1-[(E)-4-(5-Bromo-1H-indol-3-yl)-1-methyl-2,5,6,7-tetrahydro-1H-azepin-2-ylidene]propan-2-one
In the title compound, C(18)H(19)BrN(2)O, the seven-membered azepine ring adopts a twist-boat conformation: the bond angles about the azepine N atom are indicative of sp(2) hybridization. The dihedral angle between the plane of the carbon-carbon double bond of the enone unit and the mean plane of the indole ring is 27.8 (1)°. In the crystal, an N-H⋯O hydrogen bond links the mol-ecules into chai...
متن کاملNaphthalene-2,6-dicarboxylic acid–1-methylpyrrolidin-2-one (1/2)
The asymmetric unit of the title compound, C(12)H(8)O(4)·2C(5)H(9)NO, contains one half-mol-ecule of naphthalene-2,6-dicarb-oxy-lic acid (NDA) and one mol-ecule of 1-methyl-pyrrolidin-2-one (NMP): the NDA molecules lie on the crystallographic twofold rotation axes. In the crystal, the components are linked by strong O-H⋯O hydrogen bonds and C-H⋯O inter-actions.

In the title compound, C(9)H(17)N(2) (+)·C(17)H(15)N(2)O(2)S(2) (-), the Csp(2)-N bonds in the tetra-hydro-pyrimidine ring of the cation are delocalized. The negative charge is localized on the S atom of the thione group. Cations and anions are linked by N-H⋯S inter-molecular hydrogen bonds.

In the title compound, C(11)H(12)ClN(5)O, the triazolone and pyrimidine rings are almost coplanar [dihedral angle = 2.98 (14)°]. The total puckering amplitude Q(T) of the seven-membered lactam ring is 0.706 (3) Å.
متن کامل9-(2-Chlorobenzyloxy)-6,7-dihydro-2H-benzo[c][1,2,4]triazolo[4,3-a]azepin-3(5H)-one
In the title mol-ecule, C(18)H(16)ClN(3)O(2), the seven-membered ring adopts an envelope conformation with the flap atom deviating by 0.801 (5) Å from the mean plane formed by the remaining non-H atoms. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The crystal packing also exhibits weak inter-molecular C-H⋯N hydrogen bonds and π-π inter-actions with a sho...
