Synthesis,crystalstructure ad EPR of a hydrogen bonded two-dimensional network of Cu(II0 complex with N-(2-hydroxybenzyl)-2-amino-1-ethanol

摘要

Hsalea (N-(2-hydroxybenzyl)-2-amino-1-ethanol) and its Cu(II) complexes. Cu(salea)2 (1) and CuH — (salea)] .5H.O (2). were prepared and characterized. X-ray structural analyses of 1 show that two amino N and two deprotonated phenoxy 0 atoms of the two ligands coordinate equatorially to Cu(II). Two alcoholic 0 atoms coordinate weakly at axial positions. Each molecule utilizes two alcoholic H atoms and two phenoxy 0 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.
