Tris(2,2′-bipyridine-κ²N,N′)cobalt(II) bis­(hexa­fluoridophosphate)

In the title compound, [Co(C₁₀H₈N₂)₃](PF₆)₂, the Co^II atom is coordinated by the six N atoms of three 2,2′-bipyridyl ligands and adopts a highly distorted octa­hedral geometry. The crystal used was a merohedral twin, the refined ratio of twin components being 0.820 (1):0.180 (1). The crystal structure features weak C—H...F inter­actions, forming a three-dimensional network.

2-(2,6-Di­chloro­phen­yl)-1-pentyl-4,5-diphenyl-1H-imidazole

The title compound, C₂₆H₂₄Cl₂N₂, crystallizes with two independent mol­ecules (1 and 2) in the asymmetric unit. In mol­ecule 1, the two phenyl and 2,6-di­chloro­phenyl rings are inclined to the imidazole ring at angles of 74.12 (14), 26.13 (14) and 67.30 (14)°, respectively. In mol­ecule 2, due to the different mol­ecular environment in the crystal, the corresponding angles are different, viz. 71.72 (15), 16.14 (15) and 80.41 (15)°, respectively. In the crystal, mol­ecules 1 and 2 are linked by C—H...Cl inter­actions, and inversion-related 2 mol­ecules are linked by C—H...π inter­actions. There are no other significant inter­molecular inter­actions present.

(2Z)-3-(2,4-Di­chloro­phen­yl)-3-hy­droxy-N-phenyl­prop-2-ene­thio­amide

In the title mol­ecule, C₁₅H₁₁Cl₂NOS, the dihedral angle between the phenyl and benzene rings is 72.24 (1)°. In the crystal, pairs of N—H...S hydrogen bonds form dimers with twofold rotational symmetry. The dimers are connected by weak C—H...O hydrogen bonds, forming a two-dimensional network parallel to (001). An intra­molecular O—H...S hydrogen bond is also observed.

2-(4-Chloro­phen­yl)-1-pentyl-4,5-di­phenyl-1H-imidazole

In the title compound, C₂₆H₂₅ClN₂, the phenyl rings and the 2-(4-chloro­phen­yl) group make dihedral angles of 30.03 (11), 67.49 (12) and 41.56 (11)°, respectively, with the imidazole ring. In the crystal, the mol­ecules inter­act with each other via very weak C—H...π contacts, forming layers parallel to (110).

2-(4-Bromo­phen­yl)-1-pentyl-4,5-diphenyl-1H-imidazole

The title compound, C₂₆H₂₅BrN₂, is isomorphous with the chloro derivative [2-(4-chloro­phen­yl)-1-pentyl-4,5-diphenyl-1H-imidazole; Mohamed et al. (2013). Acta Cryst. E69, o846-o847]. The two phenyl rings and the 4-bromo­phenyl ring are oriented at dihedral angles of 30.1 (2), 64.3 (3) and 42.0 (2)°, respectively, with respect to the imidazole ring. In the crystal, mol­ecules stack in columns along the b-axis direction, however, there are no significant inter­molecular inter­actions present.

2-(3,4-Di­meth­oxy­phen­yl)-1-pentyl-4,5-diphenyl-1H-imidazole

The central imidazole ring in the title compound, C₂₈H₃₀N₂O₂, makes dihedral angles of 28.42 (13), 71.22 (15) and 29.50 (14)°, respectively, with the phenyl rings in the 4- and 5-positions and the 3,4-di­meth­oxy­phenyl group. In the crystal, mol­ecules are linked by C—H...O and C—H...N hydrogen bonds, weak π–π stacking inter­actions [centroid–centroid distance = 3.760 (2) Å] and C—H...π contacts, forming a three-dimensional network.
