Perchlorato(tetraphenylporphinato)manganese(III) (TPPMnClO4) is shown to be a useful reagent for the determination of a variety of anions in nonaqueous media.The analysis is based on the displacement of coordinated perchlorate by more strongly coordinating anions as monitored spectrophotometrically.The procedure is demonstrated for the determination of tetra-alkylammonium salts of nitrate, nitrite, chloride, bromide, iodide, acetate, trifluoroacetate, cyanate, and thiocyanate in acetonitrile.Relative precisions and accuracies of the order of five parts per thousand are indicated.Key words: perchlorato(tetraphenylporphinato)manganese(III), spectrophotometric determination of anions, anions in nonaqueous media.
