degrees of distortion and variable M–N bond lengths dependent not only on the transinfluence of P but also on stericeffects within the complex. pH-induced chelate ring-opening of cis-[Pt(Me2N(CH2)2PPh2-P,N)2]Cl2 had an associated pK value of 6.9. In contrast, complexes with R1 and R2 = H, n = 2 or 3 or R1 = H and R2 = Me, n = 2, are more difficult to ring-open. Thus the complexes cis-[Pt(Me(H)N(CH2)2PPh2-P
