Trimethylphosphoniumtrans-tetrachloridobis(trimethylphosphane-κP)iridate(III)

Abstract

The title compound, [HP(CH3)3][IrCl4{(H3C)3P}2], consists of a trimethylphosphonium cation and a tetrachloridobis(trimethylphosphane)iridate(III) anion. The anion has an octahedral arrangement of ligands, with the trimethylphosphane groups occupyingtranspositions. The IrIIIatom sits on an inversion center with one P(CH3)3ligand and two chloride ligands in the asymmetric unit. The trimethylphosphonium cation is disordered about a twofold rotation axis. The title compound is the first structurally characterized tetrachloridobis(phosphane)iridate complex.
