Abstract

Two different tetrahydrofuran adducts of lithium pentachlorozirconate(IV) were isolated in a reaction between diphenylamidolithium and zirconium(IV) chloride. The isolated complexes are [Li(thf)(4)][ZrCl5(thf)] (1), which decomposes at temperatures above -5 degrees C, and Li(thf)(3)-mu-Cl-ZrCl4 (thf) (2), which is thermally stable at 20 degrees C. Both complexes crystallise in the monoclinic space group No. 14. The complexes share similar geometry and synthetic background. Both structures consist of an octahedral ZrCl5-(thf) unit and a tetrahedrally coordinated lithium ion. In 1 the lithium tetrahedron is a distorted Li(thf)(4)(+) unit, whereas in 2 the pseudo-tetrahedral coordination sphere around lithium comprises a bridging chloro ligand. The data sets were collected at 153 K (1), and 193 K (2).
