Abstract
- Metalladichalcogenolate cluster complexes [Cpâ²Co{E2C2(B10H10)}]{Co2(CO)5} [Cpâ² = η5-C5H5, E = S(3a), E = Se(3b); Cpâ² = η5-C5(CH3)5, E = S(4a), E = Se(4b)], {CpCo[E2C2(B10H10)]}2Mo(CO)2] [E = S(5a), Se(5b)], Cp*Co(µ2-CO)Mo(CO)(py)2[E2C2(B10H10)] [E = S(6a), Se(6b)], Cp*Co[E2C2(B10H10)]Mo(CO)2[E2C2(B10H10)] [E = S(7a), Se(7b)], (Cpâ²Co[E2C2(B10H10)]W(CO)2 [E2C2(B10H10)] [Cpâ² = η5-C5H5, E = S(8a), E = Se(8b); Cpâ² = η5-C5(CH3)5, E = S(9a), E = Se(9b)], {CpCo[E2C2(B10H10)]}2Ni [E = S(10a), Se(10b)] and 3,4-(PhCN4S)-3,1,2-[PhCN4SCo(Cp)S2]-3,1,2-CoC2B9H812 were synthesized by the reaction of [Cpâ²CoE2C2(B10H10)] [Cpâ² = η5-C5H5, E = S(1a), E = Se(1b); Cpâ² = η5-C5(CH3)5, E = S(2a), E = Se(2b)] with Co2(CO)8, M(CO)3(py)3 (M = Mo, W), Ni(COD)2, [Rh(COD)Cl]2, and LiSCN4Ph respectively. Their spectrum analyses and crystal structures were investigated. In this series of multinuclear complexes, 3a,b and 4a,b contain a closed Co3 triangular geometry, while in complexes 5aâ7b three different structures were obtained, the tungstenâcobalt mixed-metal complexes have only the binuclear structure, and the nickelâcobalt complexes were obtained in the trinuclear form. A novel structure was found in metallacarborane complex 12, with a BâS bond formed at the B(7) site. The molecular structures of 4a, 5a, 6a, 7b, 9a, 9b, 10a and 12 have been determined by X-ray crystallography. [ABSTRACT FROM AUTHOR]
