The copper(Ⅱ) atoms has a planae-square (N 2O 2) geometry,which positions are occupied by two nitrogen atoms and one oxygen atom from the Schiff base ligand and the other carboxy oxygen atom from the adjacent ligand.The carboxylate groups acted in the bidentate syn-anti mode and bridges each pair of adjacent copper(Ⅱ) atoms( d Cu...Cu Ca 4.8*!) via the two equatorial positions,giving rise to one-dimensional (Cu-O-C-O-Cu) n skeletons.展开更多

It was found that the local coordination geometry around Cu(Ⅱ) is a distorted tetrahedron and C14H9CuNO3CH3OH is bridged by the carboxylate oxygen atom to form an infinite one-dimensional linear chain. The hydrogen bond exists between O(1) and solvate molecule O(4). The crystal belongs to monoclinic, space group P21 with a = 9.6650(19), b = 7.1280(14), c = 9.925(2) ? b = 98.39(3)?
