4-Methoxy-4-methyl-6-phenyl-1,3-diazinane-2-thione
In the title pyrimidine derivative, C12H16N2OS, the tetra-hydro-pyrimidine ring adopts an envelope conformation with the C atom of the methyl-ene -CH2- group as the flap. In the crystal, N-H⋯O and N-H⋯S hydrogen bonds connect mol-ecules into undulating sheets perpendicular to the a axis.

In the title compound, C(17)H(18)N(2)O(2)S, the 1,3-diazinane-2-thione ring system is not coplanar with the benzene ring and meth-oxy-phenyl ring system, the dihedral angle between the planes being 65.58 (13) and 89.18 (10)°, respectively. The crystal structure is characterized by inter-molecular O-H⋯S, N-H⋯S, N-H⋯O and C-H⋯S hydrogen bonding.

interesting results because of the regular arrangement of the molecules in the environment.1–3 We previously reported on the photocycloaddition reaction of 4-methoxy-6-methyl-2-pyrone (1a) (Fig. 1) with maleimide (2) in the solid state to give a highly stereoselective [2 + 2] cycloadduct4 owing to the formation of two sets of 1:1 complex crystals between (1a) and (2) (Fig. 1).5 The crystal show...
متن کامل(5S,6R)-5-Methyl-6-phenyl-4-propyl-1,3,4-oxadiazinane-2-thione
The title mol-ecule, C(13)H(18)N(2)OS, is an oxadiazinanthione derived from (1R,2S)-norephedrine. There are two molecules in the asymmetric. Both adopt roughly half-chair conformations; however, the 5-position carbon orients out of opposite faces of the oxadiazinanthiones plane in the two molecules. In the crystal structure, they are oriented as a dimer linked by a pair of N-H⋯S hydrogen bonds....
متن کامل4-Phenyl-1H-imidazole-2(3H)-thione
In the asymmetric unit of the title compound, C(9)H(8)N(2)S, there are four symmetry-independent mol-ecules (Z' = 4). The geometrical features of these mol-ecules are quite similar: in the normal probability plots the R(2) correlation factors for bond lengths and angles are generally around 0.95. The twist angles between the imidazole and phenyl rings (which are planar within 3σ) range from 9.0...
