3-Methylpyridazine (3-Mepydz) reacts with halogenotrimethylplatinum(IV), [PtXMe3)4], to afford complexes of type fac-[PtXMe3(3-Mepydz)2] (X = Cl, Br or I). In solution these complexes undergo 1,2-metallotropic shifts between the contiguous nitrogen donors producing different linkage isomers. Solution abundances of these ismers are strongly influenced by the steric effects of the 3-methyl group on the pyridazine ring, with the (1,1)-isomer always being predominant (≈ 95%). Activation energies for the fluxion were determined by variable temperature 1H NMR spectroscopy, values of the (1,1) → (1,2) isomer shift being in the range 74–78 kJ mol−1.
