Crystal Structure of Tri-μ-chloro-bis[(1,2,3,4,5-η)-1,2,3,4,5-pentamethyl-2,4-cyclopentadien-1-yl)]-diiridium Tetrafluoroborate with a Unique Trigonal-bipyramidal Ir₂Cl₃ Core, [Ir₂(Cp^*)₂(μ-Cl)₃]BF₄ (Cp^* =η⁵-C₅Me₅)

Abstract

Colorless single crystals of a dinuclear Ir complex, [Ir₂(Cp^*)₂(μ-Cl)₃]BF₄ (Cp^* = η⁵-C₅Me₅), were obtained with a reaction of [Ir(Cp^*)(Me₂CO)₃]²⁺ and triptycene under Ar. The crystal structure was determined using CCD single crystal XRD data. The two Ir atoms are μ₂-bridged by three chloride atoms to provide a dinuclear structure with a unique trigonal-bipyramidal Ir₂Cl₃ core.
