摘要：The novel copper(Ⅱ) complex with α-hydroxyphenylacetic acid (H2PHAc) and pyridine (py) ligands,[C...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: α=1.7125(3)nm, b=1.5332(2)nm, c=0.96342(14)nm,β=111.866(2)°,V=2.3476(6)nm^3, and Dc=1.483Mg·m^-3, Z=4, F(000)=1084. The structurewas refined to final R1=0.0714, ωR2=0.1661. 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.显示全部
