N-[2-(N-Cyclohexylcarbamoyl)propan-2-yl]-N-(2-iodophenyl)prop-2-ynamide
In the title compound, C(19)H(23)IN(2)O(2), the cyclo-hexane ring adopts a chair conformation, and the mean plane of the propiolamide unit is approximately perpendicular to the benzene ring [dihedral angle = 88.12 (13)°]. Weak intra-molecular C-H⋯O hydrogen bonding is observed between the carbonyl group and the benzene ring. In the crystal, classical N-H⋯O hydrogen bonds and weak C-H⋯O inter-ac...
متن کامل(E)-2-Phenyl-N-tosylnon-2-en-4-ynamide
The mol-ecule of the title compound, C22H23NO3S, adopts an E conformation about the C=C bond. The dihedral angle between the benzene rings is 23.79 (5)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules, forming inversion dimers. The terminal butyl group is disordered over two sets of sites in a 0.559 (6):0.441 (6) ratio.
متن کاملN-(2-Hydroxyethyl)-N-(tricyclo[3.3.1.13,7]dec-2-yl)benzamide
The title adamantane derivative, C(19)H(25)NO(2), was synthesized as part of a study into potential anti-tuberculosis agents. The adamantane skeleton displays shorter than normal C-C bond lengths ranging between 1.5230 (15) and 1.5329 (16) Å. The structure displays O-H⋯O hydrogen bonding and an inter-digitated layered packing structure with distinct hydro-philic and hydro-phobic regions.
متن کاملN′-(3-Methylquinoxalin-2-yl)-N′-phenylbenzohydrazide
In the crystal structure of the title compound, C(22)H(18)N(4)O, the quinoxaline system makes dihedral angles of 86.59 (7) and 63.37 (9)° with the benzohydrazide and phenyl rings, respectively. The benzohydrazide ring makes a dihedral angle of 72.46 (10)° with the phenyl ring. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds, C-H⋯O contacts and C-H⋯π inter-actions.
متن کاملN,N′-Dimethyl-N,N′-bis(pyridin-2-yl)methanediamine
The title compound, C(13)H(16)N(4), consists of two pyridine rings which are linked by an N,N'-dimethyl-methane-amine chain. The pyridine rings adopt a twist conformation and the dihedral angle between them is 60.85 (5)°. The crystal packing is stabilized by weak C-H⋯π inter-actions.
