Abstract New mixed-ligands complexes with empirical formulae: M (2, 4′-bpy) 2 L 2· H 2 O (M (II) Zn, Cd), Zn (2-bpy) 3 L 2· 4H 2 O, Cd (2-bpy) 2 L 2· 3H 2 O, M (phen) L 2· 2H 2 O (where M (II)= Mn, Ni, Zn, Cd; 2, 4′-bpy= 2, 4′-bipyridine, 2-bpy= 2, 2′-bipyridine, phen= 1, 10-phenanthroline, L= HCOO−) were prepared in pure solid state. They were characterized by chemical, thermal and X-ray powder diffraction analysis, IR spectroscopy ...
