Chlorido[1-(2-oxidophenyl)ethylidene][tris(3,5-dimethylpyrazol-1-yl) hydroborato]iridium(III) chloroform monosolvate

Abstract

In the title compound, [Ir(C15H22BN6)(C8H7O)Cl]·CHCl3, the Ir atom is formally trivalent and is coordinated in a slightly distorted octahedral geometry by three facial N atoms, one C atom, one O atom and one Cl atom. The Ir Ccarbene bond is strong and short and exerts a notable effect on the trans-Ir—N bond, which is about 0.10 A˚ longer than the two other Ir—N bonds. The chloroform solvent molecule is anchored via a weak C—H·· ·Cl hydrogen bond to the Cl atom of the Ir complex molecule. In the crystal, the constituents adopt a layer-like arrangement parallel to (010) and are held together by weak intermolecular C—H·· ·Cl hydrogen bonds, as well as weak Cl·· ·Cl [3.498 (2) A˚ ] and Cl·· ·JT [3.360 (4) A˚ ] inter- actions. A weak intramolecular C—H·· ·O hydrogen bond is also observed
