Synthesis and Crystal Structure of a New 3D Complex [Cu(N-phthgly)_2(H_2O)_2]·C_2H_5OH Constructed by Hydrogen Bonds

A copper(Ⅱ) complex [Cu (N-phthgly)2 (H2O)2]·C2H5OH (N-Hphthgly =N-phthaloylglycine) has been synthesized and characterized by elemental analysis, infrared spectroscopy and X-ray crystallography. The complex crystallizes in triclinic space group P1 with a=0.472 90(7) nm, b=1.080 01(13) nm, c=1.154 02(15) nm, α=74.360 0(10)°, β=79.151 0(10)°, γ=87.918(2)°, V=0.557 37(13) nm3, Z=1. The central copper atom allows the formation coordination environment with two O(5) atoms of two water ligands and two O(1) atoms of two N-phthgly ligands. The complex forms a step-like 3D structure through the three types of O-H…O hydrogen bonds and the Cu…O weak interaction. CCDC: 712945.
