The structures of mono(glycinato)copper(II) and tris(glycinato)cuprate(II) complexes in solution were determined by means of X-ray diffraction at 20 degree C. The radial distribution curve obtained for solution A, in which comparable amounts of hexaaqua- and mono(glycinato)copper(II) complexes coexisted (the mole ratio C//g//l//y/C//C//u equals 0. 700, where C//i represents the total concentration of species i), showed that the mono(glycinato)copper(II) complex combined with four water molecules, two of which were at the distance of (1. 98 plus or minus 0. 01) A at the equatorial position and the other two were of (2. 27 plus or minus 0. 01) A at the axial one.
