Abstract
The first structurally characterised titanium and iron polynuclear isopropoxides [FeCl{Ti2(OPri)9}], 1, and [Ti3(OMe)2(OPri)9][Fe4TiCl4(O)(OPri)9], 2, have been prepared from 2 : 1 : 1 mixtures of [Ti(OPri)4], K(OPri) and FeCl2. Their identity was confirmed by a number of chemical and physical methods including X-ray diffractometry. Semiempirical quantum mechanical calculations were consistent with an S=2 ground state for 1. Structural and spectroscopic data support a mixed-valence formulation for the unique {Fe4Ti} anion in 2.This publication has 1 reference indexed in Scilit:
