It crystallizes in the monoclinic system, space group P21/c. The lattice parameters are a=11.855(2)?, b=14.722(3)?, c=12.080(2)?, β=117.32(3)°, V=1879.4(7)?3 , Z=4 with R1=0.0330. The structure is made of heterobinuclear units . The copper atom is coordinated by two nitrogens, two phenolic oxygens, in a square planar manner. And the cobalt atom is coordinated by two phenolic oxygen atoms, two equatorial carboxyl oxygen atoms and one axial water oxygen atom, in a distorted square pyramid. Two metal atoms are bridged by two phenolic oxygens. In the crystal packing, the neutral molecules built layers. Within these layers the molecules are connected through hydrogen bonds. And the thermal property of the complex according to crystal structure is also investigated.展开更多
