3-Ethyl-5-(4-meth-oxy-phen-oxy)-2-(pyridin-4-yl)-3H-imidazo[4,5-b]pyridine.

ABSTRACT: In the title compound, C(20)H(18)N(4)O(2), the imidazopyridine fused ring system is almost perpendicular to the benzene ring [dihedral angle = 87.6?(5)°]. The pyridine ring makes a dihedral angle of 35.5?(5)° with the mean plane of the imidazopyridine fragment. The crystal structure is stabilized by an aromatic ?-? stacking inter-action between the phenyl rings of neighbouring mol-ecules [centroid-centroid distance = 3.772?(2)?Å, inter-planar distance = 3.546?(2)?Å and slippage = 1.286?(2)?Å].

In the title compound, C(20)H(18)N(4)O(2), the imidazopyridine fused ring system is almost perpendicular to the benzene ring [dihedral angle = 87.6 (5)°]. The pyridine ring makes a dihedral angle of 35.5 (5)° with the mean plane of the imidazopyridine fragment. The crystal structure is stabilized by an aromatic π-π stacking inter-action between the phenyl rings of neighbouring mol-ecules [centroid-centroid distance = 3.772 (2) Å, inter-planar distance = 3.546 (2) Å and slippage = 1.286 (2) Å]. ...[more]

6-Bromo-1,3-bis-[(1,3-dioxolan-2-yl)meth-yl]-1H-imidazo[4,5-b]pyridin-2(3H)-one.

Project description:In the title compound, C14H16BrN3O5, the N atoms adjacent to the carbonyl group in the five-membered ring are substituted by (1,3-dioxolan-2-yl)methyl groups. The fused ring system is essentially planar, with the largest deviation from the mean plane being 0.014 (2) Å for the C atom bearing the Br atom. The first oxolane ring, attached on the side of the N atom belonging to the pyridine ring, has an envelope conformation with one of the O atoms as the flap, whereas the second oxolane ring displays a twisted boat conformation. The two oxolane rings display envelope and twisted boat conformations. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, building chains parallel to the a-axis direction.

3-[(1-Benzyl-1H-1,2,3-triazol-5-yl)meth-yl]-6-bromo-2-phenyl-3H-imidazo[4,5-b]pyridine.

Project description:There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(22)H(17)BrN(6). The dihedral angles between the imidazo[4,5-b]pyridine mean plane and the phenyl rings are 20.4 (2) and 24.0 (2)° in the two mol-ecules. The orientation of triazoles compared to the imidazo[4,5-b]pyridine system is almost the same in both mol-ecules, with dihedral angles of 64.2 (2) and 65.1 (2)°. However, the main difference between the two mol-ecules lies in the arrangement of the phenyl groups compared to imidazo[4,5-b]pyridine in each mol-ecule. Indeed, in the first mol-ecule the dihedral angle between the plane of the phenyl ring and that of the imidazo[4,5-b]pyridine system is 67.7 (2)°, while in the second mol-ecule the plane of the phenyl ring is almost perpendicular to that of the imidazo[4,5-b]pyridine system with a dihedral angle of 86.0 (2)°.

Project description:In the title compound, C(13)H(9)Br(2)N(3)O, the mol-ecular skeleton, influenced by an intra-molecular O-H?N hydrogen bond, is roughly planar, with a mean deviation of 0.033?Å.

Weak inter-molecular ?-? inter-actions [centroid-centroid distances = 3.760?(3) and 3.723?(3)?Å] further consolidate the packing.

Project description:In the title compound, C(16)H(16)N(4)OS, the dihedral angle between the pyridine and benzene rings is 81.08 (6)°.

Project description:The title mol-ecule, C(17)H(14)F(3)NO(4), consists of two nearly planar fragments, viz. the 2-benzyl-oxypyridine (r.m.s. deviation 0.016?Å) and (E)-3-meth-oxy-prop2-enoic (r.m.s. deviation 0.004?Å) units, which form a dihedral angle of 84.19?(7)°. In the crystal, pairs of O-H?O hydrogen bonds link mol-ecules into dimers that are further connected by C-H?O and C-H?F inter-actions into (001) layers. In addition, ?-? stacking inter-actions are observed within a layer between the pyridine and benzene rings [centroid-centroid distance = 3.768?(2)?Å]. The F atoms of the trifluoro-methyl group are disordered over two sets of sites in a 0.53?(4):0.47?(4) ratio.
