4,5‐Bis(2‐tert‐butyl­phenoxy)­phthalo­nitrile

The title compound, C28H28N2O2, contains three aromatic rings, which are not coplanar and which are distorted from ideal C2v symmetry. The crystal structure involves four intramolecular C—H⋯O hydrogen bonds.

4-Amino-3,5-diethyl-4H-1,2,4-triazole at 100 K: chains of edge-fused R(4)(4)(10) and R(4)(4)(20) rings.

The title compound, C(6)H(12)N(4), has four crystallographically independent molecules in the asymmetric unit. Intermolecular N-H...N hydrogen bonds involving amino groups and triazole N atoms form a three-dimensional framework involving R(4)(4)(10) and R(4)(4)(20) rings. The hydrogen bonding is supported by weak C-H...pi interactions.

1,3‐Bis(3,4‐di­cyano­phenoxy)­benzene

The title compound, C22H10N4O2, has been designed and synthesized as a precursor of dye pigments.

4-(2-Benzoyl-5-methoxyphenoxy)benzene-1,2-dicarbonitrile

The title compound, C22H14N2O3, contains three benzene rings, pairs of which form dihedral angles of 55.37 (5), 68.47 (4) and 82.82 (4)°. The average C—O—C angle is 119.0 (1)°.

4-(2-Methoxy-4-methyl­phenoxy)­phthalo­nitrile

In the title compound, C16H12N2O2, the dihedral angle between the two benzene rings is 85.53 (5)°. The crystal structure is stabilized by intermolecular C—H⋯O hydrogen bonds and C—H⋯π interactions.
