Crystal structure of chlorido(2-{[2-(4-chlorophenyl)hydrazin-1-ylidene-κN¹](phenyl)methyl}pyridine-κN)(η⁵-pentamethylcyclopentadienyl)iridium(III) tetraphenylborate

Abstract

The title compound, [Ir(η5-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinyl­idene­pyridine ligand is N,N-coordinated through the N-pyridyl and N-hydrazinyl­idene groups forming a five-membered metallacycle. An intra­molecular C—H⋯Cl hydrogen bond is observed. In the crystal, centrosymmetrically-related cations are connected by C—Cl⋯π inter­actions, forming a dimeric structure. The crystal packing is further stabilized by weak inter­ionic C—H⋯π inter­actions.
