In the title compound, C27H29BrN4O, benzimidazole ring system and the amide moiety are planar [r.m.s. deviations = 0.016 (2) and 0.017 (1) Å, respectively]. The molecule adopts a conformation in which the amide linkage is almost perpendicular to the central ring [dihedral angle = 85.79 (8)°], while the benzimidazole ring system makes a dihedral angle of 70.26 (11)° with the central ring. In the crystal, the molecules form dimers through N—H...O hydrogen bonds and C—H...O interactions. These dimers are further linked into zigzag ribbons along [201] by weak C—H...Br interactions. As a result of the bulky nature of the molecule, as evidenced by the large dihedral angles between rings, there is little evidence for any π–π interactions.

In the title compound, C13H8ClFN2, the dihedral angle between the plane of the benzimidazole ring system (r.m.s. deviation = 0.022 Å) and the benzene ring is 26.90 (8)°. The F atom at themetaposition of the benzene ring is disordered over two sites in a 0.843 (4):0.157 (4) ratio. In the crystal, molecules are linked by N—H...N hydrogen bonds, forming infiniteC(4) chains propagating along [010]. In addition, weak C—H...π and π–π interactions [shortest centroid–centroid separation = 3.6838 (12) Å] are observed, which link the chains into a three-dimensional network.

In the title compound, C44H37BN4O2, the dihedral angle between the plane of the porphyrin macrocycle ring system [r.m.s. deviation = 0.159 (1) Å] and those of three phenyl rings are 66.11 (4), 74.75 (4) and 57.00 (4)°. The conformational distortion is characterized by a mixture of ruffled, saddle and in-plane distortion modes. In the crystal, the porphyrin molecules are linked by C—H...π interactions into supramolecular chains running along thea-axis direction. A pair of bifurcated N—H...(N,N) hydrogen bonds occur across the central region of the macrocycle.
