N-[2-(3-Methyl-1-oxo-1,2-dihydro-pyrrolo-[1,2-a]pyrazin-2-yl)eth-yl]methane-sulfonamide.

ABSTRACT: In the title compound, C(11)H(15)N(3)O(3)S, the dihedral angle between the five- and six-membered rings is 1.13?(18)°. The ethyl-methane-sulfonamide group is in a (+)synclinal conformation. In the crystal, inter-molecular N-H?O and C-H?O hydrogen-bond inter-actions link mol-ecules into zigzag ribbons parallel to the b axis. The ribbons are further connected by C-H?? inter-actions.

3-[2-(3-Methyl-2-oxo-1,2-dihydro-quinoxalin-1-yl)eth-yl]oxazolidin-2-one.

Project description:The title heterocyclic compound, C(14)H(15)N(3)O(3), is a new synthetic mol-ecule containing oxazolidine and quinoxaline rings. It is built up from two fused six-membered rings linked to a five-membered oxazolidin-2-one ring by a C(2) chain. Both ring systems are essentially planar [maximum deviation = 0.894 (3) Å, r.m.s. deviation = 0.0043 Å]. The structure is held together by van der Waals forces [electrostatic interactions between dipoles, O⋯C = 3.002 (2) Å] between mol-ecules and by weak π-π stacking between symmetry-related mol-ecules, with an inter-planar distance of 3.579 Å and a centroid-centroid distance of 3.800 (1) Å. Inter-molecular C-H⋯O hydrogen bonds are also observed in the crystal structure.

Project description:In the title solvate, C(11)H(11)N(3)O(2)S·CH(3)NO(2), the dihedral angle between the benzene ring and the N-containing ring is 85.94 (11)°, and an approximate V shape arises for the sulfonamide mol-ecule. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds and weak C-H⋯O inter-actions link the sulfonamide mol-ecules into a three-dimensional network. The nitro-methane solvent mol-ecules are located in the inter-stitial sites in the sulfonamide network.

2-(3-Chloro-1,2-dihydro-pyrazin-2-yl-idene)malononitrile.

Project description:In the crystal structure of the title compound, C(7)H(3)ClN(4), neighbouring mol-ecules are linked via pairs of N-H?N hydrogen bonds into inversion dimers, thereby forming an R(2) (2)(12) ring motif. With respective average deviations from planarity of 0.009?(1) and 0.006?(1)?Å, the pyrazine skeleton and the malononitrile fragment are oriented at an angle of 6.0?(1)° with respect to each other. The mean planes of the pyrazine ring lie either parallel or are inclined at an angle of 68.5?(1)° in the crystal structure.

(Phen-yl)(3-phenyl-sulfonyl-1,2-dihydro-pyrrolo-[1,2-a]quinoxalin-1-yl)methanone.

Project description:In the title mol-ecule, C(24)H(18)N(2)O(3)S, the 13-atom ring system comprising the quinoxaline and fused five-membered ring exhibits an r.m.s. deviation from coplanarity of 0.039 Å, with a maximum deviation of 0.0710 (10) Å for the PhCO-bearing C atom of the five-membered ring. The 10-membered C(8)N(2) quinoxaline ring system has an r.m.s. deviation from coplanarity of 0.022 Å, with a maximum deviation of 0.0403 (9) Å for the C atom involved in the C=C bond in the five-membered ring. The three atoms of the five-membered ring fused to the quinoxaline ring system show deviations of up to 0.118 (2) Å for the PhCO-bearing C atom. C-N bond distances in the quinoxaline ring system of the title mol-ecule deviate from those in unsubstituted quinoxaline. In particular, the two C-N distances to the N atom involved in the five-membered ring are essentially equal, with values of 1.3786 (17) and 1.3773 (16) Å, unlike the difference of nearly 0.06 Å in quinoxaline.
