Abstract | {meso-Phenyldipyrromethanes can be oxidized by 2,6-dicyano-3,5-dichloro-para-benzoquinone (DDQ) to the corresponding meso-phenyldipyrrins. As expected, these novel, stable bipyrrolic pigments readily form metal chelates with copper(II), nickel(II), and zinc(II). Their W-VIS spectra are compared with a series of blown alkyl-substituted dipyrrin chelates and, based oil the W-VIS spectral analysis, the dihedral angle between the two ligands iri the bis[meso-phenyldipyrrinato]Ni(II) complex was calculated to be 42 degrees. The molecular structure of this complex was determined by X-ray crystallography, essentially confirming the calculation. Crystals of C30H22N4Ni are orthorhombic |
