ABSTRACT: The title compound, C(20)H(19)N(3)O(3)·C(3)H(7)NO, was synthesized by the reaction of 6-amino-pyrimidine-2,4(1H,3H)-dione and 4-methyl-benzaldehyde with 5,5-dimethyl-1,3-cyclo-hexa-nedione in 1-butyl-3-methyl-imidazolium bromide at 363?K. The pyrimidine ring adopts a half-chair conformation while the six-membered ring fused to the pyridine ring adopts a skew-boat conformation. The dihedral angle between the pyridine ring and the attached benzene ring is 2.38(8)°

2-Chloro-8,8-dimethyl-8,9-dihydro-7H-chromeno[2,3-b]quinoline-10,12-dione.

Project description:The asymmetric unit of the title compound, C(18)H(14)ClNO(3), contains two independent mol-ecules (A and B). In both mol-ecules, the cyclo-hexa-none ring has a chair conformation. The dihedral angles between the pyran ring and the pyridine and chloro-phenyl rings are 2.13?(9) and 2.19?(9)°, respectively, in A, and 0.82?(9) and 1.93?(9)°, respectively, in B. The carbonyl O atoms deviate from the pyran and benzene rings to which they are attached by -0.092?(2) and 0.064?(2)?Å, respectively, in A, and by -0.080?(2) and -0.063?(2)?Å, respectively, in B. In the crystal, the A mol-ecules are linked via C-H?O hydrogen bonds, forming double-stranded chains along [100]. They lie parallel to the double-stranded chains formed by the B mol-ecules, which are also linked via C-H?O hydrogen bonds. The chains stack up the c axis in an -A-A-B-B-A-A- manner, with a number of ?-? inter-actions involving A and B mol-ecules; the centroid-centroid distances vary from 3.4862?(11) to 3.6848?(11)?Å

8,8-Dimethyl-8,9-dihydro-7H-chromeno[2,3-b]quinoline-10,12-dione.

Project description:In the title compound, C(18)H(15)NO(3), the fused benzopyran and pyridine rings are essentially coplanar [r.m.s. deviation = 0.0533?Å with a maximum deviation of 0.080?(1)?Å for a benzene C atom].

The dihedral angle between the mean planes of the pyran and cyclo-hexa-none rings is 12.95?(6)°. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds, leading to chains running along [011].

Acetoguanamine N,N-dimethyl-formamide solvate.

Project description:The structure of acetoguanamine (or 2,4-diamino-6-methyl-1,3,5-triazine) has been determined as the N,N-dimethyl-formamide solvate, C(4)H(7)N(5)·C(3)H(7)NO.

Project description:The structure of the title uric acid derivative, C(7)H(8)N(4)O(5), from human kidney stones, is characterized by the C and O atoms of one of the two hy-droxy-methyl groups being disordered nearly equally over three different sites. In the crystal, mol-ecules are connected by a three-dimensional hydrogen-bonding scheme though they look stacked in planes nearly parallel to ([Formula: see text]04).

Project description:In the title compound, [Cu(C(8)H(5)Cl(2)N(3)OS)(C(3)H(7)NO)]·C(3)H(7)NO, the Cu(II) atom is coordinated in a slightly distorted square-planar geometry by an O, an S and an N atom from the tridentate ligand 3,5-dichloro-salicylaldehyde thio-semi-carb-azonate ligand and one O atom from dimethyl-formamide.
