Abstract

A series of four new manganese(II) complexes based on the L4-X ligand, where L is N-(4-halo)phenyl picolinamide ligands, have been synthesized, characterized and their supramolecular crystal structures were studied by geometrical analysis and theoretical calculation. Our study reveals the role of weak intermolecular interactions involving halogens, such as C-H center dot center dot center dot X hydrogen bonds (in the cases of 1 and 2) and C-X center dot center dot center dot X'-M halogen bonds (in the cases of 3 and 4), in the structural changes of supramolecular assemblies of coordination compounds. This study could provide further insight into discovering the role of weak intermolecular interactions in the context of metallosupramolecular assembly.
