Abstract
New complexes of cobalt(II), nickel(II), and copper(II) bromides with 3-amino-4-ethoxycarbo- nylpyrazole (L) of the composition ML4Br2 · 2H2O (M = Co(II) and Ni(II)) and CuL2Br2 are synthesized. The compounds are studied by X-ray diffraction analysis (CIF files CCDC nos. 1006284 (I), 1006286 (II), and 1006285 (III)), IR spectroscopy, and static magnetic susceptibility. In the complexes, the metal ions are in the distorted octahedral environment and the ligand is coordinated to the metal by the N(2) atom of the pyrazole cycle according to the monodentate mode. The Co(II) and Ni(II) complexes are mononuclear, whereas CuL2Br2 is polynuclear due to the bridging function of the bromide ion. Complex CuL2Br2 possesses the thermochromic properties: the transition of the color is brown (at room temperature) ⇔ light brown (at the temperature of liquid nitrogen).
