在25.0±0.1 ℃, 0.1 mol*L-3 NaClO4的条件下, 用pH电位滴定法测定了配体2,9-二甲基-1,10-菲罗啉的α-氨甲基吡啶衍生物-N,N′-二-α-吡啶甲基-1,10-菲罗啉-2,9-二甲胺(L)在水溶液中分别与稀土离子Ln(Ln=La3+, Ce3+, Pr3+, Nd3+, Sm3+, Eu3+, Gd3+, Tb3+, Dy3+, Ho3+)的二元配合物的稳定常数. 提出了配合物在溶液中的可能结构. 对金属离子对配合物稳定性的影响进行了详细的讨论, 并比较讨论了稀土离子和其它金属离子如Co2+, Ni2+, Cu2+等与配体L的所形成配合物的稳定性差异的原因. 运用线性回归, 对有放射性的Pm3+与相应配体的二元配合物的稳定常数进行了推测.
