Poly[di-?-chlorido-?-(1,2,3,9-tetra-hydro-pyrrolo-[2,1-b]quinazolin-9-one-?N:O)-mercury(II)].

ABSTRACT: In the crystal structure of the title two-dimensional network, [HgCl(2)(C(11)H(10)N(2)O)](n), the asymmetric unit consists of HgCl(2) dumbbells and one mol-ecule of the quinazoline unit. Pseudo-octa-hedrally coordinated Hg(II) cations are chloride-bridged via a crystallographic inversion centre leading to different Hg-Cl bonds (short and long) and linked by other Cl atoms via translation along the a axis. The quinazoline ligands connect the Hg-Cl-Hg-Cl chains by N and O atoms along the b axis, forming the two-dimensional network structure. The crystal structure is stabilized by weak non-classical C-H?Cl hydrogen bonds and aromatic ?-? stacking inter-actions [centroid-centroid distances = 3.942?(4) and 3.621?(4)?Å].

(E)-3-[4-(Dimethyl-amino)-benzyl-idene]-2,3-di-hydro-1H,9H-pyrrolo-[2,1-b]quinazolin-9-one.

Project description:The title compound, C(20)H(19)N(3)O, was obtained by condensation of 2,3-dihydro-1H,9H-pyrrolo-[2,1-b]quinazolin-9-one (alkaloid de-oxy-vasicinone, isolated from Peganum Harmala) with 4-(dimethyl-amino)-benzaldehyde in the presence of sodium methoxide. The 2,3-dihydro-1H,9H-pyrrolo-[2,1-b]quinazolin-9-one part of the mol-ecule is roughly planar (r.m.s. deviation = 0.0178?Å) and is essentially coplanar with the benzil-idene ring (r.m.s. deviation = 0.0080?Å), forming a dihedral angle of 5.0?(1)°. The crystal structure is stabilized by two aromatic ?-? stacking inter-actions observed between the benzene rings of neighboring mol-ecules [centroid-centroid distance = 3.7555?(19)?Å.

catena-Poly[[bis[quinazolin-4(3H)-one-?N]cadmium(II)]-di-?-chlorido].

Project description:The asymmetric unit of the title compound, [CdCl(2)(C(8)H(6)N(2)O)(2)](n), consists of one mol-ecule of the 3H-quinazolin-4-one ligand, one Cd(2+) cation, which is located on a twofold axis, and one chlorido ligand in a general position. The latter bridges metal cations, forming a one-dimensional polymer along the b axis. The Cd?Cd distance along the chain is 3.7309?(7)?Å. The octa-hedral coordination around the metal is completed by two ligands in a trans axial geometry which coordinate through the N atom in 1 position. Moderately strong classical N-H?O hydrogen bonds around crystallographic inversion centers cross-link adjacent polymeric chains.

3-Hydr-oxy-1,2,3,9-tetra-hydro-pyrrolo[2,1-b]quinazolin-4-ium chloride dihydrate: (+)-vasicinol hydro-chloride dihydrate from Peganum harmala L.

Project description:The title compound, C(11)H(13)N(2)O(+)·Cl(-)·2H(2)O, the dihydrate of (+)-vasicinol hydro-chloride, is a pyrrolidinoquinazoline alkaloid. It was isolated from the ethyl acetate fraction of the leaves of Peganum harmala L. The pyrrolidine ring has an envelope conformation with the C atom at position 2 acting as the flap and the C atom at position 3, carrying the hydroxyl substituent, has an S configuration. The absolute configuration was determined as a result of the anomalous scattering of the Cl atom. In the crystal structure, mol-ecules stack along the a axis, connected to one another via inter-molecular O-H?Cl and N-H?Cl hydrogen bonds, forming approximately triangular-shaped R(2) (1)(7) rings, and O-H?Cl and O-H?O hydrogen bonds, forming penta-gonal-shaped R(5) (4)(10) rings. The overall effect is a ribbon-like arrangement running parallel to the a axis.

5-Methyl-1,2,3,3a-tetra-hydro-benzo[e]pyrrolo-[2,1-b][1,3]oxazepin-10(5H)-one.

Project description:The asymmetric unit of the title compound, C(13)H(15)NO(2), the main product of a photoreaction, contains two crystallographically independent mol-ecules. In both mol-ecules, the conformation of the seven-membered ring is twist sofa and that of the five-membered rings is envelope. In the crystal, mol-ecules are linked by weak inter-molecular C-H?O hydrogen bonds.

Project description:The structure of the title compound, C(19)H(19)NO(2), contains a seven-membered ring, which is fused to one five- and one six-membered ring, and carries a tolyl substituent. The two benzene rings are oriented relative to each other at a dihedral angle of 86.90?(7)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H?O hydrogen bonds.

(S)-Ethyl 1,2,3,9-tetra-hydro-pyrrolo[2,1-b]quinazoline-1-carboxyl-ate.

Project description:The title chiral compound, C(14)H(16)N(2)O(2), was prepared by esterification of (S)-1,2,3,9-tetra-hydro-pyrrolo[2,1-b]quinazol-in-1-carboxylic acid in the presence of HCl/EtOH. In the mol-ecule, the quinazoline ring is non-planar and exhibits a distorted half-chair conformation, while the five-membered ring shows a typical envelope conformation. Inter-molecular C-H?N hydrogen bonding helps to stabilize the crystal structure.

(E)-3-Propoxymethyl-idene-2,3-dihydro-1H-pyrrolo[2,1-b]quinazolin-9-one monohydrate.

Project description:The title compound, C(15)H(16)N(2)O(2)·H(2)O, was synthesized via the alkyl-ation of 3-hydroxy-methyl-idene-2,3-dihydro-1H-pyrrolo[2,1-b]quinazolin-9-one with n-propyl iodide in the presence of sodium hydroxide. The organic mol-ecule and the water mol-ecule both lie on a crystallographic mirror plane. In the crystal structure, inter-molecular O-H?O and O-H?N hydrogen bonds link the components into extended chains along [100].

Crystal structure and Hirshfeld surface analysis of bis-(6,7,8,9-tetra-hydro-11H-pyrido[2,1-b]quinazolin-5-ium) tetra-chlorido-zincate.

Project description:The title compound, (C12H15N2)2[ZnCl4], is a salt with two symmetrically independent, essentially planar heterocyclic cations and a slightly distorted tetra-hedral chloro-zincate dianion. N-H⋯Cl hydrogen bonds link these ionic constituents into a discrete aggregate, which comprises one formula unit. The effect of hydrogen bonding is reflected in the minor distortions of the [ZnCl4]2- moiety: distances between the cation and chlorido ligands engaged in classical hydrogen bonds are significantly longer than the others. Secondary inter-actions comprise C-H⋯π hydrogen bonding and weak π-π stacking. A Hirshfeld surface analysis indicates that the most abundant contacts in packing stem from H⋯H (47.8%) and Cl⋯H/H⋯Cl (29.3%) inter-actions.

Stereochemistry of the methyl-idene-bridged quinazoline-iso-quinoline alkaloid 3-{[6,7-dimeth-oxy-1-(4-nitro-phen-yl)-1,2,3,4-tetra-hydro-isoquinolin-2-yl]methyl-idene}-1,2,3,9-tetra-hydro-pyrrolo-[2,1-b]quinazolin-9-one methanol monosolvate.

Project description:Two potentially bioactive fragments, namely a tricyclic quinazoline derivative with an exocyclic alkene moiety and a substituted iso-quinoline, are coupled to give 3-{[6,7-dimeth-oxy-1-(4-nitro-phen-yl)-1,2,3,4-tetra-hydro-isoquinolin-2-yl]methyl-idene}-1,2,3,9-tetra-hydro-pyrrolo-[2,1-b]quinazolin-9-one. The target product crystallizes as a methanol solvate, C29H26N4O5·CH4O, and is E configured. The alternative Z isomer would necessarily imply either considerable twist about the central double bond or very unfavourable intra-molecular contacts between sterically more demanding substituents. The main residue and the co-crystallized solvent mol-ecule aggregate to discrete pairs via a classical O-H⋯O hydrogen bond with a distance of 2.8581 (7) Å between the methanol OH donor and the quinazolinone O=C acceptor.

(3aR*,5R*)-5-(4-Chloro-phen-yl)-1,2,3,3a-tetra-hydro-benzo[e]pyrrolo-[2,1-b][1,3]ox-azepin-10(5H)-one.

Project description:The title compound, C(18)H(16)ClNO(2), is the main product of a photoreaction. The two benzene rings make a dihedral angle of 86.40?(2)° with each other. The 1,3-oxazepine C atom to which the 4-chloro-phenyl group is attached and the C atom of the 4-chloro-phenyl group attached to the 1,3-oxazepine ring are chiral C atoms, but the crystal is a racemate in which the enanti-omers are linked by a pair of weak inter-molecular C-H?O hydrogen bond, forming an inversion dimer.
