2-(2-Hydroxyethyl)phthalazin-1(2H)-one
In the mol-ecule of the title compound, C(10)H(10)N(2)O(2), the rings are nearly coplanar, making a dihedral angle of 2.35 (5)°. In the crystal structure, inter-molecular C-H⋯O, C-H⋯N and O-H⋯O hydrogen bonds link the mol-ecules, generating R(4) (4)(22) and R(4) (4)(24) ring motifs to form a three-dimensional network. A weak π-π inter-action between the pyridazinone and benzene rings further st...
متن کاملPhthalazin-1(2H)-one–picric acid (1/1)
The geometric parameters of the title compound, C(8)H(6)N(2)O·C(6)H(3)N(3)O(7), are in the usual ranges. The three nitro groups are almost coplanar with the aromatic picrate ring [dihedral angles 10.2 (2)°, 7.62 (16) and 8.08 (17)°]. The mol-ecular conformation of the picric acid is stabilized by an intra-molecular O-H⋯O hydrogen bond. The phthalazin-1(2H)-one mol-ecules are connected via N-H⋯O...

In the title compound, C(14)H(7)FN(2)OS, prepared by the reaction of 2-bromo-4-fluoro-benzoyl choride with 2-mercaptobenzimidazole, the four-membered fused-ring system is essentially planar [maximum deviation from the mean plane = 0.035 (2) Å]. The crystal packing is stabilized by weak inter-molecular π-π [minimum ring centroid-centroid separation = 3.509 (7) Å], weak C-F⋯π [F⋯centroid = 3.4464...

In the title compound, C(15)H(10)N(2)OS, prepared by the reaction of 2-iodo-5-methyl-benzoyl chloride with 2-mercaptobenzimidazole, the four-membered fused-ring system is essentially planar [maximum deviation from the least-squares plane = 0.137 (6) Å]. The crystal packing is stabilized by weak inter-molecular π-π inter-actions [minimum ring centroid separation = 3.536 (4) Å] and weak C-H⋯π int...
متن کامل(1Z)-1-(2,4-Dichlorophenyl)ethan-1-one semicarbazone
In the title compound, C(9)H(9)Cl(2)N(3)O, the semicarbazone group is approximately planar, with an r.m.s deviation from the mean plane of 0.011 (2) Å. The dihedral angle between the least-squares planes through the semicarbazone group and the benzene ring is 38.76 (9)°. The crystal structure is further stabilized by N-H⋯O and C-H⋯O hydrogen bonding.
