Crystal structure of chlorido(2-{1-[2-(4-chlorophenyl)hydrazin-1-ylidene-κN]ethyl}pyridine-κN)(η5-pentamethylcyclopentadienyl)rhodium(III) chloride
The title compound, [Rh(η5-C5Me5)Cl(C13H12ClN3)]Cl, is chiral at the metal and crystallizes as a racemate. Upon coordination, the hydrazinylidenepyridine ligand is non-planar, an angle of 54.42 (7)° being observed between the pyridine ring and the aromatic ring of the [2-(4-chlorophenyl)hydrazin-1-ylidene]ethyl group.
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(η5-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinylidenepyridine ligand isN,N-coordinated through theN-pyridyl andN-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.
