12-(3,4,5-Trimethoxyphenyl)-2,3,4,12-tetrahydro-1H-5-oxatetraphen-1-one: crystal structure and Hirshfeld surface analysis
In the title compound, C26H24O5, the pyran ring has a flattened-boat con-formation, with the 1,4-related ether O and methine C atoms lying 0.1205 (18) and 0.271 (2) Å, respectively, above the least-squares plane involving the doubly bonded C atoms (r.m.s deviation = 0.0208 Å). An envelope conformation is found for the cyclo-hexene ring, with the flap atom being the middle methyl-ene C atom, lyi...

The asymmetric unit of the title compound, C(18)H(22)N(2), contains two independent mol-ecules which differ slightly with respect to the torsion angles involving the atoms joining the adamantyl and benzimidazole groups. The bond angles in the adamantane cage vary within the range 108.27 (9)-110.55 (10)°. The benzimidazole ring system in both mol-ecules is essentially planar, the maximum deviati...

The title compound, C(10)H(12)N(2)O(2), was synthesized by cyclization of 3-(1-ethyl-pyrrole-2-carboxamido)propanoic acid in the presence of polyphospho-ric acid and diphospho-rus pentoxide. In the crystal structure, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds, forming chains extending along the b axis.

5-[(1-Benzyl-1H-1,2,3-triazol-4-yl)methyl]-5H-dibenzo[b,f]azepine
In the title compound, C24H20N4, the azepine ring adopts a boat conformation and the dihedral angle between the benzene rings fused to it is 57.95 (8)°. The bond-angle sum at the azepine N atom is 346.6°, indicating a significant deviation from planarity. The triazole ring subtends a dihedral angle of 71.45 (10)° with the terminal phenyl group. A weak intra-molecular C-H⋯Na (a = azepine) inter-...
