In bis(4-methylpiperidine-κN)gold(I) chloride, [Au(C6H13N)2]Cl (1), the methyl groups are, as expected, equatorial at the piperidine ring, but the Au atom is axial; this is the case for all five structures reported here, as is the expected linear co

In the structure of the title compound, C15H19N3O5S2, the bond lengths at the linking sulfur atom are significantly different [1.7473 (17) and 1.811 (2) Å], and the angle at the exocyclic nitrogen atom is wide at 128.45 (18)°. The interplanar angle

The title compounds 3a, C14H13N5OS, and 3b, C13H12N6OS, both show an E configuration about the N=C bond and a planar NH2 group. The molecules, which only differ in the presence of a phenyl (in 3a) or pyridyl (in 3b) substituent, are closely similar e

In the title compound, C13H15N3O5S, the two rings face each other in a `V′ form at the S atom, with one N—H...O=S and one C—H...O=S contact from the pyrazolyl substituents to the sulfonyl group. Two classical hydrogen bonds from the amine group
