1,1',3,3',5,5'-Hexamethyl-spiro-[furo[2,3-d]pyrimidine-6(5H),5'-pyrimidine]-2,2',4,4',6'(1H,3H,1'H,3'H,5'H)-penta-one.

ABSTRACT: In the title mol-ecule, C(15)H(18)N(4)O(6), the fused 2,3-dihydro-furan ring has an envelope conformation and the spiro pyrimidine ring has a half-chair conformation. In the crystal, short inter-molecular O?C contacts of 2.835?(4) and 2.868?(4)?Å between the carbonyl groups indicate the existence of electrostatic inter-actions, which link the mol-ecules into corrugated sheets parallel to the ab plane.

6,6'-Diamino-1,1',3,3'-tetra-methyl-5,5'-(4-chloro-benzyl-idene)bis-[pyrimidine-2,4(1H,3H)-dione].

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.

Crystal structure of 5,5-bis-(4-methyl-benz-yl)pyrimidine-2,4,6(1H,3H,5H)-trione monohydrate.

Project description: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 further alternately stacked along the b axis and inter-connected via C-H⋯πar-yl inter-actions.

Project description:The title compound, C(30)H(38)O(8), possess C(i) symmetry, with the inversion center situated at the center of the bridging C-C bond. In the crystal structure, mol-ecules are held together by C-H⋯O inter-actions.

1,1'-Di-tert-butyl-2,2',3,3',4,4',5,5'-octa-ethyl-1,1'-bis-tannole.

Project description:The title compound, [Sn(2)(C(4)H(9))(2)(C(12)H(20))(2)], has two 1-stannacyclo-penta-diene skeletons related by inversion symmetry located at the mid-point of the Sn-Sn bond [2.7682 (2) Å]. Thus, the asymmetric unit comprises one half-mol-ecule. The planarity of the stannacyclo-penta-diene ring is illustrated by the dihedral angle of 0.3 (1)°, defined by the C(4) and C-Sn-C planes. To avoid steric repulsion, the two stannole rings are oriented in an anti fashion through the Sn-Sn bond. These structural features are similar to those of other bis-tannoles.

Project description:In the title compound, C(23)H(26)O(4), there is a dihedral angle of 83.7 (6)° between the two benzene rings. The five-membered rings have chair conformations.

Diammonium 1,1',3,3'-tetra-methyl-2,2',4,4',6,6'-hexa-oxoperhydro-5,5'-bipyrimidine-5,5'-diide monohydrate.

Project description:In the title hydrated salt, 2NH(4) (+)·C(12)H(12)N(4)O(6) (2-)·H(2)O, the two hexa-hydro-pyrimidine rings in the dianion are inclined to one another at a dihedral angle of 62.76?(5)°. In the crystal structure, the anions and water mol-ecules are linked into sheets parallel to the bc plane by inter-molecular O-H?O hydrogen bonds and sustained by C-H?O contacts. The linking of the anions and water mol-ecules with the cations by N-H?O hydrogen bonds creates a three-dimensional extended network. The crystal structure is further stabilized by very weak C-H?? inter-actions.

5-Fluoro-1-(penta-noyl)pyrimidine-2,4(1H,3H)-dione.

Project description:The penta-noyl group and the 5-fluoro-uracil moiety of the title compound, C(9)H(11)FN(2)O(3), are essentially coplanar, with the penta-noyl carbonyl group oriented towards the ring CH group and away from the nearer ring carbonyl group. In the crystal structure, two inversion-related mol-ecules form a dimer structure, in which two N-H?O hydrogen bonds generate an inter-molecular R(2) (2)(8) ring. In addition, there are intra- and inter-molecular C-H?O inter-actions.

Bruceolline D: 3,3-dimethyl-1H,4H-cyclo-penta-[b]indol-2(3H)-one.

Project description:The title compound, C13H13NO, crystallizes with four independent mol-ecules in the asymmetric unit. The 12-membered penta-[b]indole rings are essentially planar, with maximum deviations ranging from 0.034 (4) to 0.036 (4) Å in the four unique mol-ecules. In the crystal, weak C-H⋯O inter-actions are observed, which link the mol-ecules into chains along [010].

(E)-3,3',4,4',7,7',8,8'-Octa-methyl-2H,2'H-1,1'-bi(cyclo-penta-[fg]acenaphthyl-enyl-idene)-2,2',5,5',6,6'-hexa-one dichloro-methane monosolvate.

Project description:The title compound, C(36)H(24)O(6)·CH(2)Cl(2), is a dimer of two essentially planar (r.m.s., deviations of fitted plane of 14 pyracene C atoms = 0.0539 and 0.0543 Å) tetra-cyclic pyracene frameworks (each with four methyl groups and three carbonyl groups on the peripheral carbon atoms) twisted along a central C=C bond with an angle of 50.78 (3)° at 90 K. There are notably long Csp(2)-Csp(2) bonds associated with the carbonyl groups, the longest being 1.601 (3) Å between two carbonyl C atoms. There are also intermolecular carbonyl⋯carbonyl interactions of both parallel and antiparallel types, with C⋯O distances in the range 3.041 (3) to 3.431 (2) Å. This compound is of inter-est with respect to the synthesis of fullerene fragments, such as corannulene and semibuckminsterfullerene derivatives (or 'buckybowls'), and is a side product of the previously reported oxidation reaction. Structural details, such as planarity analysis of fused rings, out-of-plane deviation of substituents, inter-molecular inter-actions, and longer than typical bond lengths, will be discussed as well as comparisons to structurally related compounds.
