Synthesis and Crystal Structure of a New Chiral Mononuclear Complex: [Cu(C10H12N2O)2(NO3)2(H2O)]

Abstract

A novel chiral mononuclear complex [Cu(C₁₀H₁₂N₂O)₂(NO₃)₂(H₂O)], where C₁₀H₁₂N₂O) is 3-(dimethylamino)-1-(pyridine-4-yl)prop-2-en-1- one, was synthesized and characterized by IR spectra, elemental analysis and single-crystal X-ray. The crystal structure analysis shows that the copper(II) is a five-coordinated with a chiral space group in a slightly distorted square pyramidal geometry environment. The crystal is monoclinic, space group Cc with unit cell parameters: a = 20.399(2)Å, b = 9.780(1)Å, c = 13.537(2)Å, α = 90º, β = 116.270(2)º, γ = 90º, V = 2421.8(5) ų, Z = 4, Mr = 558, Dc = 1.531 Mg/cm³, μ = 0.964 mm^-1, F(000) = 1156, Flack x = 0.39(2), T = 291(2) K, R = 0.0561, wR = 0.0979 for 3513 reflections with I > 2σ(I).
