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

The title compound, [Ir(eta(5)-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 center dot center dot center dot Cl hydrogen bond is observed. In the crystal, centrosymmetrically- related cations are connected by C-Cl center dot center dot center dot pi interactions, forming a dimeric structure. The crystal packing is further stabilized by weak interionic C-H center dot center dot center dot pi interactions.
