چکیده
The title compound, C(22)H(16)N(2)O(4), was obtained unintentionally as the product of an attempted synthesis of a new phthalocyanine. The dihedral angles formed by the central benzene ring with the aromatic rings of the meth-oxy-phen-oxy groups are 85.39 (5) and 64.19 (5)°.

In the title compound, C(36)H(44)N(2)O(2), the dihedral angles between the phthalonitrile ring and the two di-tert-butyl-benzene rings are 68.134 (8) and 70.637 (11)°. The two nitrile groups are almost coplanar with the phthalonitrile ring except for one of the N atoms which deviates from the plane by 0.125 (4) Å. One of the tert-butyl groups is disordered over two orientations, with refined oc...

The whole mol-ecule of the title compound, C16H18O4, is generated by twofold rotational symmetry; the twofold axis bis-ects the central C-C bond. The O-C-C-O torsion angle about the central C-C bond is 69.45 (16)°. Symmetry-related benzene rings are inclined to one another by 64.91 (8)°. In the crystal, mol-ecules are connected by C-H⋯O hydrogen bonds, forming a three-dimensional network.

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 [centr...
