Abstract
Base hydrolysis of bis-bipyridylplatinum(II) occurs via a 1:1 intermediate adduct with hydroxide ion. The equilibrium constants for this 1:1 addition of hydroxide in water to complex ions [PtL2](2+), where L = one of the isoe lectronic set 2,2'-bipyridyl (bpy); 2,2'-bipyrazine (bpz); 3,3'-bipyridazin e (bpdz) and 2,2'-bipyrimidine (bpym) are respectively (as log(10)K at 25 d egrees C): 4.23, 4.59; 3.82; 6.14. This result is rationalized in terms of addition at the 6-position of the ligand.
