Crystal structure of 3-{1-[(1-allyl-1H-indazol-6-yl)amino]-ethyl-idene}-6-methyl-2H-pyran-2,4(3H)-dione.

ABSTRACT: In the title compound, C18H17N3O3, the dihedral angle between the planes of the indazole ring system [maximum deviation = 0.012?(1)?Å] and the pyran-2,4-dione ring is 54.03?(6)°. An intra-molecular N-H?O hydrogen bond closes an S(6) ring. The same H atom also participates in an inter-molecular N-H?O hydrogen bond, which generates an inversion dimer. The dimers are linked by weak C-H?O contacts, thereby forming a three-dimensional network.

In the title compound, C18H17N3O3, the dihedral angle between the planes of the indazole ring system [maximum deviation = 0.012 (1) Å] and the pyran-2,4-dione ring is 54.03 (6)°. An intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. The same H atom also participates in an inter-molecular N-H⋯O hydrogen bond, which generates an inversion dimer. The dimers are linked by weak C-H⋯O contacts, thereby forming a three-dimensional network. ...[more]

Quinazoline-2,4(1H,3H)-dione.

Project description:In the title compound, C(8)H(6)N(2)O(2), inter-molecular N-H?O hydrogen bonds involving the amine and carbonyl groups create centrosymmetric dimers between adjacent nearly coplanar mol-ecules. These dimers are further connected by weak N-H?O hydrogen bonds, forming a two-dimensional network. Mol-ecules are packed in the crystal structure with adjacent benzene and pyrimidine rings approximately coplanar; the centroid-centroid separation is 3.863?Å and the dihedral angle between the mean planes is 0.64°, indicating the presence of weak inter-molecular face-to-face ?-? stacking inter-actions.

3-[1-(2-Hy-droxy-anilino)ethyl-idene]-3H-chromen-2,4-dione.

Project description:The title compound is a new amino-coumarin derivative, C17H13NO4, and was synthesized by the condensation of 2-amino-phenol and 3-acetyl-4-hy-droxy-coumarin. An intra-molecular N-H?O hydrogen bond generates an S(6) ring motif. In the crystal, the molecules are linked into chains extending in the [010] direction by O-H?O hydrogen bonds. There is also a ?-? stacking inter-action between the bicyclic coumarin fragment and the phenol ring [centroid-centroid distance = 3.7510?(14)?Å], and these ring systems form between them a dihedral angle of 53.3?(2)°. Intermolecular hydrogen bond C-H?O hydrogen bonding is also observed in the interconnection of the crystal packing.

Project description:In the title compound, C(10)H(10)N(2)O(2), all non-H atoms are approximately co-planar with an r.m.s. deviation of 0.016?Å. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H?O hydrogen bonds. Chains along [010] are buiilt up by ?-? inter-actions [centroid-centroid distance = 3.602?(1)?Å] between the benzene and piperazine rings of adjacent mol-ecules.

Project description:In the title hydrate, C(12)H(13)NO(4)·H(2)O, the piperidine ring that is fused to the benzene ring is in a sofa conformation with the chiral C atom lying 0.4084?(18)?Å out of the plane of the nine fused-ring atoms. In the crystal, O-H?O and N-H?O hydrogen bonds link the organic mol-ecules and water mol-ecules into chains running along the b-axis direction. The chains are further connected into layers parallel to the bc plane by ?-? inter-actions between inversion-related benzene rings [centroid-centroid distance = 3.8846?(9)?Å].

5-Ethyl-4a-meth-oxy-1,3-dimethyl-4a,5-dihydro-benzo[g]pteridine-2,4(1H,3H)dione.

Project description:The title compound, C(15)H(18)N(4)O(3), was formed by the reaction of methanol with 5-ethyl-1,3-dimethyl-alloxazinium perchlorate. Its structure mimics those of possible flavin inter-mediates in flavoenzymes. The heterocyclic rings are substituted with methyl, ethyl and meth-oxy groups. The central tricyclic skeleton is bent due to the presence of an sp(3) C atom. There are weak inter-molecular C-H?O inter-actions in the structure, forming a three-dimensional network.

Project description:The title compound, C(19)H(21)ClN(6)O(4), is a 1:2 adduct of p-chloro-benzaldehyde and uracil. It crystallizes with two mol-ecules in the asymmetric unit. The two uracil units in the same mol-ecule are connected by a pair of strong N-H?O hydrogen bonds. The packing is stabilized by N-H?O, C-H?O and C-H?N inter-actions.

(E)-6-Amino-1,3-dimethyl-5-[(pyridin-2-yl-methyl-idene)amino]-pyrimidine-2,4(1H,3H)-dione.

Project description:In the title compound, C(12)H(13)N(5)O(2), a Schiff-base-derived chelate ligand, the non-aromatic heterocycle and its substituents essentially occupy one common plane (r.m.s. of fitted non-H atoms = 0.0503?Å). The N=C bond is E-configured. Intra-cyclic angles in the pyridine moiety cover the range 117.6?(2)-124.1?(2)°. Intra- and inter-molecular N-H?N and N-H?O hydrogen bonds are observed in the crystal structure, as are intra- and inter-molecular C-H?O contacts which, in total, connect the mol-ecules into a three-dimensional network. The shortest ring-centroid-to-ring-centroid distance of 3.5831?(14)?Å is between the two different types of six-membered rings.
