Self-assembly motifs of palladium(II) dicarboxypyridine complexes

Abstract

trans-Dichlorobis(3,5-dicarboxypyridine)palladium(II), 1, and the analogous 2,6-dimethyl-3,5-dicarboxypyridine complex, 2, self-assemble through similar hydrogen bonding motifs which involve interactions between (i) the carboxylic acid substituents and solvate molecules (methanol or water) and (ii) hydroxy groups and chloride ligands. In the case of 1 these motifs give rise to a compact 2D polymeric network, whereas 2 forms a solid with high thermal stability containing well-defined channels
