Synthesis and Equilibrium Studies of Mixed‐Ligand Complexes of Co(II), Ni(II), and Cu(II) with Some Aliphatic Dicarboxylic Acids and Creatinine
TL;DR: In this article, the formation constants of binary and ternary mixed-ligand metal complexes were determined by pH-metric titrations at 25 −±−0.1°C and at a constant ionic strength I −= 0.1 −M (KNO3), respectively.
Journal ArticleDOI
New copper(II) complexes of Creatinine
TL;DR: In this paper, the synthesis and thermal behavior of new Cu(II)-Creatinine complexes are described by the coupled TG-FT-IR technique, and a parallel characterization by solid state IR spectroscopy and mass spectrometry is also reported.

Dimeric and oligomeric platinum(II, II), (II, III) and palladium(II, II) complexes with creatinine
TL;DR: In this paper, the structure and coordination mode of the ligand were studied by means of EPR, IR, TG and DTA methods and the results showed that by varying the reaction conditions (acidity, metal-to-ligand ratio, presence of oxygen), different platinum and palladium complexes are obtained.

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]+.
