(5,15-Dianthracen-9-yl-10,20-dihexyl-porphyrinato)nickel(II): A planar nickel(II) porphyrin

Abstract

The title compound, [Ni(C60H52N4)], is an example of a meso tetrasubstituted nickel(II) porphyrin with both meso aryl and alkyl residues. The molecule exhibits a planar macrocycle with an average deviation of the 24 macrocycle atoms from their least-squares plane ([Delta]24) of 0.01 ? and an average Ni-N bond length of 1.960 (2) ?. The NiII 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.
