A structural study on the cubic crystalline modification of [Cp₆Ti₆O₈][Bu₃Sn₃S₃(SH)₃Cl]₂

Abstract

Crystal and molecular structures of a cubic crystalline form of [Cp₆Ti₆O₈][Bu₃Sn₃S₃(SH)₃Cl]₂have been studied by single crystal X-ray diffraction. The cation, [Cp₆Ti₆O₈]²⁺is a cluster comprising an octahedron with six Ti(IV) atoms at the vertices. Each of the eight faces is capped by an oxygen atom. The cluster is electron deficient as it possesses 84 electrons only. The anion is a six membered ring (with alternated Sn and S atoms) having a chair conformation. The crystal undergoes a phase transition on cooling which has been monitored by X-ray diffraction studies.
