A single crystal of Ni(II)bis(3,4 dimethoxybenzoate)bis(nicotinamide) dihydrate, formulated as C30H34N4NiO12 (I), was characterized in the solid state by infra-red (IR), ultra-violet (UV) and single crystal X-ray diffraction analysis at 296 K as mononuclear with a distorted octahedral stereochemistry. The complex consists of a six-coordinate Nickel atom in a distorted octahedral environment constructed from two N atoms and four O atoms and crystallizes in the monoclinic space group C 2/c with a=27.7680(16) Å, b=8.5748(3) Å, c=17.8018(9) Å, α=90°, β=108.154(4)°, γ=90°, Z=4. The molecular structure and geometry was also optimized using the B3LYP density functional theory method employing the 6-31G(d) basis set. The molecular electrostatic potential (MEP), frontier molecular orbitals (FMO) analysis, nonlinear optical properties (NLO) and natural bond analysis (NBO), Mulliken population analyis, natural population analysis (NPA) and Fukui function analysis were also described.

A single crystal of Zn(II)bis(3,4 dimethoxybenzoate)bis(nicotinamide) dihydrate, formulated as C30H38N4O 14Zn, (I) has been obtained. According to experimental data, the complex can be characterized in the solid state as mononuclear, with a distorted octahedral stereochemistry. The distorted octahedral stereochemistry adopted by the complex was further confirmed by X-ray structure analysis of the current study, which consists of a six-coordinate Zn atom in a distorted octahedral environment constructed from two N atoms and four O atoms. The title compound crystallizes in the monoclinic space group C 2/c with a = 27.9248(18) Å, b = 8.5941(4) Å, c = 14.8344(11) Å, α = 90°, β = 108.651(5), γ = 90°, Z = 4. The molecular structure and geometry were also optimized using the B3LYP density functional theory method employing the 6-31G (d) basis set. Molecular electrostatic potential, frontier molecular orbital analysis, nonlinear optical properties and natural bond analysis for the title molecule are also described from the computational process.
