Synthesis and Crystal Structure of Nickel(II) Complex Derived from Benzotriazole-4-Sulfonate

Abstract

A novel complex [Ni(C₁₀H₈N₂)₂(C₇H₆N₃SO₃)][OH]·2.5H₂O was synthesized and characterized by IR spectra, elemental analysis and single-crystal X-ray. The crystal structure analysis shows that the Ni(II) is a six-coordinated in a distorted octahedron environment, then complex packs in 3D-superamolecular network through intermolecular hydrogen bonds and p-p staking. The crystal is orthorhombic, space group Pccn with unit cell parameters: a = 30.142(4) Å, b = 10.4659(16) Å, c = 18.497(3) Å, V = 5835.1(15) Å3, Z = 4, Mr = 1289.66, Dc = 1.468 Mg/cm³, μ = 0.792 mm^-1, F(000) = 2676, T = 293(2) K, R = 0.0466, wR = 0.1582 for 5726 reflections with I > 2s(I).
