1.  6-(2-Chloro­benz­yl)-1-(4-chloro­phen­yl)-7-hy­droxy-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-5-one 
The title compound, C19H15Cl2N3O2, was obtained by a one-step cyclo­condensation of 2-amino-1-(4-chloro­phen­yl)imidazoline with diethyl (2-chloro­benz­yl)malonate under basic conditions. In the crystalline state, the mol­ecule exists as the 7-hy­droxy-5-oxo tautomer. The dihedral angles between the fused imidazopyrimidine and aromatic chloro­phenyl and chloro­benzyl rings are 14.2 (1) and 70.7 (1)°, respectively. The conformation of the mol­ecule is influenced by the intra­molecular C—H⋯O and C—H⋯N hydrogen bonds, giving a nearly planar five-ring fused system [maximum deviation from the mean plane = 0.296 (2) Å]. In the crystal structure, strong inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into chains along the c axis. These chains are further stabilized by weak C—H⋯Cl and π–π inter­actions [centroid–centroid distance = 3.6707 (12) Å].

25.  (2-Hy­droxy-7-meth­oxy­naphthalen-1-yl)(4-methyl­phen­yl)methanone 
In the title compound, C19H16O3, an intra­molecular O—H⋯O=C hydrogen bond is formed between the hy­droxy and carbonyl groups on the naphthalene ring system, resulting in an S(6) ring. The angles between the C=O bond vector and the least-squares planes of the naphthalene ring system and the benzene ring are 27.63 (6) and 47.99 (7)°, respectively. The dihedral angle between the latter planes is 61.39 (5)°. In the crystal, two mol­ecules are connected by pairs of inter­molecular O—H⋯O=C hydrogen bonds, forming centrosymmetric dimers with an R 2 2(4) graph-set motif. The mol­ecular packing features C—H⋯π interactions.
