The isomerisation of ttt-RuCl2(RNC)2 (PPh3)2 (R=2,6-xylyl, tBu, iPr, benzyl, 2-OMe-4-Clphenyl) to cct -RuCl2 (RNC)2(PPh3)2 has been carried out in the solid state. The reaction is first order and kinetic measurements have yielded activation energies of 210 kJ mol-1 (R=tBu) and 221 kJ mol-1 (R=benzyl) for reactions performed between 160 and 180 °C. XRD analysis of the solid state reaction of ttt -RuCl2 (tBuNC)2(PPh3)2 has revealed that the cct-isomer produced is a polymorph of that produced by recrystallisation of the pure cct-RuCl2(tBuNC) 2(PPh3)2 isomer. A possible mechanism for the isomerisation reaction involving rotation of the two small groups (Cl, RNC) is proposed.
