THE CRYSTAL AND MOLECULAR-STRUCTURE OF [BIS(AQUO)-BIS(2-(METHYLAMINO)PYRIDINE)COPPER(II)] DICHLORIDE

Spectroscopic features of [bis(aquo)bis(2-aminomethylpyridine)copper(I I)] dichloride, [Cu(ampy)(2)(H2O)(2)]Cl-2, are presented and its X-ray crystal structure is described. The IR spectra, ligand field spectra and conductivity measurements confirmed that the chloride anions were not coordinated to the metal ion. The copper(II) cation is coordinated by two water and two bidentate 2-aminomethylpyridine molecules. The c hloride anions are rather strongly hydrogen-bonded to two hydrogen ato ms of water molecules and two hydrogen atoms of the primary amino grou p in a distorted tetrahedral arrangement.
