Spectral characteristics and structures of metal complexes with 3-hydroxy-4,6-dinitro-2-ethoxypyridine: Crystal and molecular structures of di(3-hydroxy-4,6-dinitro-2-ethoxypyridinato)diaquacopper(II)

Seven complexes of manganese(II), copper(II), cadmium, silver(I), samarium(III), and praseodymium( III) with 3-hydroxy-4,6-dinitro-2- ethoxypyridine (HL) were isolated in the crystalline state and studied by IR and UV spectroscopy. The molecular and crystal structures of di(3-hydroxy-4,6- dinitro-2-ethoxypyridinato) diaquacopper(II) [CuL2(H 2O)2] were determined. The coordination mode of the organic ligand L- is bidentate chelating through the O(2) oxygen atoms of the hydroxy group and the O(1) atom of the ethoxy group. The coordination polyhedron of the copper atom is a prolate tetragonal bipyramid (4 + 2) with two O(1) atoms in the axial positions (Cu-O(1) 2.413 Å) and two O(2) atoms of the two L-ligands and the O(7) atoms of the water molecules in the equatorial plane (Cu-O(2), 1.912 Å; Cu-O(7), 1.972 Å). © 2008 Pleiades Publishing, Ltd.
