Structural characterization of two large bismuth–cobalt carbonyl clusters: (PPN)2[Bi4Co9(CO)8(µ-CO)8]·2THF and (PPN)2[Bi8Co14(CO)12(µ-CO)8]·1.08THF

Abstract

The reaction of PPN[Bi2Co4(CO)10(µ-CO)] with Mo(CO)3(toluene) in THF yields, after slow oxidation, the large clusters, (PPN)2[Bi4Co9(CO)8(µ-CO)8] and (PPN)2[Bi8Co14(CO)12(µ-CO)8][PPN = bis(triphenylphosphine)iminium] which exhibit close-packed arrays of main group elements and transition metal atoms.
