Solid state structures and properties of free-base 5,10,15-triphenylcorrole (TPCor) anions obtained by deprotonation and reduction. Effective magnetic coupling of spins in (Cp 2 Cr + )(H + )(H 2 TPCor˙ 2- )·C 6 H 4 Cl 2

The reduction of 5,10,15-triphenylcorrole (H TPCor) with decamethylchromocene yields (Cp* Cr )(H )(H TPCor˙ )·C H Cl (1). It is accompanied by the deprotonation of H TPCor and the formation of planar H TPCor˙ radical dianions. Complex 1 manifests a band at about 750 nm observed in the solution spectra of H TArylCor˙ and demonstrates an EPR signal attributed to the reduced corrole macrocycle. The magnetic moment of 1 of 4.10μ at 300 K indicates the contribution of Cp* Cr (S = 3/2) and H TPCor˙ (S = 1/2). These paramagnetic species alternate in the π-stacks providing rather effective antiferromagnetic coupling of spins at the Weiss temperature of -31 K. To distinguish the H TPC˙ dianions from the deprotonated H TPCor anions, we also studied the {cryptand[2,2,2](Na )}(H TPCor )·0.5C H Cl (2) salt with deprotonated corrole anions. In this case, a planar macrocycle was formed as well. However, the properties of H TPCor in 2 differ from those of H TPCor˙ in 1.
