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)? V = 676.4(2) 3, Z = 2, F(000) = 342 and m(MoK? = 1.629 mm-1 .展开更多

The complex crystallizes in the triclinic crystal system, P1 space group, a = 0.9610(1) nm, b = 0.9684(1) nm, c = 0.7924(1) nm, α = 96.695(9)°, β = 102.741(6)°, γ = 116.551(5)°, V = 0.6236(2) nm3, Z = 2, R1 = 0.0342, wR2 = 0.0990. The surface photovoltage spectra measurement shows that the title com- plex exhibits obvious photovoltage response in the 300—800 nm regions. The variable temperature susceptibility reveals that the complex possesses weak antiferromagnetic property.展开更多
