Abstract
Compounds with the general formula CpMS4MCp display a remarkable variety in structure. By a detailed theoretical analysis of this class of complexes and related compounds such as NbX2Y6(X=Se,Te; Y=Br,I) or CpV(S2)S2VCp, we are able to explain how the central S4 unit traverses in many compounds a range in S-S bonding from a ring to isolated sulfide bridges. The isomer CpMo(S2)2MoCp can undergo a symmetry-allowed transformation to form CpMo(S)S2(S)MoCp. The bonding in the molecular compounds is compared to that in their solid-state analogues NbX2Y6. As in acetylene complexes, S2 groups can enter the compounds under study in a parallel and a perpendicular orientation. The latter one is energetically preferred. The rearrangement of parallel-and perpendicular-oriented S2 groups is symmetry forbidden.
