Bis[4-(diphenyl­methyl­eneamino)phen­yl]methanone

(5-Benzoyl-2-methyl-4-{[1-(pyridin-4-yl)-1H-1,2,3-triazol-4-yl]meth­oxy}-1-benzofuran-7-yl)(phen­yl)methanone

The crystal structure of the title compound, C(31)H(22)N(4)O(4), features weak C-H⋯O inter-actions. The dihedral angle between the fused benzene and furan rings is 2.49 (15)°, while that between the triazole and pyridine rings is 10.23(18)°.

[4-(All­yloxy)phen­yl](phen­yl)methanone

The structure of the title compound, C16H14O2, features a dihedral angle of 54.4 (3)° between the aromatic rings. The allyl group is rotated by 37.4 (4)° relative to the adjacent benzene ring. The crystal packing is characterized by numerous C-H⋯O and C-H⋯π inter-actions. Most of these inter-actions occur in layers along (011). The layers are linked by C-H⋯π inter-actions along [100], forming a...

A second monoclinic polymorph of (E)-phen­yl(pyridin-2-yl)methanone oxime

The title compound, C(12)H(10)N(2)O, a second monoclinic poly-morph of (E)-phen-yl(pyridin-2-yl)methanone oxime crystallizes in the space group P2(1)/n (Z = 4). The previously reported polymorph [Taga et al. (1990 ▶). Acta Cryst. C46, 2241-2243] occurs in the space group C2/c (Z = 8). In the crystal, pairs of bifurcated O-H⋯(N,O) hydrogen bonds link the mol-ecules into inversion dimers. The dim...

{5-Chloro-2-[(4-chloro­benzyl­idene)­amino]­phen­yl}(phen­yl)methanone

In the title compound, C(20)H(13)Cl(2)NO, the C=N bond adopts an E conformation. The chloro-substituted rings form a dihedral angle of 11.99 (9)° with each other and form dihedral angles of 74.95 (9) and 83.26 (10)° with the unsubstituted ring. In the crystal, mol-ecules are connected into dimers by pairs of weak C-H⋯O hydrogen bonds and the dimers are arranged in columns parallel to the a axis.
