Abstract

Abstract: Four cobalt compounds containing a novel structural unit[Co₃(SS)₃(PR₃)₃]:Co₃(bdt)₃(PBu₃)₃(Ⅰ),Co₃(tdt)₃(PBu₃)₃(Ⅱ),[Co₃(bdt)₃(PPh₃)₃][CoBrt(dmf)](Ⅲ)and[Co₃(edt)₃(PEt₃)₃]₂[Co₂Cl₄(Et₂SO₂)₂](Ⅳ)(bdt=1,2-S₂C₆H₄^2-,tdt=4-Me-1,2-S₂C₆H₃^2-,edt=SCH₂CH₂S^2-) were studied by means of magnetic susceptibllity and ¹H NMR. The results indicate that they are paramagnetic compounds with antiferromagneticcoupling among the paramagnetic metal co balt atoms. Herein the relation betweentheir magnetic characteriZation and molecular structure is discussed.

Key words: Cobalt compounds[Co₃(SS)₃(PR₃)₃], Magnetic susceptibility, ¹H NMR
