Studies on Synthesis, Structure and Properties of Cobalt Complex [Co(Ⅰ) (dppe)2CO]2[Co2(Ⅱ) (dppe)Cl6O2]

Abstract

Abstract: Acobalt complex with mixed valence state [Co(Ⅰ) (dppe)₂CO]₂ [Co₂ (Ⅱ)(dppe) Cl]₆O₂] (dppe=1,2 -bis(diphenylphosphino) ethane) has been prepared. The compound crystallizes in triclinic space group P1 with unit cell parameters: a=1.1763(3)nm, b=1.2943(6)nm, c=2.1507(9)nm, a=81.44(4)°,β=82.58(3)°, r=79.82(3)°, V=3.1691nm³ and Z=1. The structure was solved by direct method according to ALPHAcriterion and was refined by a block diagonal matrix least-squares procedure to final R= 0.084, Moreover, infared spectra, electronic reflection spectra and cyclic voltammetry curve were mearsured.

Key words: Cobalt, Synthesis, Structure and properties
