title: Crystal structure of chlorido-(2-{[2-(4-chloro-phen-yl)hydrazin-1-yl-idene-κN (1)](phen-yl)meth-yl}pyridine-κN)(η(5)-penta-methyl-cyclo-penta-dien-yl)iridium(III) tetra-phenyl-borate.
abstract: The title compound, [Ir(η(5)-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinyl-idene-pyridine ligand is N,N-coordinated through the N-pyridyl and N-hydrazinyl-idene groups forming a five-membered metallacycle. An intra-molecular C-H⋯Cl hydrogen bond is observed. In the crystal, centrosymmetrically-related cations are connected by C-Cl⋯π inter-actions, forming a dimeric structure. The crystal packing is further stabilized by weak inter-ionic C-H⋯π inter-actions.
