3-(4-Meth-oxy-phen-yl)pyrido[2,3-b]pyrazine.

Project description:In the title mol-ecule, C(14)H(11)N(3)O, the benzene ring is twisted by 14.0?(2)° from the plane through the fused ring system. In the crystal, ?-? inter-actions [centroid-centroid distances = 3.609?(1), 3.639?(1) and 3.735?(1)?Å] form stacks of mol-ecules propagating along the b axis. The crystal packing is further stabilized by weak inter-molecular C-H?O and C-H?N hydrogen bonds.

Crystal structures of 2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine and 7-bromo-2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine.

Project description:The crystal structures of 2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine, C15H9N3S2 (1), and 7-bromo-2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine, C15H8BrN3S2 (2), are discussed. Both mol-ecules crystallize in space group P21/c. In 1, the thienyl rings are inclined to the mean plane of the pyrido-pyrazine moiety by 6.16?(7) and 86.66?(8)°, where as in 2 the corresponding dihedral angles are 33.29?(11) and 19.84?(9)°. The pyrido-pyrazine moiety is relatively planar in 1 with the two rings being inclined to each other by 1.33?(7)°. In 2, however, the pyrido-pyrazine moiety is buckled with the corresponding dihedral angle being larger at 8.78?(10)°. In the crystal of 1, the packing creates inter-secting bilayers; the layering results from the pyrido-pyrazine moieties being engaged in offset ?-stacking, where the inter-planar distance is 3.431?(9)?Å with an offset 1.14?Å. In the crystal of 2, the mol-ecules pack head-to-head and are linked by a series of C-H?Br and C-H?N inter-molecular inter-actions, forming layers parallel to the ab plane.

2,3-Bis(thio-phen-2-yl)pyrazine-[2,3-f][1,10]phenanthroline.

Project description:The mol-ecule of the title compound, C(22)H(12)N(4)S(2), shows no crystallographic symmetry. The thiophene rings form different dihedral angles [40.15?(9) and 15.43?(10)°] with the pyrazine ring. A strong ?-? stacking inter-action occurs between adjacent pyrazine-[2,3-f][1,10]phenanthroline units with an inter-planar distance of 3.4352?(16)?Å.

2,4,6-Tris-(4-fluoro-phen-yl)-2-(1-pyrid-yl)-boroxine.

Project description:Crystals of the title compound, C(23)H(17)B(3)F(3)NO(3), were obtained unintentionally by slow evaporation of a chloro-form solution of the preformed boroxine-pyridine adduct. The mol-ecule contains three fluoro-substituted benzene rings, each bonded to one of the three B atoms of a six-membered boroxine ring. A pyridyl ring is also bound to one of the B atoms through a Lewis acid-base inter-action. The binding of the pyridyl substituent causes the otherwise planar boroxine ring to twist, resulting in a maximum torsion angle within the ring of 17.6?(2)°.
