✦ Synopsis

The halogen oxidation and nitrosylation of cis-E(SB)M-(CO)4] I-M = Cr or Mo, SB = N,N'-ethylenebis(p-tolualideneimine), N,N'-ethylenebis(p-N,N-dimethylaminobenzalideneimine) or N,N'-ethylenebis(methyl-p-methoxyphenylketimine); M = Mo, SB = N,N'-ethylenebis-(cinnamylideneimine) or N,N'-ethylenebis(methyl-p-methylphenylketimine)] have been studied. Halogenation of I-(SB)Cr(CO)4 ] yielded [(SB)CrX2] (X = C1, Br or I) whereas [(SB)Mo(CO)4] gave [(SB)Mo(CO)3X2] (X = Br or I) and [(SB)MoX,] (X = I, n = 2; X = C1 or Br, n = 4). NOC1 produced [(SB)Cr(NO)2C12] and [(SB)Mo(CO)2(NO)C1 ] when reacted with the corresponding [(SB)M(CO)4 ]. The complexes were characterized by physico-chemical and spectroscopic measurements.
