Assembling one-dimensional coordination polymers into threedimensional architectures via hydrogen bonds

Abstract

The reactions of bis(pyridylcarboxamido)alkanes(amides) and bis(3-pyridyl)alkanediamides (reverse amides) with copper(II) and zinc(II) in the presence of various anions resulted in onedimensional polymeric crystalline complexes with or without guest inclusion. The crystal structure analyses of these complexes reveal that the one-dimensional networks observed here are of three types: simple linear chain, chains with wavy nature and chains containing cavities. The self-complementary amide groups of the ligands assembled these coordination networks into higher dimensional architectures via N-H···O hydrogen bonds. © Indian Academy of Sciences.
