Abstract On the basis of the localized molecular orbital (LMO) theory, the bonding schemes for the following types of cluster compounds are briefly reviewed in this paper; the linear [Et4N][Cl2FeS2MoS2Cu(PPh3)2] cluster, triangular trinuclear [M 3(μ3−X)(μ−Y 3]4+ (M = Mo, W;X = O, S;Y = O, S, Se) clusters, triangulated polyhedral clusters: closo-boranes B n H n 2−, octahedral [Co6(CO)14]4−, [Ni2Co4(CO)14]2− and [Co6(μ3 −X 8 ·L 6 n+ (X = S, Se;L = PPh3, PEt3, CO;n = 0,1) as well as quasi-aromatic cluster ligands in cubane-type [Mo3S4 ·ML n (4 +q) + (M = Mo, W, Fe, Ni, Cu, Sn, Sb;L = Ligand and sandwich-type [Mo3S4 ·M · S4Mo3]8+ (M = Mo, Sn, Hg). We put emphasis upon the characteristics of multicentered bonding in these cluster molecules, and, especially, point out existence of a novel species of quasi-aromatic cluster compounds.
