摘要

The structure of the complex [Co(PMBP-tsc)2.2DMF@2H2O]( PMBP-tsc= 1-phenyl-3-methyl-4-benzoylpyrazol-5-one-thiosemicarbazone) has been determined by X-ray crystallography. It crystallizes in the orthorhombic system, space group Pna21, with lattice parameters a=2.1170(3) nm, b =1.2780(10) nm, c = 1.8956(2) nm, V= 4.5258(9) nm3 and Z=4. The structure shows that Co2+ in the complex is hexacoordinated with a distorted octahedral coordination sphere.The water molecules bridge the adjacent stacks through hydrogen bonds and lead to supramolecular formation with three-dimensional network structure.
