Abstract

Potassium trans(N)-(C-methyl substituted ammoniatriacetato)(β-alaninato)cobaltate(III) have been prepared, where C-methyl substituted ammoniatriacetates are (S)-alaninate-N,N-diacetate and (R,S)- or (S,S)-alaninate-N-isopropionate-N-acetate. Some of the possible isomers concerning the arrangement of three feet of the tripod-like quadridentate ligand have been isolated and assigned structurally on the basis of the nuclear magnetic resonance spectra and isomerization experiments.
