title: Crystal structure of 5,10,15-triphenyl-20-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)porphyrin.
abstract: 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 mol-ecules are linked by C-H⋯π inter-actions into supra-molecular chains running along the a-axis direction. A pair of bifurcated N-H⋯(N,N) hydrogen bonds occur across the central region of the macrocycle.
