【Abstract】 A dinuclear cobalt(Ⅲ) complex,[Co2OL2]Cl2(ClO4)2,has been synthesized by reaction of 2-(bis(2-aminoethyl)amino)ethanol(L) with CoCl3·6H2O. The crystal structure analyzed by X-ray diffraction methods has shown that the complex crystallizes in the monoclinic system,P21/c space group.The complex consists of cationic unit of [Co2OL2]4+ and two noncoordinated chloride ions and two perchlorate ions.In the cationic unit of the complex,each Co(III) is coordinated by three nitrogens of diethylenetriamine moiety and bridged by one oxygen and two hydroxo groups of two 2-(bis(2-aminoethyl)amino)ethanols.The two Co(Ⅲ) ions are 2.527(1) apart from each other.The bond distances of six Co-N bonds are from 1.896(6)) to 1.944(6),the bond distances of six Co-O bonds are from 1.901(5) to 1.939(4)?.Each Co(Ⅲ) ion adopts a distorted octahedral configuration in the N3 and bridged O3 environment.The dihedral angle between the planes of N1,N2,Co1,O1,O2 and O1,O2,Co2,N4,N6 is 63.1(2)°.更多还原
