Popis:	An experiment for an integrated physical/inorganic laboratory course involving a sequence of reactions starting with the iridium(I) complex [Ir(COD)Cl]2, COD = 1,5-cyclooctadiene, is presented. The crux of the experiment is the reaction of [Ir(COD)(Ph3P)2]BF4 with dihydrogen in a valve NMR tube in the absence of dioxygen and the determination of the coordination mode of dihydrogen, η2-H2 or dihydride, by a NMR T2 relaxation measurement.
