The crystal structures of bis-guanidinium tetrachlorozincate(II) and bis-guanidinium tetrabromozincate(II) have been determined by X-rays. Both crystal structures are highly isomorphous; the descriptors of the isomorphism phenomenon are discussed and applied to the present case. The zinc ions are tetrahedrally coordinated. An extensive network of hydrogen bonds determine crystal packing. In each structure, two symmetrically independent cations exhibit quite different hydrogen bond patterns. These patterns are described and discussed in terms of graph set analysis.
