The rings of the three-ring cytisine system in the title compound [systematic name: (1R,5S)-1,2,3,4,5,6-hexa-hydro-1,5-methano-8H-pyrido[1,2-a][1,5]diazo-cine-8-thione], C(12)H(16)N(2)S, have planar [maximum deviation 0.0170 (7) Å], half-chair and chair conformations. In the crystal structure, relatively short and directional C-H⋯π inter-actions and weaker secondary C-H⋯S contacts join the mol-...

In the title compound, CH3OC(O)NHP(O)(OCH3)2, the P atom has a slightly distorted tetra-hedral configuration. The mixed imide moiety can be described as cisoid-transoid in which the two opposing dipoles (P=O and C=O) are oriented with a O=C⋯P=O torsion angle of 150.88(18)°. In the crystal, molecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers.

In the structure of the title compound (NP2MBA), C(14)H(13)NO, the conformation of the C-O bond is syn to the ortho-methyl substituent in the benzoyl phenyl ring, while the N-H bond is anti to the ortho-methyl substituent. The structure of NP2MBA closely resembles that of 2-chloro-N-phenyl-benzamide, with similar bond parameters. The dihedral angle between the phenyl and benzoyl rings is 88.05 ...

Background:Ecstasy, mainly composed of 3,4-methylenedioxymethamphetamine (MDMA), is one of the most popular addictive synthetic drugs. This study was aimed to investigate the amount of MDMA in the ecstasy tablets seized in West Azerbaijan province, northwest Iran and also to assess the relationship between the physicochemical and morphological characteristics of the tablets. Methods: MDMA conte...
