ ion is in an octahedral coordination environment formed by an N 2 S 4 donor set, defined by two chelating dithiocarbonate anions as well as two 3-chloropyridine ligands with the Ni 2+ ion located at the inversion centre. The packing of layers of molecules is stabilized by weak π -π and C-H···π interactions. The asymmetric unit comprises of half molecule and Nickel(II) cation lies on an inversion centre.

“…The Ni-S bond lengths involving the xanthate ligands are 2.440(9)Å for Ni1-S1 and 2.433(1)Å for Ni1-S2. The bond angles in the pyridine ring vary from 117.0(3) to 123.8(3) ∘ , with the average value being 119.9(8) ∘ , and these values of bond angles and bond distances are in good agreement with those reported for other analogous Ni-dithiocarbonato complexes [30][31][32]. The C-S bond lengths involving the xanthate ligands are S1-C3 = 1.691(4) and S2-C3 = 1.691(4)Å.…”

The [Ni(S2CO-n-C5H11)2(C6H4N2)2] adduct of 4-cyanopyridine with [Ni(S2CO-n-C5H11)2] was synthesized and characterized by elemental analysis, magnetic susceptibility measurement, IR, electronic spectral data, and X-ray diffraction analysis. The Ni atom in the title complex is octahedrally coordinated within a trans-N2S4 donor set, with the Ni atom located on a centre of inversion. The title compound exhibits magnetic moment value (3.20 B.M) which is in agreement with magnetic moment values observed for paramagnetic octahedral complexes of nickel(II). The title complex crystallizes in the orthorhombic space group Pbca with unit cell parameters a = 11.455(5), b = 9.602(4), and c = 26.374(1) Å. Crystal structure was solved by direct methods and refined by full matrix least-squares procedures to a final R value of 0.0499 for 2004 observed reflections. The amyl chain is disordered over two sets of sites, with occupancy ratios of 0.595 : 0.405. Infinite long chains of molecules are formed with the help of C–H⋯N hydrogen bond.

“…The Ni1-N1 bond length is 2.114(1) Å while the Ni1-S1 and Ni1-S2 bond lengths are 2.460(5) and 2.429(4) Å , respectively. The Ni-S bond distances find a good match with the values reported for an analogous structure of bis(O-butyldithiocarbonato)bis (4-cyanopyridine)nickel(II) [27]. The two sulphur-carbon distances show double bond character due to the delocalization over the two C-S bonds [28].…”

“…The cyano group located at C4 is out of the plane of the phenyl ring as the torsion angle C3-C4-C7-N2 = 23(6)°. The out-of-plane position of the cyanide group is also evident from the least-squares plane calculation of the pyridine ring where the C7 atom is found below the pyridine ring (deviation for C7 atom being -0.082 (2) [27,28]. The dihedral angle between the least-squares plane of dithio-group and the pyridine ring is 88.12°meaning thereby that both the units are held almost perpendicular to each other.…”
