• A series of complexes or geometrical isomers, [Co(β-ala or gly)(en)<SUB>2</SUB>]<SUP>2+</SUP>, [Co(β-ala or gly)<SUB>2</SUB>(en)]<SUP>+</SUP>, [Co(β-ala or gly)(ox)<SUB>2</SUB>]<SUP>2−</SUP>, and [Co(β-ala or gly)<SUB>2</SUB>(ox)]<SUP>−</SUP>, were prepared and their <SUP>13</SUP>C NMR spectra were measured. Assignments of their structures and <SUP>13</SUP>C NMR signals were made. The β-alaninate carbons in the complexes resonate at 33.6±0.5, 38.3±0.6, and 183.0±1.5 ppm and the glycinate carbons at 46.3±1.3 and 187.4±1.4 ppm. The <SUP>13</SUP>C chemical shifts of the mixed (β-alaninato)(glycinato) complexes consist of those of the corresponding isomers of bis(β-alaninato) and bis(glycinato) complexes.
