title: (5,15-Dianthracen-9-yl-10,20-dihexyl-porphyrinato)nickel(II): a planar nickel(II) porphyrin.
abstract: The title compound, [Ni(C(60)H(52)N(4))], is an example of a meso tetra-substituted nickel(II) porphyrin with both meso aryl and alkyl residues. The mol-ecule exhibits a planar macrocycle with an average deviation of the 24 macrocycle atoms from their least-squares plane (Δ24) of 0.01 Å and an average Ni-N bond length of 1.960 (2) Å. The Ni(II) atom lies on a center of inversion. The structure presents a rare example for a planar nickel(II) porphyrin, as meso-substituted nickel(II) porphyrins with either only meso-aryl or with meso-alkyl residues typically exhibit a ruffled conformation.
