Crystal structure, spectroscopic characterization and Hirshfeld surface analysis of trans-di­aqua­[2,5-bis­(pyridin-4-yl)-1,3,4-oxa­diazole]di­thio­c…

2019

The NiII atom in the mononuclear title complex has an almost regular octa­hedral N4O2 coordination geometry. In the crystal, the complex mol­ecules are linked in a three-dimensional network through strong O—H⋯N hydrogen bonds.

The title compound, C16H24Cl2O, crystallizes with two independent molecules in the asymmetric unit. Each molecule is built up from two fused six-membered rings, one of which is fused to a three-membered ring. The two molecules differ essentially in the orientation of two of the methyl groups. The dihedral angles between the mean planes through the two six-membered rings are 57.98 (13) and 55.29 (13)°. The molecular conformation is stabilized by intramolecular C—H...Cl hydrogen bonds.

The structure of the title compound is isotypic with that of the analogous nickel(II) complex, in which the CoN6 core shows an axially weakly compressed octa­hedral geometry as opposed to the almost regular geometry exhibited by the NiN6 octa­hedron.

5-Acetyl-6-methyl-4-phenyl-1-(prop-2-ynyl)-3,4-dihydropyrimidin-2(1H)-one

2017

The 4-dihydropyrimidin-2(1H)-one moiety of the title molecule, C16H16N2O2, displays a half-chair conformation. The least-squares mean plane through this heterocycle is almost perpendicular to the aromatic ring [dihedral angle = 89.52 (8)°] and to the prop-2-ynyl chain [C—C—N—C torsion angle of −73.2 (2)°]. The mean plane through the acetyl group makes a dihedral angle of 30.93 (10)° with the mean plane of the heterocycle. There is an intramolecular C—H...O hydrogen bond forming anS(6) ring motif. In the crystal, molecules are linked by pairs of N—H...O hydrogen bonds forming inversion dimers.
