Synthesis and molecular structure of hexanuclear organotitanium ion complex: [Cp6′Ti6(μ3-O)8][C2B10H10(μ-S2)2C2B9H10]2

The reaction of bis[(2-methoxyethyl)cyclopentadienyl] titanium dichloride with dilithium dithiolato carborane in THF give a novel hexanuclear organotitanium ion complex [Cp6′Ti6(μ3-O)8][C2B10H10(μ-S2)2C2B9H10]2 (Cp′ = C5H4CH2CH2OCH3) ([1][2]2) as yellow crystal blocks. The cation [1]2+ has an octahedral metallic skeleton of six titanium atoms with the tricoordinated oxygen (μ3-O) and the anion [2]− consists of two S2 bridged 7,8-dicarbaundecaborate cluster and 1,2-dicarba-closo-dodecaborate cluster.
