2-Methyl-3,5,6-triphenyl-2,3-dihydro-pyrazine.

ABSTRACT: In the title mol-ecule, C(23)H(20)N(2), the heterocyclic ring adopts a screw-boat conformation, with all substituents equatorial. The phenyl ring at position 3 makes dihedral angles of 78.12?(15) and 72.67?(15)°, respectively, with the phenyl rings at positions 5 and 6; the dihedral angle between the phenyl rings at positions 5 and 6 is 67.32?(14)°. A C-H?? inter-action is present in the crystal structure.

2-Ethyl-3,5,6-triphenyl-pyrazine.

Project description:In the title mol-ecule, C(24)H(20)N(2), the pyrazine ring is significantly distorted from planarity, presumably due to steric crowding, and its conformation is well described as a flattened twist-boat. The benzene ring adjacent to the ethyl group forms dihedral angles of 53.79?(13) and 85.47?(12)° with the other benzene rings; the dihedral angle between adjacent benzene rings is 57.90?(12)°. The ethyl group is disordered over two positions; the site-occupancy factor of the major component is 0.546?(4). No hydrogen bonds are found in the crystal structure.

5,6-Di-2-thienyl-2,3-dihydro-pyrazine.

Project description:In the title compound, C(12)H(10)N(2)S(2), which was synthesized by the reaction of 2,2'-thenil and ethyl-enediamine, the dihedral angle between the two thio-phene rings is 66.33?(9)°. In the crystal structure, inter-molecular C-H?N hydrogen bonds link the mol-ecules into infinite chains along the b axis and weak C-H?? inter-actions may further stabilize the structure.

2-Methyl-3-(4-methyl-phen-yl)-5,6-diphenyl-2,3-dihydro-pyrazine.

Project description:In the title mol-ecule, C(24)H(22)N(2), four atoms (N-C-C-N) of the heterocyclic ring, with their attached H atoms, and all atoms of the methyl group, are disordered over two positions; the site-occupancy factor of the major component is 0.713?(6). The major disorder component of the heterocyclic ring adopts a half-chair conformation, with all substituents equatorial. The benzene ring adjacent to the methyl group forms dihedral angles of 79.68?(11) and 80.92?(11)° with the phenyl rings; the dihedral angle between adjacent phenyl rings is 59.10 (11)°. The crystal structure features three C-H?? inter-actions.

Methyl pyrido[2,3-b]pyrazine-3-carboxyl-ate.

Project description:The asymmetric unit of the title compound, C(9)H(7)N(3)O(2), is composed of two independent mol-ecules. The crystal structure is stabilized by C-H⋯O and C-H⋯N hydrogen bonds, forming a three-dimensional network. The crystal structure also features pyrazine-pyrazine π-π inter-actions [centroid-centroid distance = 3.6994 (5) Å] and also pyridine-pyrazine π-π inter-actions [centroid-centroid distance = 3.6374 (5) Å].

2,3,5-Triphenyl-pyrazine.

Project description:In the title mol-ecule, C(22)H(16)N(2), the pyrazine ring deviates very slightly from planarity [maximum deviation 0.044?(3)?Å], tending towards a twist-boat conformation. The phenyl ring at position 3 makes dihedral angles of 64.0?(2) and 45.8?(2)°, respectively, with the phenyl rings at positions 2 and 5. The dihedral angle between the phenyl rings at positions 2 and 5 is 49.7?(2)°. A C-H?? inter-action is found in the crystal structure, but no classical hydrogen bonds form.

1-Methyl-2,3-dihydro-1H-benzimidazole-2-selone.

Project description:The title compound C(8)H(8)N(2)Se, is the product of the reaction of 2-chloro-1-methyl-benzimidazole with sodium hydro-selenide. The mol-ecule is almost planar (r.m.s. deviation = 0.041 Å) owing to the presence of the long chain of conjugated bonds (Se=C-NMe-C=C-C=C-C=C-NH). The C=Se bond length [1.838 (2) Å] corresponds well to those found in the close analogs and indicates its pronounced double-bond character. In the crystal, mol-ecules form helicoidal chains along the b axis by means of N-H⋯Se hydrogen bonds.

Project description:In the title compound, C(22)H(26)N(2)O(5), the central 1,4-dihydro-pyrazine ring adopts a boat conformation, while the benzene ring and the two disordered components of the furan ring are inclined at angles of 77.9 (5) and 61.9 (7)°. Three of the C atoms of the furan ring are disordered over two positions with occupancies of 0.655 (18) and 0.345 (18). In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains propagating in [010].

Project description:The seven-membered fused-ring in the title compound, C(10)H(10)N(2)O·H(2)O, adopts a boat conformation (with the two phenyl-ene C atoms representing the stern and the methyl-ene C atom the prow). In the crystal, two benzodiazepinone mol-ecules are linked about a center of inversion by diazepine-carbonyl N-H?O hydrogen bonds. The dimers are further linked by water-diazepine O-H?N hydrogen bonds, forming a linear chain.
