IntroductionOver the past few years considerable efforts have been devoted to the synthesis and structural characterization of coordination polymers. Studies involving zinc(ii) resulted in reports on chain polymers,1–5two­dimensional layer structures6,7and three­dimensional frameworks.8A general search of the Cambridge Structural Database (CSD)9for zinc complexes of any nuclearity confirms that coordination numbers of 4, 5 and 6 are commonly encountered.10Here, we report eight new crystal structures involving the coordination of pyridine derivatives to zinc(ii) halides (Scheme 1).Our selection is intended to demonstrate the interplay between coordination geometry, steric requirements of the ligands, and intermolecular interactions. Issues of packing and space filling will be addressed.
