New transition metal binding modes for creatinine: molecular structures of [(C4R4)Ir(C4H7N3O)(PPh3)2Cl] and [(C4R4)Ir(C4H7N3O)(PPh3)2]BF4, (R = CO2CH3)
TL;DR: In this paper, X-ray crystallography established two unprecedented coordination modes for creatine in complexes 6 and 7, where the creatinine is bound to iridium in a monodentate fashion through the exocyclic nitrogen, whereas the iridium serves as a bidentate η 2 -(N,O)-ligand in 7.

Organometallic compounds containing a guanidinium group. Phenylmercury(II) derivatives of creatine and creatinine
Abstract: Phenylmercury(II) replaces a proton of creatine, H2NC+(NH2)NMeCH2C02-, in basic solution to form the zwitterionic
complex PhHgNHC+(NH2)NMeCH2CO2-. Creatine and creatinine (C4H7N30) react with PhHg((OH)N03)I/2 in aqueous ethanol to form a 2:l complex [(PhHg)2(C4H6N30][N03] which exists in two crystalline forms. Creatinine forms a 1:l
complex [PhHg(C4H7N30)][N03].1/2H20 at pH 1.4 on reaction with PhHg((OH)N03)l/2 in the presence of nitric acid.
The 1:l and 2:l complexes may be interconverted. Creatinine hydronitrate, [H2NCNMeCH2CONH][NO3], and the PhHg(II) complexes of creatinine have similar infrared (including deuterated derivatives) and 1H NMR spectra, consistent with retention of the creatinine ring and presence of a guanidinium group in the complexes. An X-ray structural analysis of one crystalline form of the 2:l complex shows bonding of PhHg(II) groups to the exocyclic and ring nitrogens of creatinine to form the cation
[PhHgNHCNMeCH2CONHgPh]+.
