The complex poly[[aqua(μ2-phthalato-κ2O1:O2){μ3-2-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]acetato-κ4N2,N3:O:O′}{μ2-2-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]acetato-κ3N2,N3:O}dizinc(II)] dihydrate], {[Zn2(C10H8N3O2)2(C8H4O4)(H2O)]·2H2O}n, has been prepared by solvothermal reaction of 2-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]acetonitrile (PPAN) with zinc(II). Under hydrothermal conditions, PPAN is hydrolyzed to 2-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]acetate (PPAA−). The structure determination reveals that the complex is a one-dimensional double chain containing cationic [Zn4(PPAA)4]4+structural units, which are further extended by bridging phthalate ligands. The one-dimensional chains are extended into a three-dimensional supramolecular architectureviahydrogen-bonding and π–π stacking interactions.

The title compound, C15H16N2O2S, contains a five-membered thiophene ring fused to a benzene ring and a substituted pyrimidinone ring. All three rings in each of the independent molecules of the asymmetric unit lie in approximately the same plane. The crystal structure is stabilized by intermolecular C—H...O hydrogen bonding and π–π stacking interactions.

The molecular and supramolecular structures of eight N 4-substituted 2,4-diamino-6-benzyloxy-5-nitrosopyrimidines are discussed, along with one analogue containing no nitroso substituent. The nitroso derivatives all exhibit polarized molecular-electronic structures leading to extensive charge-assisted hydrogen bonding between the molecules. The intermolecular interactions include hard hydrogen bonds of N—H...O and N—H...N types, together with O—H...O and O—H...N types in the monohydrate of 2-amino-6-benzyloxy-4-piperidino-5-nitrosopyrimidine, soft hydrogen bonds of C—H...O, C—H...π(arene) and N—H...π(arene) types and aromatic π...π stacking interactions. The predominant supramolecular structure types take the form of chains and sheets, but no two of the structures determined here exhibit the same combination of hydrogen-bond types.
