Synthesis, structure and near-infrared (NIR) luminescence of three solvent-induced pseudo-polymorphic complexes from a bimetallic Zn-Nd Schiff-base molecular unit

Three solvent-induced pseudo-polymorphic bimetallic Zn-Nd complexes [ZnNdL(OAc)(NO3)(2)(DMF)] solvate (solvate: MeCN (1), THF (2), EtOH (3): H2L = N,N'-bis(3-methoxy-salicylidene)phenylene-1,2-diamine) were obtained, and their solid NIR luminescence related to the packing structure from the intermolecular pi-pi interactions was discussed.
