Abstract

Solvent and reaction stoichiometry dictate the products isolated from reactions of the dinuclear precursor complex [ZnNdL(H₂O)(NO₃)₃] (H₂L = N,N′-bis(3-methoxy-salicylidene)ethylene-1,2-diamine) with the anionic multidentate linker 1,4-benzenedicarboxylate (1,4-BDC). With a 2:1 molar ratio of ZnNd:Na₂1,4-BDC in CH₃CN-EtOH the tetranuclear complex [Zn₂Nd₂L₂(1,4-BDC)(NO₃)₄(EtOH)₂] · 2MeCN (1) is produced while hexanuclear [Zn₄Nd₂L₄(1,4-BDC)₂] · (NO₃)₂ · 2Et₂O · 4H₂O (2) can be isolated from a DMF-EtOH mixture. A 4:1 mole ratio in DMF-EtOH gave the unusual polynuclear complex [Zn₄Nd₂L₄(1,4-BDC)₂] · [ZnNdL(NO₃)₃(OAc)]₂ (3). The NIR photophysical properties of the new compounds are reported.
