✦ Synopsis


The i.r. spectra (4000-80 cm-') of the newly-reported complexes cisand trans-[Pt(pzhXr] (pz = pyrazine; X = Cl, Br, I, N02) are discussed. Assignments for internal l&and modes are based on the effects of ligand deuteration. Assignments of metal-l&and modes are based on the effects of halide substitution and pyrazine labelling~

Aqueous hydrogen halides HX (X = Cl, Br, I) are shown to containing derivatives, but the only stable isomer containing iodine was trans(I)-Ru(dmbpy)(CO) 2 I 2 . The failure to obtain be excellent halogen sources for the synthesis of a series of halogen-containing ruthenium mono(2,2Ј-bipyridine) car-
