THE ISOLATION OF TRANS AND CIS ISOMERS OF DICARBONATOBIS(PYRIDINE)COBALTATE(III)

Autor: Muraji Shibata, Kazuhiro Kobayashi, Yayoi Ida

Publikováno v: Chemistry Letters. 3:1299-1302

Two isomeric compounds, trans- and cis-K[Co(CO3)2(py)2]·3H2O, have been isolated from a reaction mixture of the [Co(CO3)3]3− ion with pyridine. The absorption spectrum of the trans complex revealed distinct splitting of the second absorption band.

Synthesis and Absorption Spectra of the [Co(O–O)2(py)2]-type Complexes

Autor: Shuhei Fujinami, Yayoi Ida, Muraji Shibata

Publikováno v: Bulletin of the Chemical Society of Japan. 50:2665-2671

Five bis (dicarboxylato)bis(pyridine)-type complexes, trans-[CoCO3ox(py)2]−, trans- and cis-[Co(ox)2(py)2]−, and trans- and cis-[Co(mal)2(py)2]−, have been isolated as crystals and characterized on the basis of the absorption spectra, the PMR s

The Preparation of 2,2′-Bipyridinedicarbonato and Dicarbonato-1,10-phenanthroline Complexes of Cobalt(III)

Autor: Muraji Shibata, Kiyoyuki Imai, Yayoi Ida

Publikováno v: Bulletin of the Chemical Society of Japan. 51:2741-2742

Two new dicarbonato complexes, K[Co(CO3)2(bpy)]·2H2O and K[Co(CO3)2(phen)]·H2O, have been prepared by the method starting from the [Co(Co3)3]3− complex and resolved by means of diastereoisomer formation.
