Correlations of synthetic, spectroscopic, structural, and speciation studies in the biologically relevant Cobalt(II) - Citrate system: The tale of the first aqueous dinuclear Cobalt(II) - Citrate complex
Kotsakis, N.; Raptopoulou, C. P.; Tangoulis, V.; Terzis, A.; Giapintzakis, John; Jakusch, T.; Kiss, T.; Salifoglou, A. (2003)Synthetic efforts targeting soluble species of Co(II) with the low molecular mass physiological ligand citric acid led to the isolation of the first dinuclear complex [Co2(C6H5O7)2 (H2O)4]2-, at pH ∼5, in the form of its ...

Manganese citrate chemistry: Syntheses, spectroscopic studies, and structural characterizations of novel mononuclear, water-soluble manganese citrate complexes
Matzapetakis, M.; Karligiano, N.; Bino, A.; Dakanali, M.; Raptopoulou, C. P.; Tangoulis, V.; Terzis, A.; Giapintzakis, John; Salifoglou, A. (2000)The first two mononuclear manganese citrate complexes, (NH4)4[Mn(II)(C6H5O7)2] (1) and (NH4)5[Mn(III)(C6H4O7)2]·2H2O (2) were synthesized in aqueous solutions near physiological pH values. They were isolated in their pure ...

Synthesis and structural and spectroscopic characterization of a complex between Co(II) and imino-bis(methylphosphonic acid): Gaining insight into biologically relevant metal-ion phosphonate interactions or looking at a new Co(II)-organophosphonate material?
Jankovics, H.; Daskalakis, M.; Raptopoulou, C. P.; Terzis, A.; Tangoulis, V.; Giapintzakis, John; Kiss, T.; Salifoglou, A. (2002)Cobalt is an essential metal ion involved in key biomolecules, regulating processes in human physiology. As a metal ion, Co(II) assumes forms, which are dictated by the nature of organic binders in biological fluids, and ...

Synthesis, spectroscopic, and structural characterization of the first aqueous cobalt(II)-citrate complex: toward a potentially bioavailable form of cobalt in biologically relevant fluids
Matzapetakis, M.; Dakanali, M.; Raptopoulou, C. P.; Tangoulis, V.; Terzis, A.; Moon, N.; Giapintzakis, John; Salifoglou, A. (2000)Citric acid represents a class of carboxylic acids present in biological fluids and playing key roles in biochemical processes in bacteria and humans. Its ability to promote diverse coordination chemistries in aqueous ...

Vanadium(IV) - Citrate complex interconversions in aqueous solutions. A pH-dependent synthetic, structural, spectroscopic, and magnetic study
Tsaramyrsi, M.; Kaliva, M.; Salifoglou, A.; Raptopoulou, C. P.; Terzis, A.; Tangoulis, V.; Giapintzakis, John (2001)Citrate is abundantly encountered in biological fluids as a natural metal ion chelator. Vanadium participates in biological processes as a catalyst in the active sites of metalloenzymes, as a metabolic regulator, as a ...
