Abstract
Based on the consideration of crystal structures of three diastereomeric salts composed of the tris(ethylenediamine)metal complex and the d-tartrate anion, an attempt was made to resolve tris(β-alaninato)cobalt(III) by the chromatographic technique, and a complete resolution was achieved through a Sephadex column using sodium d-tartrate 30% aqueous ethanol solution as an eluent.
