The compounds HOs/sub 3/(..mu../sub 3/-S)(..mu..-HC double bond NR)(CO)/sub 9/, Ia, R = C/sub 6/H/sub 5/, and Ia', R = C/sub 6/H/sub 4/-p-F, lose CO and/or H/sub 2/ when heated to form the hexanuclear osmium complexes Os/sub 6/(..mu../sub 4/-S)(..mu..-HC double bond NR)/sub 2/(CO)/sub 18/, IIa, R = C/sub 6/H/sub 5/, and IIa', R = C/sub 6/H/sub 4/-p-F, H/sub 2/Os/sub 6/(..mu../sub 4/-S)(..mu../sub 3/-S)(..mu..-HC double bond NR)/sub 2/(CO)/sub 17/, IIIa,b, R = C/sub 6/H/sub 5/, and IIIa',b', R = C/sub 6/H/sub 4/-p-F, which exist as two isomers, H/sub 2/Os/sub 6/(..mu../sub 4/-S)(..mu../sub 3/-S)(..mu..-HC double bond NR)/sub 2/(CO)/sub 16/, IVa-c, R = C/sub 6/H/sub 5/, and IVa'-c', R = C/sub 6/H/sub 4/-p-F, which exist as three isomers, and Os/sub 6/(..mu../sub 4/-S)/sub 2/(..mu..-HC double bond NR)/sub 2/(CO)/sub 15/, Va, R = C/sub 6/H/sub 5/, and Va', R = C/sub 6/H/sub 4/-p-F. All compounds have been analyzed by ir and /sub 1/H NMR spectroscopy. Compounds IIIa', IVa and Va have also been characterized by single-crystal x-ray diffraction analyses. Compounds III can be converted to IV, and IV into V. III, IV, and V are believed to be part of a sequence of cluster growth processes in which the sulfido ligands mediate the initial linking of the clusters and the subsequent formation of metal-metal bonds between them. IIIa' contains two open triangular groups of three metal atoms linked by a tetrahedrally coordinated sulfido ligand. In IVa the six metal atoms are arranged in groups of four and two, with the two groups linked by a tetrahedrally coordinated sulfido ligand. In Va the six metal atoms have condensed into a central cluster of four which has the form of a butterfly tetrahedron with sulfido ligands bridging the two open triangular faces. The two remaining metal atoms are bonded to the hinge metal atoms of the central cluster, one to each.
