| Abstract: | Nitric oxide reacts with Co(PSR)2](BF4)2 (PSR 1-(thioalkyl)-2-(diphenylphosphino)ethane) to form five-coordinate mononitrosyl {CoNO}8 complexes. On the basis of infrared and NMR data the Co(NO)(PSR)2]2+ cations are believed to have a trigonal–bipyramidal geometry, with a linear Co–NO linkage. The mononitrosyl derivatives disproportionate in solution giving Co(NO)2(PSR)2]+ species, and probably Co(III) compounds. The stoichiometry of this reaction was examined in different solvents and in the presence of added halide or pseudohalide ions by NMR and IR techniques. The cobalt(III) complex Co(NCS)2(PSEt)2]BF4 has been isolated and characterized. |
