Synthesis and characterization of thiolato-bridged cadmium(II) complexes with NNS-chelating thiolic ligands

摘要

Cadmium(II) complexes with 2-[(2-aminoethyl)amino]ethanethiol (HL~1).2-[(aminopropyl)amino]ethanethiol (HL~2),2-[(2-pyridylethyl)amino]ethaethiol (HL~3),and 2-[[(2-(2-pyridyl)ethyl]amino]ethyl]amino]ethanethiol (HL~4),[Cd(L~1)](ClO_4)(1),[Cd(L~2)]-(ClO_4)centre dot 1/2CH_3OH (2),[Cd{Cd(L~2)_2}_2](ClO_4) (5),have been synthesized and characterized bymeasurements of the infrared and electronic spectra.The S-ray crystal strctures show that 3a and 3b have a thiolato-bridged trnuclear core witha linear arrangement of three metalatoms.
