| Abstract: | Hsalea (N-(2-hydroxybenzyl)-2-amino-1-ethanol) and its Cu(II) complexes, Cu(salea)2 (1) and CuH−1(salea)·1.5H2O (2), were prepared and characterized. X-ray structural analyses of 1 show that two amino N and two deprotonated phenoxy O atoms of the two ligands coordinate equatorially to Cu(II). Two alcoholic O atoms coordinate weakly at axial positions. Each molecule utilizes two alcoholic H atoms and two phenoxy O atoms to form hydrogen bonds with four surrounding molecules, leading to a two-dimensional network structure. EPR and electronic spectra of 1 are consistent with the elongated octahedral coordination polyhedron. |
