Multinuclear 3d-4f complexes with sandwichlike molecular structures are formed with the Schiff-base ligand bis-(3-methoxysalicylidene)ethylene-1,2- phenylenediamine(H2L). The stoichiometry and structures are dependent on the Zn:Nd ratio and counteranions present. They are trinuclear [Nd(ZnL) 2(NO3)2(H2O)2] ·NO3·EtOH·H2O (1), [Nd-(ZnL) 2Cl2(H2O)3] ·Cl·2MeOH·5H2O (2), and tetranuclear [Nd 2(ZnL)2Cl6(MeOH)2]·MeOH (3). Dinuclear complex [NdZnL-(NO3)3MeCN]·MeCN (4) was also characterized. Near-infrared (NIR) lanthanide luminescence is observed in these complexes.
