Hbipy+ cations and anionic acid in compound I are linked to form a chain by means of C-H..-O hydrogen bonds. Adjacent chains are further extended into a two-dimensional layer network via N-H.O and O-H-N hydrogen bonds. In compound 2, the acid and base subunits are arranged alternately to generate a linear tape motif via N-H...O hydrogen bonds; these tapes are further combihed into a three-dimensional array with CdSO4 topology via C-H...O intermolecular hydrogen bonds.展开更多
