A compound of the type Cu(Hippu) 2 · H 2 O has been prepared, where Hippu is N‐benzoylglycine (hippuric acid). Amine adducts of the type Cu(Hippu) 2 B (B = piperazine (pz), 2,2′‐bipyridine (bipy) and 1, 10‐phenantroline (phen)) and Cu(Hippu) 2 B 2 (B = N‐methylpiperazine (CH 3 ‐pz), piperidine (pd), morpholine (mf), pyridine (py) and ethylenediamine (en)) were obtained by reaction of the amines with Cu(Hippu) 2 · 4 H 2 O. Each complex was characterized by elemental analysis, infrared spectrum, electronic spectrum and magnetic moment. For each base adduct the coordination of the amino acid occurs only through terminal carboxyl oxygen in a monodentate or monodentate‐bridging arrangement. In the case of the base adducts of piperidine and ethylenediamine, a square‐planar pattern of coordination about the copper(II) ion is supported by their electronic spectra. While those of piperazine, N‐methylpiperazine, 2,2′‐bipyridine, morpholine, pyridine and 1, 10‐phenantroline adducts indicate a pentacoordinate environment.
