In the title compound, C14H15N3O4S, the tetra­hydro­pyrimidine ring adopts a half-boat form. There are inter­molecular N—H⋯O hydrogen bonds and π–π stacking inter­actions. [ABSTRACT FROM AUTHOR]

The title compound, C12H22ClNO, adopts the square conform­ation [3333] observed in other known saturated twelve-membered rings. Disorder is observed, resulting from exchange of the chloro and nitroso substituents. [ABSTRACT FROM AUTHOR]

The crystal structure of the title compound, C17H20N2O5, is stabilized by C—H...O and N—H...O hydrogen bonds. [ABSTRACT FROM AUTHOR]

In the title compound, C22H16N2S2, the benzothiazole and tolyl ring systems are inclined at an angle of 31.23 (8)°, and the dihedral angle between the phenyl and benzothiazole rings is 7.567 (2)°. In the crystal structure, intermolecular C—H...N hydrogen bonds link the molecules into a two-dimensional sheet and π–π stacking interactions [perpendicular distance 3.6170 (4) Å] reinforce the crystal cohesion.

In the title compound, C14H13N3O2S, the imidazothia­diazole ring system and the methoxy­phenyl ring are not coplanar, having an angle of 31.60 (7)° between their mean planes. In the crystal structure, inter­molecular C—H⋯O hydrogen-bond inter­actions link the mol­ecules into dimers and π–π stacking inter­actions reinforce the crystal cohesion. [ABSTRACT FROM AUTHOR]

In the title compound, C14H10O4S2·0.5CH3OH, the molecule adopts a gauche conformation around the central C—C bond. Intermolecular O—H...O hydrogen bonds between carboxyl groups link the molecules into zigzag chains. Between chains, the thiophene rings form π–π stacking interactions with a centroid–centroid distance of 3.98 Å. The methanol solvent molecule forms an O—H...O hydrogen bond to one carboxyl group and is disordered about a crystallographic centre of inversion. [ABSTRACT FROM AUTHOR]
