With the Zn-Schiff-base [ZnL(CH3CN)] from the pure Salen-type Schiff-base ligand H2L (H2L = N,N'-bis (salicylidene)phenylene-1,2-diamine) as the precursor, a hetero-trinuclear Zn2Nd complex [Zn2Nd(L)(2)(NO3)(3)(CH3CN)(2)] (1) and a hetero-binuclear ZnNd complex [ZnNd(L)(2)Cl(DMF)] (2) are obtained by the further reaction with Nd(NO3)(3)center dot 6H(2)O or NdCl3 center dot 6H(2)O, respectively. The influence of structural differences of the two complexes on their photophysical properties shows the anionic inducement leads to the effective modulation of the NIR luminescent properties by the adjustment of the coordination sphere of the Nd3+ ions.
