Abstract

Abstract The reaction of bis[(2-methoxyethyl)cyclopentadienyl] titanium dichloride with dilithium dithiolato carborane in THF give a novel hexanuclear organotitanium ion complex [ Cp 6 ′ Ti 6 ( μ 3 -O ) 8 ] [ C 2 B 10 H 10 ( μ - S 2 ) 2 C 2 B 9 H 10 ] 2 (Cp′ = C 5H 4CH 2CH 2OCH 3) ([ 1][ 2] 2) as yellow crystal blocks. The cation [ 1] 2+ has an octahedral metallic skeleton of six titanium atoms with the tricoordinated oxygen (μ 3-O) and the anion [ 2] − consists of two S 2 bridged 7,8-dicarbaundecaborate cluster and 1,2-dicarba- closo-dodecaborate cluster.
