(±)-trans-5-Benzoyl-4-(3-bromophenyl)-2-(1H-indol-3-yl)-4,5-dihydrofuran-3-carbonitrile
The furan ring in the title compound, C(26)H(17)BrN(2)O(2), adopts a twisted envelope conformation. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O inter-action which generates an S(6) ring motif. The crystal packing is stabilized by N-H⋯O and C-H⋯Br inter-actions, generating an R(2) (2)(16) ring motif and a C(12) linear chain motif, respectively. Weak C-H⋯π bonding is also o...
متن کامل(±)-trans-5-Benzoyl-2-(1H-indol-3-yl)-4-phenyl-4,5-dihydrofuran-3-carbonitrile
The furan ring in the title compound, C(26)H(18)N(2)O(2), is twisted about the C(H)-C(H) bond. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O inter-action, which generates an S(6) ring motif. The presence of N-H⋯N hydrogen bonds leads to inversion dimers, which are stabilized in the crystal packing by C-H⋯O and C-H⋯π inter-actions, forming layers that stack along the a axis.
متن کامل1-Benzoyl-3-chloroazepan-2-one
In the crystal structure of the title compound, C(13)H(14)ClNO(2), inter-molecular C-H⋯O inter-actions link the mol-ecules into a two-dimensional network.
متن کامل5-Benzoyl-4-(4-fluorophenyl)-3,4-dihydropyrimidin-2(1H)-one
In the title mol-ecule, C(17)H(13)FN(2)O(2), the 3,4-dihydro-pyrimidine ring adopts a flattened sofa conformation with the flap atom (which bears the fluoro-phenyl substituent) deviating from the plane defined by the remaining five ring atoms by 0.281 (2) Å. This plane forms dihedral angles of 85.98 (6) and 60.63 (6)° with the 4-fluoro-phenyl and benzoyl-phenyl rings, respectively. The dihedral...
متن کاملCrystal structure of 4-(2-azidophenyl)-5-benzoyl-2-(1H-indol-3-yl)-1H-pyrrole-3-carbonitrile
In the title compound, C26H16N6O, the dihedral angles between the central pyrrole ring and the pendant indole ring system (r.m.s. deviation = 0.027 Å) and the azide-bearing benzene ring are 37.56 (8) and 51.62 (11)°, respectively. The azide group is almost coplanar with its attached benzene ring [C-C-N-N = 3.8 (3)°]. The benzoyl benzene ring is disordered over two orientations twisted with resp...
