NEW ZINC OXALATO AND HYDROGENOXALATO COMPLEXES: SYNTHESIS AND INFRARED STUDY

Journal of Engineering Studies and Research, 2017
Five new oxalato and hydrogenoxalato complexes with ZnBr2 have been synthesized and studied by infrared. Discrete structures have been suggested in the basis of spectroscopic data.

DEARYLATION IN THE INTERACTIONS BETWEEN (Et3NH)HC2O4 OR (Et3NH)2C2O4 AND SnPh3Cl: INFRARED STUDY

Journal of Engineering Studies and Research, 2017
Five new oxalato, hydrogenoxalato and hydrogenocarbonato adducts (three) and complexes (two) obtained on allowing (Et3NH)HC2O4 or (Et3NH)2C2O4 to react with SnPh3Cl have been studied by infrared spectroscopy, then discrete structures suggested on the ...

ChemInform Abstract: KINETICS AND MECHANISM OF THE OXIDATION OF RUTHENIUM(II) AMMINES BY TETRAAMMINE(OXALATO)‐ AND PENTAAMMINE(HYDROGENOXALATO)COBALT(III) COMPLEXES

Chemischer Informationsdienst, 1982
AbstractDie gemäß einer 1:1‐St‐öchiometrie (Gleichung A) ablaufenden Oxidationsreaktionen von [Ru(NH3 )6 ]2 (I) und [Ru(NH3)5 OH, 12+ (II) mit [Co(NH3)4 (C204)? (III) und [Co(NH3 )5 (HC,O4)]′ (IV) werden bei einer Ionenstärke von 0.20 mol dm′3 (LiCl) in Abhängigkeit von der HCl‐Konzentration untersucht.

Notes. Kinetics and mechanism of the oxidation of ruthenium(II) ammines by tetra-ammine(oxalato)- and penta-ammine(hydrogenoxalato)-cobalt(III) complexes

Journal of the Chemical Society, Dalton Transactions, 1982
The oxidations of [Ru(NH3)6]2+ and [Ru(NH3)5(OH2)]2+ by [Co(NH3)4(C2O4)]+ and [Co(NH3)5(HC2O4)]2+ have been investigated at an ionic strength of 0.20 mol dm–3(LiCl) at various acid (HCl) concentrations. The oxidation of both ruthenium(II) species by [Co(NH3)4(C2O4)]+ is acid-independent whereas that by [Co(NH3)5(HC2O4)]2+ is acid-inhibited.
