چکیده
In the title compound, C(10)H(10)N(4)O(4), the two imidazole rings adopt a trans conformation and are inclined to one another at a dihedral angle of 55.64 (4)°. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯N hydrogen bonds into chains running parallel to [010] and layers are formed from these by inter-molecular C-H⋯O hydrogen bonds. Additional C-H⋯O hydrogen bonds produce a three-dimensional network.

In the crystal structure of the title compound, 2C(8)H(6)O(4)·3C(20)H(22)N(4), there are three independent 2,2'-dimethyl-1,1'-(butane-1,4-di-yl)dibenzimidazole mol-ecules, each of which lies on an inversion centre. The terephthalic acid mol-ecules are linked to adjacent 2,2'-dimethyl-1,1'-(butane-1,4-di-yl)dibenzimidazole mol-ecules via O-H⋯N hydrogen bonds.

The title compound, C(44)H(30)N(4)O(2), was prepared from 6,6'-dibromo-2,2'-dieth-oxy-1,1'-binaphthalene through a coupling reaction with 4-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)benzaldehyde followed by a Knoevenagel reaction with malononitrile. The dihedral angle between the symmetry-related naphthalene ring systems is 68.82 (8)° while the dihedral angle between the the naphthalene rin...

In the title compound, C(12)H(18)N(4)O(2), unlike other unconjugated disubstituted biimidazole derivatives reported so far, the two imidazole rings in a trans conformation exhibit a large planar rotation angle of 51.27 (4)°, and consist of half-mol-ecule asymmetric units related by a twofold rotation. The mol-ecules are linked into a three-dimensional framework with a parallel laminated constru...
