New condensed amino acids were observed in two Cu(II) complexes, both involving guanidinoacetic acid (GAA). The copper(II) complexes, 1 and 2, were synthesized and characterized by X-ray crystallography and infrared spectroscopy. Vibrational assignme

The title compound, K[Co(C4H4NO4)2]3.5H2O, is a by-product resulting from adventitious oxidation, in the presence of racemic aspartic acid, of cobalt(II) in a cobaltous starting material. The presence of both enantiomeric forms of the tridentate as
