ABSTRACT: In the title compound, C18H17ClN2O4, the dihedral angle between the benzofuran ring system [maximum deviation 0.014?(2)?Å] and the oxopyradizine ring is 73.33?(8)°. The structure is characterized by disorder of the ethyl group, which is split into two parts, with a major component of 0.57?(3), and the acetate carbonyl O atom, which is statistically disordered. In the crystal, the molecules are linked by C-H?O inter-actions, forming a three-dimensional network.

In the title compound, C18H17ClN2O4, the dihedral angle between the benzofuran ring system [maximum deviation 0.014 (2) Å] and the oxopyradizine ring is 73.33 (8)°. The structure is characterized by disorder of the ethyl group, which is split into two parts, with a major component of 0.57 (3), and the acetate carbonyl O atom, which is statistically disordered. In the crystal, the molecules are linked by C-H⋯O inter-actions, forming a three-dimensional network. ...[more]

Crystal structure and Hirshfeld surface analysis of ethyl 2-[5-(3-chloro-benz-yl)-6-oxo-3-phenyl-1,6-di-hydro-pyridazin-1-yl]acetate.

Project description:The title pyridazinone derivative, C21H19ClN2O3, is not planar. The unsubstituted phenyl ring and the pyridazine ring are inclined to each other, making a dihedral angle of 17.41?(13)° whereas the Cl-substituted phenyl ring is nearly orthogonal to the pyridazine ring [88.19?(13)°]. In the crystal, C-H?O hydrogen bonds generate dimers with R 2 2(10) and R 2 2(24) ring motifs which are linked by C-H?O inter-actions, forming chains extending parallel to the c-axis direction. The inter-molecular inter-actions were investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots, revealing that the most significant contributions to the crystal packing are from H?H (44.5%), C?H/H?C (18.5%), H?O/H?O (15.6%), Cl?H/H?Cl (10.6%) and C?C (2.8%) contacts.

2-Chloro-N-(2-chloro-benzo-yl)-N-(2-ethyl-4-oxo-3,4-di-hydro-quinazolin-3-yl)benzamide.

Project description:In the title compound, C24H17Cl2N3O3, the quinazolinone ring system is close to planar (r.m.s. deviation = 0.0132?Å), with the imide unit almost perpendicular to it, subtending a dihedral angle of 89.1?(1)°. However, the imide unit itself is not planar, the dihedral angle between the two O=C-N components being 34.6?(1)°. The dihedral angle between the two chlorobenzene rings is 40.50?(7)°, while the angles between these rings and the imide moiety are 54.6?(1) and 58.2?(1)°, respectively. The dihedral angles between the 2-chloro-phenyl rings and the quinazolinone ring system are 48.77?(5) and 32.92?(7)° for rings A and B, respectively. In the crystal, weak C-H?O inter-actions link the mol-ecules into a three-dimensional array.

Ethyl 2-(3-ethyl-sulfinyl-5-methyl-1-benzo-furan-2-yl)acetate.

Project description:The title compound, C(15)H(18)O(4)S, was prepared by the oxidation of ethyl 2-(3-ethyl-sulfanyl-5-methyl-1-benzofuran-2-yl)acetate with 3-chloro-peroxy-benzoic acid. The crystal structure is stabilized by aromatic π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.655 (3) Å] and by three inter-molecular C-H⋯O non-classical hydrogen bonds.

Ethyl 2-[6-(4-methyl-benzo-yl)-7-phenyl-2,3-di-hydro-1H-pyrrolizin-5-yl]-2-oxo-acetate.

Project description:In the title compound, C25H23NO4, the pyrrolizine ring is approximately planar with an r.m.s deviation from planarity of 0.0053?Å, while the fused di-hydro-pyrrolizine ring adopts an envelope conformation with the C atom connected to two CH2 as the flap. The dihedral angles between the fused ring system and the phenyl and methyl-benzoyl rings are 41.65?(11) and 66.30?(8)°, respectively. In the crystal, weak C-H?O hydrogen bonds and C-H?? inter-actions occur. One mol-ecule is linked to five adjacent ones through eight hydrogen bonds, forming a three-dimensional network.

Crystal structure of ethyl (6-hy-droxy-1-benzo-furan-3-yl)acetate sesquihydrate.

Project description:In the title hydrate, C12H12O4·1.5H2O, one of the water mol-ecules in the asymmetric unit is located on a twofold rotation axis. The mol-ecule of the benzo-furan derivative is essentially planar (r.m.s. deviation for the non-H atoms = 0.021?Å), with the ester group adopting a fully extended conformation. In the crystal, O-H?O hydrogen bonds between the water mol-ecules and the hy-droxy groups generate a centrosymmetric R 6 (6)(12) ring motif. These R 6 (6)(12) rings are fused, forming a one-dimensional motif extending along the c-axis direction.

1-[4-(4-Chloro-phen-yl)piperazin-1-yl]-3-(6-oxo-3,4-diphenyl-1,6-dihydro-pyridazin-1-yl)propan-1-one.

Project description:In the title compound, C(29)H(27)ClN(4)O(2), the six-membered ring of the pyridazine group is nearly planar [maximum deviation = -0.062?(2)?Å] and its mean plane makes dihedral angles of 43.05?(9), 44.71?(10) and 72.57?(9)°, respectively, with the two phenyl and benzene rings. The piperazine ring has a chair conformation and its mean plane is almost perpendicular to the attached benzene ring, with a dihedral angle of 83.20?(16)°. In the crystal, mol-ecules are linked via two pairs of C-H?O inter-actions, which result in the formation of chains propagating along [10-1]. Neighbouring chains are linked via C-H?? inter-actions.
