The asymmetric unit of the title compound, [Ni(C32H36N4)], contains two independent molecules exhibiting an overall ruffled conformation of the porphyrin macrocycle and differing mainly in the positions of the methyl groups. The average Ni-N bond lengths are 1.912 (2) and 1.910 (2) Å in the two molecules. The molecules form a closely spaced lattice structure in which neighbouring porphyrins are oriented in a nearly perpendicular fashion to each other. The compound was prepared via nucleophilic substitution of (5,15-diisobutylporphyrinato)nickel(II) with n-butyllithium.

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—Hπ interactions into supramolecular 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.
