Synthesis and Characterization of Amino Alcohol Complexes

Abstract

Thirty-eight amino alcohol complexes were prepared and analyzed in the mole ratios 1 ; 1, 1 ; 2 and 2 3 (M ; L). The IR spectra proved that coordination occurs via oxygen nitrogen atoms of the ligands. The nujol mull electronic absorption spectra and the room temperature magnetic moment values proved that the complexes are of O h and T d geometry. All complexes, except those of Zn II , Cd II and Hg II are high spin with the existence of a Cu-Cu interaction in the copper complexes. The ESR parameters are calculated including the c-bond parameter ( f 2 ) and the fraction of 3 d character in the Cu II 3 d -4S ground state ( f 2 ) of the axial compressed triethanolamine complexes.
