Crystal structure of 6-hy­droxy-5-(2-meth­oxy­phenoxy)-2,2′-bipyrimidin-4(3H)-one

In the title compound, C15H12N4O4, the dihedral angle between the heterocyclic rings is 12.60 (8)°, and that between the benzene ring and the adjacent heterocyclic ring is 85.14 (6)°. In the crystal, a combination of N-H⋯O and O-H⋯O hydrogen bonds link mol-ecules related by a glide plane into a C(5) C(6)[R (2) 2(9)] chain of rings, which is a distinctly different packing motif to those observed...

Crystal structure of 6-chloro-5-(2-chloro­eth­yl)-3-(propan-2-yl­idene)indolin-2-one

The title compound, C13H13Cl2NO, has a 3-(propan-2-yl-idene)indolin-2-one core with a Cl atom and a chloro-ethyl substituent attached to the aromatic ring. Two atoms of the aromatic ring and the chloro-ethyl substituent atoms are disordered over two sets of sites with a refined occupancy ratio of 0.826 (3):0.174 (3). In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, formin...

4-Hy­droxy-5-(2-meth­oxy­phen­oxy)-2,2′-bipyrimidin-6(5H)-one dihydrate

The title compound, C15H12N4O4·2H2O, crystallizes with two independent water mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the benzene and pyrimidine rings and that of the pyrimidin-4-one ring are 85.1 (9) and 82.1 (1)°, respectively. The mean plane of the pyrimidine ring is twisted by 12.8 (8)° from that of the pyrimidin-4-one ring. The dihedral angles betwe...

Crystal structure of 5-(4-benzyl­oxyphen­yl)-3-(4-meth­oxy­phen­yl)-6-methyl­cyclo­hex-2-en-1-one

The title compound, C27H26O3, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule A, the plane of the central benzene ring forms dihedral angles of 75.78 (14) and 52.75 (16)° with that of the terminal benzene rings, and the dihedral angle between the planes of the terminal benzene rings is 51.49 (17)°. The corresponding values for mol-ecule B are 75.18 (1...

Crystal structure of 1-ethyl-5-iodo­indolin-2-one

In the title indolinone derivative, C10H10INO, all the non-H atoms, except the terminal methyl C atom, are almost coplanar. The mol-ecules are arranged into columns extending along the a-axis direction and inter-act with the mol-ecules in adjacent columns via C-H⋯O hydrogen bonds [H⋯O distance = 2.57 (3) Å] and I⋯I short contacts of 3.8986 (3) Å. A one-dimensional zigzag iodine chain along the ...
