Crystal structure of 2-[9-(2-hydroxyphenyl)-1,8-dioxo-1,2,3,4,5,6,7,8,9,10decahydroacridin-10-yl]acetic acid
The title compound, C21H21NO5, crystallizes with two molecules in the asymmetric unit. In each molecule, the central 1,4-dihydropyridine ring adopts a shallow sofa conformations (with the C atom bearing the phenol ring as the flap), whereas the pendant cyclohexene rings both have twisted-boat conformations. Each molecule features an intramolecular O—HO hydrogen bond, which closes an S(8) ring. In the crystal, ... Read more

Crystal structure of (E)-1-{[(3,5-di­methyl­phen­yl)imino]­meth­yl}naphthalen-2-ol
The title compound, C19H17NO, has an _E_ conformation about the N=C bond. The mol­ecule is relatively planar, with the benzene ring and naphthalene ring plane being inclined to one another by 4.28 (10)°. There is an intra­molecular O-HN hydrogen bond generating an _S_(6) ring motif. In the crystal, mol­ecules are linked _via_ C-HO hydrogen bonds, forming chains propagating along [100]. ... Read more
