The crystal structure of the title complex has been determined by single crystal X ray diffraction techniques. The crystal belongs to monoclinic with space group P21/c. The cell parameters are: a=1.6362(9)nm, b=1.7140(9)nm, c=1.2255(7)nm, β=105.168(9)°, V=3.317(3)nm3, Z=8, Dc=1.525g·cm-3, μ(MoKα)=1.334mm-1, F(000)=1560. The structure wasrefined to final R1=0.0376, wR2=0.0909. The copper?ion lies in a distorted square planar environment composed of two oxygen atoms, one nitrogen atom of tridentate acyhydrazone Schiff base ligand and one nitrogen atom of the pyridine ligand.

The crystal structure of the title complex has been determined by single crystal X-ray diffraction techniques. The crystal belo ngs to orthorhombic, space group Pbca. The cell parameters are: a=1.580 20(19) n m, b=1.362 18(16) nm, c=1.616 50(19) nm, and V=3.479 5(7) nm3, Z=8, Dc=1.497 Mg ·m-3, composed of two oxygen atoms, one n itrogen atom of tridentate acyhydrazone schiff base ligand and one nitrogen atom of the pyridine ligand. The analysis of the crystal structure indicates that th e complex has a one-dimensional chain structure, which is formed by intermolecul ar hydrogen bonds. CCDC: 244668.展开更多
