Dong Li

Abstract

A novel copper(Ⅱ) complex [Cu(NPA)_2(Im)_2(H_2O)]·H_2O has been synthesized (NPA=N-phenylanthranilic acid and Im=imidazole) and characterized by IR, elemental analysis and X-ray single crystal diffraction methods. It Crystallizes in Triclinic system, space group P1 with a=0.987 9(2) nm, b=1.075 7(3) nm, c=1.559 7(5) nm, α=104.18(10)°, β=108.14(10)°, γ=92.69(10)°, V=1.513 39(7) nm3, Z=2, Dc=1.447 g·cm-3, F(000)=684, R1=0.028 0, wR=0.083 1. The Cu(Ⅱ) ion in the title complex is coordinated with two oxygen atoms from two N-phenylanthranilic acid in monodenate mode, two nitrogen atoms form two imidazole, and one oxygen atom from water, forming a distorted square-pyramid coordination geometry. CCDC: 638653.
