Abstract

The tridentate ligand H2L (H2L = β-phenylalanine, N-[1-(2-hydroxyphenyl)propylidene] reacts with copper(II) nitrate and imidazole to give binuclear compound [Cu2L2(imi)2] (1). The coordination geometry of each copper(II) ion is best described as a square-pyramided with one nitrogen atom, two oxygen atoms of the ligand one nitrogen atom of imidazole and one carboxylate oxygen atom belong to another ligand. It crystallizes in the monoclinic system P−1 with a = 7.8439(12) Å, b = 10.2717(16) Å, c = 11.6885(18) Å, α = 76.672(2)°, β = 85.397(2)°, γ = 71.412(2)°, V = 868.6(2) Å3, Z = 1.

Index Abstract

Crystal structure of 1 [Cu2L2(imi)2] reveals a binuclear compound with eight-member ring (shown in green color), in which the coordination environment around each copper(II) ion exhibits a distorted square-pyramidal geometry
