Syntheses and structures of two anion-templated dinuclear cadmium complexes with diamino-binaphthyl Schiff bases as ligands

Two cadmium(II) complexes, [CdL1Cl2]2 · 2CH3OH and [CdL2(SCN)2]2 · CH3OH (1 and 2), were prepared by mixing 2,2′-diamino-1,1′-binaphthalene and 2-pyridyl-carboxaldehyde in the presence of two different cadmium(II) salts. The Schiff base ligand appeared in complex 1 has only one imine group, while in complex 2 both amino groups were reacted to form two imine groups.
