Bridge-splitting of trans-[PtCl2(eta(2)-CH2=CH2)](2), 1, by L in dichloromethane yields trans-[PtCl2(eta(2)-CH2=CH2)(L)] (L = THF, 2, or MeCN, 3) with bridge-splitting equilibrium constants of 0.0289 +/- 0.0007 and 3601 +/- 215 mol(-1) dm(3), respectively, as determined by UV/Vis measurements. The reaction of 3 in MeCN with Cl- is essentially quantitative. The crystal structure of trans-[PtCl2(eta(2)-CH2=CH2)(CH3CN)]
