Abstract

Reactions of heterobimetallic 3d-4f Schiff base complexes of the formula [ZnLnL(H2O)(NO3)3] (1a-e) with KOCN or NH4SCN in refluxing MeCN produce either one dimensional polymeric materials [ZnLnL(NO3)2(H2O)(OCN)]∞(2a-c) or trinuclear complexes of the formula [Zn2LnL2(NO3)(SCN)2] (3a-e) (a (La), b (Nd), c (Er), d (Tb), e (Eu); H2L = N,N′-bis-(3- methoxysalicylidene)ethylene-1,2-diamine). The structures of 2a,b and 3b-e have been determined by single-crystal X-ray diffraction studies. Structural differences between the complexes affect the photophysical properties, which have been studied in acetonitrile solutions.
