9-(3-Bromo-5-chloro-2-hy­droxy­phen­yl)-10-(2-hy­droxy­eth­yl)-1,2,3,4,5,6,7,8,9,10-deca­hydro­acridine-1,8-dione

In the title compound, C₂₁H₂₁BrClNO₄, the dihydro­pyridine ring adopts a flattened boat conformation. The 3-bromo-5-chloro-2-hy­droxy­phenyl ring forms a dihedral angles of 84.44 (7)° with the dihydro­pyridine mean plane. The mol­ecular conformation is stabilized by an intra­molecular O—H...O hydrogen bond, with an S(8) ring motif. In the crystal, O—H...O and C—H...O hydrogen bonds link the mol­ecules, forming a three-dimensional network.

1-{(Z)-[(2,3-Dihy­droxy­prop­yl)amino]­methyl­idene}naphthalen-2(1H)-one

In the title mol­ecule, C₁₄H₁₅NO₃, the ring system is essentially planar, with an r.m.s. deviation of 0.003 Å. The atoms of the ethane-1,2-diol group were refined as disordered over two sets of sites in a ratio of 0.815 (3):0.185 (3). The mol­ecular conformation is stabilized in part by an intra­molecular N—H...O hydrogen bond, which forms an S(6) ring. In the crystal, mol­ecules are connected by N—H...O and O—H...O hydrogen bonds, forming a two-dimensional network parallel to (100). The network also features weak C—H...O hydrogen bonds. Weak C—H...π inter­actions also observed.
