USE OF TL(C5H5) FOR THE SYNTHESIS OF IN(C5H5)(3-N)X(N) - CRYSTAL-STRUCTURE OF [IN(C5H5)CL-2(O(CH2CH2)(2))(2)]

Reaction of thallium(I) cyclopentadienide with InCl3 and InI3 led to t he stepwise replacement of halide ions by cyclopentadienides. The comp lex [In(C5H5)Cl-2 {O(CH2CH2)(2)}(2)] was isolated and its solid-state structure was established by single-crystal X-ray diffraction. In this pentacoordinated complex, the central indium(III) ion is bonded to tw o tetrahydrofuran molecules in the axial position, one cyclopentadieni de ligand and two chloride ions in the equatorial positions in a trigo nal bipyramidal arrangement.
