摘要：
A one- dimensional coordination polymer [ Co(mu(1,3)-NCS)(2)(npdo)(2)](n) (npdo=4- nitropyridine N- oxide) has been synthesized and structurally determined by X- ray crystallography. The complex crystallizes in the orthorhombic space group of Pbcn with a=22.688( 5) angstrom, b=7.2636(17) angstrom, c=10.299(2) angstrom. Adjacent Co(II) ions are coordinated by two mu(1,3)-SCN(-) bridging ligands, forming a one- dimensional chain along the c axis and the npdo coordinates to Co( II) ion as a terminal ligand. The thermal variation of the magnetic moments of the complex reflects the antiferromagnetic interaction between the bridged Co( II) ions above 20K and the ferromagnetic transition or the strong short- range spin interaction below 20 K.
