The 16-electron half-sandwich iridium complexes [Cp*IrE2C2(B10H10)}] [E = S (1a), Se (1b)] (Cp* = eta(5)-C5Me5) [Cp*Ir[E2C2(B10H10)] = eta(5)-pentamethylcyclopentadienyl-[1,2-dicarbacloso-dodecaborane(12)-dichalcogenolato]iridium] reacted with Co-2(CO)(8) in toluene solution to afford the trinuclear clusters [Cp*IrE2C2(B10H10)}]Co-2(CO)(5)} [E = S (2a), Se (2b)] and mononuclear complexes [Cp*Ir(CO)E2C2(B10H10)}] [E = S (3a), Se (3b)] as byproducts. Compounds 2a and 2b contain closed IrCo2 triangle geometry with one Co-Co and two Ir-Co bonds. The dinuclear IrFe complexes [Cp*IrE2C2(B10H10)}]Fe(CO)(3)} [E = S (4a), Se (4b)] were obtained from the reactions of 1a and 1b with Fe(CO)5 in the presence of Me3NO. The molecular structures of 2a, 2b, and 4b have been determined by X-ray crystallography.

A hetero-metallic cluster Cp*Ir[S2C2(B10H10)]}(2)Mo(CO)(2) (2) has been synthesized and structurally characterized, and their thirdorder nonlinear optical (NLO) properties have been investigated by Z-scan technique. The results indicate that 2 exhibit good NLO absorption and self-focusing effects. The hyperpolarizability gamma value is calculated to be 2.60 x 10(-29) esu for 2. (c) 2007 Elsevier B.V.
