Project description:The backbone of the title mol-ecule, C(26)H(25)BrN(4)O, is approximately planar: the dihedral angle between the planes of the indoline ring system and the furan ring is 7.68 (14)°.

1-{[(2,3-Dihydro-1H-inden-2-yl)-oxy]meth-yl}quinazoline-2,4(1H,3H)-dione.

Project description:In the title mol-ecule, C(18)H(16)N(2)O(3), the five-membered ring has an envelope conformation, with the substituted C atom deviating by 0.342 (4) Å from the mean plane P calculated for the remainder of the non-H atoms of the 2,3-dihydro-1H-indene fragment. The mean planes of quinazoline-2,4(1H,3H)-dione fragment and P form a dihedral angle of 59.08 (4)°. In the crystal, pairs of N-H⋯O hydrogen bonds link mol-ecules into inversion dimers, and weak C-H⋯O hydrogen bonds and π-π inter-actions between the benzene rings of the quinazoline ring systems [centroid-centroid distance = 3.538 (3) Å] further consolidate the packing.

(E)-5-(2-Nitro-prop-1-en-yl)-2,3-dihydro-1-benzofuran.

Project description:The asymmetric unit of the title compound, C(11)H(11)NO(3), contains two crystallographically independent mol-ecules. The aromatic rings are oriented at a dihedral angle of 56.17?(5)°. The furan rings adopt envelope conformations. Intra-molecular C-H?N inter-actions results in the formation of two six-membered rings with twisted conformations. In the crystal structure, three weak C-H?? inter-actions are found.

(2E)-2-[(2E)-3-Phenyl-prop-2-en-1-yl-idene]-2,3-dihydro-1H-inden-1-one.

Project description:The title indan-1-one derivative, C(18)H(14)O, is planar with an r.m.s. deviation for all 19 non-H atoms of 0.098?Å. The conformation about each of the C=C bonds [1.343?(3) and 1.349?(3)?Å] is E. Supra-molecular layers in the bc plane, mediated by C-H?O and ?-? [ring centroid-centroid distance = 3.5282?(15)?Å] inter-actions, feature in the crystal packing.

1-(Prop-2-yn-yl)indoline-2,3-dione.

Project description:The structure of the title compound, C11H7NO2, is isotypic to that of its homologue, 1-octylindoline-2,3-dione [Qachchachi et al. (2013 ▶). Acta Cryst. E69, o1801]. The indoline ring and the two carbonyl O atoms are approximately coplanar, the largest deviation from the mean plane being 0.021 (1) Å for one of the O atoms. The mean plane through the fused ring system is nearly perpendicular to the propynyl group, as indicated by the N-C-C-C torsion angle of 77.9 (1)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and π-π inter-actions between benzene rings [inter-centroid distance = 3.5630 (10) Å], forming a three-dimensional structure.

2-(2-{[4-Oxo-3-(2-phenyl-eth-yl)-3,4-dihydro-quinazolin-2-yl]sulfan-yl}eth-yl)-2,3-dihydro-1H-isoindole-1,3-dione.

Project description:In the title compound, C(26)H(21)N(3)O(3)S, the quinazolinyl group is essentially planar [r.m.s. deviation for the 10 non-H atoms = 0.057?Å]. The isoindoline-1,3-dione group is linked by an SCH(2)CH(2) chain to the pyrimidinyl C atom that lies between the two N atoms. Also, the phenyl group is linked by a CH(2)CH(2) chain at the N atom adjacent to the carbonyl group. This results in a conformation with these substituents lying to either side of the central quinazolinyl unit, with the former being approximately parallel [dihedral angle = 4.93?(7)°], and the phenyl group being inclined [dihedral angle = 71.61?(9)°] to the central quinazolinyl fused-ring system. In the crystal, mol-ecules are consolidated into a three-dimensional architecture by C-H?O inter-actions, involving all three carbonyl-O atoms, and ?-? inter-actions occurring between the pyrimidinyl and isoindole-benzene rings [inter-centroid distance = 3.5330?(13)?Å].

(Z)-3-(1-Chloro-prop-1-en-yl)-2-methyl-1-phenyl-sulfonyl-1H-indole.

Project description:In the title compound, C18H16ClNO2S, the indole ring system forms a dihedral angle of 75.07?(8)° with the phenyl ring. The mol-ecular structure is stabilized by a weak intra-molecular C-H?O hydrogen bond. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds, forming a chain along [10-1]. C-H?? inter-actions are also observed, leading to a three-dimensional network.

The crystal packing is stabilized by classical inter-molecular O-H?O and O-H?N hydrogen bonds and weak C-H?O hydrogen bonds between the organic mol-ecules and the water mol-ecules.

Project description:In the title compound, C(21)H(18)N(8), the two (benzotriazol-1-yl)methyl groups are located in an anti position with respect to the benzimidazoline moiety.
