Synthesis, properties and long range 203,205Tl-13C couplings in the 13C N.M.R. spectrum of an unusual dimethylthallium(III) complex of 4,4'-Diethoxycarbonyl-3,3',5,5'-tetramethyldipyrromethene

Abstract

The title complex* has been prepared and characterized by elementary analysis, mass and 1H and 13C n.m.r, spectroscopy. Long range203,205 T1-13C couplings are observed in its 13C N.M.R. spectrum, the assignments of which are discussed.
