Abstract

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.
