c-3,t-3-Dimethyl-r-2,c-7-diphenyl-1,4-diazepan-5-one
In the title compound, C(19)H(22)N(2)O, the diazepine ring adopts a distorted chair conformation. One of the N-H groups forms an inter-molecular N-H⋯O hydrogen bond generating an R(2) (2)(8) graph-set motif. The other N-H group does not form a hydrogen bond.
متن کاملt-3-Ethyl-r-2,c-7-bis(4-methoxyphenyl)-1,4-diazepan-5-one
The title compound, C(21)H(26)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. In both independent mol-ecules, the diazepine ring adopts a chair conformation. In the crystal, the independent mol-ecules exist as N-H⋯O hydrogen-bonded R(2) (2)(8) dimers which are linked via N-H⋯O hydrogen bonds, forming tetra-mers. The tetra-mers are linked by C-H⋯O hydrogen bonds. I...
متن کامل6-Methyl-2,7-diphenyl-1,4-diazepan-5-one
The title compound, C(18)H(20)N(2)O, crystallizes with two mol-ecules in the asymmetric unit. The seven-membered ring in both mol-ecules adopts a distorted chair conformation. The dihedral angles between the phenyl rings are 43.2 (1) and 54.7 (1)° in the two mol-ecules. The crystal packing features N-H⋯O and weak N-H⋯π and C-H⋯π inter-actions.

In the title compound, C(20)H(21)NO(2), the piperidine ring adopts a distorted boat conformation. The dihedral angle between the two phenyl rings is 61.33 (18)°. In the crystal, inter-molecular C-H⋯O inter-actions link the mol-ecules into zigzag C(5) chains running parallel to [100].
متن کامل1-Dichloroacetyl-t-3,t-5-dimethyl-r-2,c-6-diphenylpiperidin-4-one
In the title compound, C21H21Cl2NO2, the piperidine ring adopts a distorted boat conformation. The phenyl rings substituted at the 2- and 6-positions of the piperidine ring subtend angles of 87.9 (7) and 70.8 (9)°, respectively, with the best plane through the piperidine ring. In the crystal, mol-ecules are connected by C-H⋯O and C-H⋯Cl inter-actions into layers in the ab plane.
