摘　　要： The novel copper(Ⅱ) complex with α-hydroxyphenylacetic acid (H2PHAc) and pyridine (py) ligands, [Cu(HPHAc)2(py)2], has been synthesized and characterized by elemental analysis and IR spectroscopy. Its crystal structure was determined by single crystal X-ray diffraction techniques. The crystal belongs to monoclinic with space group C2/c. The cell parameters are: a=1.712 5(3) nm, b=1.533 2(2) nm, c=0.963 42(14) nm, β=111.866(2)°, V=2.347 6(6) nm3, and Dc=1.483 Mg·m-3, Z=4, F(000)=1 084. The structure was refined to final R1=0.071 4, wR2=0.166 1. The complex has a six-coordinated distorted octahedral geometry, in which copper(Ⅱ) ion coordinates with two carboxylic oxygen atoms and two hydroxyl oxygen atoms from the two α-hydroxyphenylacetic acid ligands, two nitrogen atoms from the two pyridine ligands. The analysis of the crystal structure indicates that the complex has a one-dimensional chain structure, which is formed by intermolecular hydrogen bonds. CCDC: 255346.
