Crystal structure of 13-phenyl-2,3,4,13-tetrahydro-1H-indazolo[1,2-b]phthalazine-1,6,11-trione
The title compound, C21H16N2O3, consists of an indazolone moiety, bearing a phenyl group, fused to a phthalazine ring system (r.m.s. deviation = 0.018 Å). The phenyl ring is almost normal to the mean plane of the five-membered ring of the indazolone moiety, making a dihedral angle of 89.64 (7)°. The six-membered ring of the indazolone moiety has an envelope conformation, with the central methyl...

The asymmetric unit of the title compound, C20H20N2O3·H2O, contains two independent mol-ecules (A and B), with similar conformations and two independent water mol-ecules. In the crystal, N-H⋯O and Owater-H⋯O hydrogen bonds link all moieties into two crystallographically independent kinds of sheets parallel to the ac plane. These independent sheets, each containing either A or B mol-ecules, are ...
متن کاملSynthesis, Crystal Structure and DFT Studies of 1,3-Dimethyl-5-propionylpyrimidine- 2,4,6(1H,3H,5H)-trione
Novel 1,3-Dimethyl-5-propionylpyrimidine-2,4,6(1H,3H,5H)-trione was synthesized and recrystallized from ethanol. The compound was characterized by 1H NMR, 13C NMR in CDCl3, DMSO-d6 and acetone-d6, elemental analysis and X-ray diffraction. The NMR data observed that the title compound exists in the enol tautomer rather than keto, and it stabilized by strong H-bond as observed form the NMR data a...
متن کاملCrystal structure of 13-(2-methoxyphenyl)-3,4-dihydro-2H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione
In the title compound, C22H18N2O4, the three fused rings of the pyrazolo-phthalazine moiety are coplanar (r.m.s. deviation = 0.027 Å). The cyclo-hexene ring fused to the pyrazolidine ring, so forming the indazolophthalazine unit, has a half-chair conformation. The benzene ring is almost normal to the mean plane of the pyrazolo-phthalazine moiety, with a dihedral angle of 87.21 (6)° between thei...
متن کاملCrystal structure of 3-methyl-1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazole-4-carbaldehyde
In the title compound, C15H13N3O, the pyrrolyl and phenyl rings make dihedral angles of 58.99 (5) and 34.95 (5)°, respectively, with the central pyrazole ring. In the crystal, weak, pairwise C-H⋯O inter-actions across centers of symmetry form dimers, which are further associated into corrugated sheets running approximately parallel to (100) via weak C-H⋯N inter-actions.
