Abstract
The title compound, [Ni(C6H8N2)(3)]Cl-2.2(H2O), was synthesized by slow evaporation method at room temperature. The structural study by X-ray diffraction indicate that this compound crystallize in the triclinic system, P-1 space group with a = 10.222(2) angstrom, b = 10.757(2) angstrom, c = 11.441(3) angstrom, alpha=114.30(4)degrees, beta=99.43(3)degrees and gamma=93.01(3)degrees. The structure is formed by the cation [Ni(C6H8N2)(3)](2+), tow chloride anions and two molecules water of crystallization. The nickel (II) atom is coordinated to six nitrogen donors from three neutral 2-AMP ligands, adopting a slightly distorted octahedral geometry. The crystal structure is stabilized by strong hydrogen bonds of N-H center dot center dot center dot Cl, O-H center dot center dot center dot Cl, C-H center dot center dot center dot Cl and pi-pi interactions to obtained three-dimensional network. The newly prepared compound was characterized by XRD, Infrared, UV-Vis spectroscopy and Hirshfeld surface (3D-HS) analysis. Vibrational analysis of the compound was realized by infrared spectroscopy. The optical properties of the crystal were studied using optical absorption UV-visible spectroscopy which confirmed the semiconducting properties by revealing a direct optical band. Hirshfeld Surface projections and Fingerprint plots were elucidated the relative contribution of the H center dot center dot center dot Cl, C center dot center dot center dot H, C center dot center dot center dot C, C center dot center dot center dot N, H center dot center dot center dot O intermolecular contacts in the crystal.
