In the title compound, C19H18ClNOS, the thiazin-3-one ring adopts a slightly distorted screw-boat conformation. An intramolecular C—H...S hydrogen bond encloses anS(6) ring and affects the overall conformation of the molecule. The dihedral angle between the two phenyl rings is 52.3 (2)°. In the crystal, weak C—H...O intermolecular interactions stabilize the crystal packing.

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.

In the title compound, C20H18NO3P, the C=O and P=O groups of the carbacylamidophosphate (CAPh) fragments are located in a synclinal position relative to each other and are pre-organized for bidentate chelate coordination of metal ions. The N—H group is involved in the formation of an intramolecular hydrogen bond. In the crystal, molecules do not form strong intermolecular interactions but the molecules are linked via weak C—H...π interactions, forming chains along [001].

Title Molecule

The title molecule, C13H16N6, crystallizes from hexane as a molecular crystal with no strong intermolecular interactions (the shortest C—H...N contact is longer than 3.38 Å). A relatively short intramolecular contact (3.09 Å) has a C—H...N angle of 118° which is quite small to be still considered a hydrogen bond. The three pyrazole rings form a propeller-like motif, with one methylpyrazole unit almost perpendicular to the mean plane of the three rings [82.20 (6)°]. The other two methylpyrazole units, with nitrogen donor atoms oriented in opposite directions, are oriented at 67.26 (6) and 72.53 (6)° to the mean plane.
