Geometrical aspects in coordination of an amino alcoholic ligand toward copper bromide

In the Article a new ionic complex of the copper(ІІ), [Cu(L)Br]Br, with 2-(2-(2-hydroxyethylamino)ethylamino)cyclohexanol (L) was prepared and identified by elemental analysis, FT-IR spectroscopy and single-crystal X-Ray diffraction. The spectroscopies data revealed that the ligand acts as NN OO-donor mode toward Copper atom and in agree with the structural analysis result. In this structure, the copper atom has a CuN2O2Br environment and distorted square pyramidal geometry. The ligand has a one chiral carbon atom whilst two new chiral centers (nitrogen atoms of the amine groups) are formed after coordination. In the crystal network of the complex, there are intermolecular N–H···X and O–H···X (X: Br) hydrogen bonds, extending the crystal network in three directions
