Di-μ-hydroxo-κ⁴O:O-bis[aquatris(triphenylsilanolato-κO)zirconium(IV)] toluene solvate

Abstract

The title compound, [Zr2(C18H15OSi)6(OH)2(H2O)2]·C7H8, is a dimeric ZrIV compound. The asymmetric unit consists of two half‐molecules of the complex and a toluene solvent mol­ecule. The zirconium centres are bridged by two μ‐hydroxo ligands. Each Zr is octa­hedrally coordinated by the hydroxo groups, three triphenyl­silanolato groups and an additional water ligand. The centres of both Zr2O2 rings are located on crystallographic centres of inversion. The two independent monomeric units differ significantly with respect to the Zr—O—Si bond angles which is most probably due to the high steric demands of three triphenyl­silanolato ligands.
