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.

The crystalline phases of the trans-(a) and cis-(b)-isomers of bis-(α-amino acids) copper(II) complexes [Cu(bL)2] 1–5 (bL - bidentate ligand: gly (1), S-ala (2), R,S-val (3), (±)-thr (4), R,S-phe (5)) were studied by ATR-FTIR spectroscopy in the mid region IR spectrum. It was established that asymmetric νas(COO) and symmetric νs(COO) stretching vibrations of carboxylic groups of 1–5 are sensitive to change of the geometric structure and have a different maxima for the trans(a)- and cis(b)-isomers. It found that νas(COO) and νs(COO) stretching vibrations of cis-isomers are broadened and shifted to longer wavelengths (b) as compared with trans-isomers (a). Shown that peculiarities of crystal packing molecules of geometric isomers may affect on carboxylate stretching vibration bis-α-amino acids complexes copper(II) 1–5 a,b.

, p. 2700 - 2706 (2020/11/23)
In this work, a simple and low cost synthetic method for four different copper nanomaterials having uniform shape and size using copper(II) acetate and cis-bis(glycinato)copper(II) complex in presence of non-ionic surfactants Tween-80 and Triton X-100 in the presence of ascorbic acid as reducing agent is described. The synthesized nanomaterials were characterized using FT-IR, UV-visible, powder XRD, EDX and SEM techniques. The characterization data reveals that all the copper nanomaterials formed are less than 30 nm size with spherical shape.

, p. 115 - 119 (2008/10/08)
The two solid-state coordination reactions CuAc2·H2O(s) + 2Ala(s) → trans-Cu(Ala)2(s) + 2HAc(1) + H2O(1) (1) CuAc2·H2O(s) + 2Gly(s) → trans-Cu(Gly)2·H2O(s) + 2HAc(1) (2) have been studied by solution calorimetry. The molar dissolution enthalpies of the reactants and the products in some solvents (such as 2 mol 1-1 HCl or its solutions) of these solid-solid coordination reactions have been measured by an isoperibol solution calorimeter. The standard molar formation enthalpies of [trans-Cu(Ala)2(s), 298.15 K] and [trans-Cu(Gly)2(s), 298.15 K] have been determined to be - 1015.42 ± 0.06 and 1252.36 ± 0.05 kJ mol-1, respectively, from the results of the molar dissolution enthalpies and other auxiliary thermodynamic data.
