Solutions containing nucleosides: cytidine and guanosine, and Pd(II) ion in dimethylsulphoxide have been investigated using 1H NMR method. It has been found that the glycylglycinate-palladium(II) complex reacts with cytidine through its N(3) nitrogen atom as the fourth donor for Pd(II) ion, and with guanosine which binds with Pd(II) through N(7) of purine ring. The primary binding site of cytidine-guanosine pair for the glycylglycinate-Pd(II) complex was N(7) of guanosine. However, in the reaction of PdCl2 with the cytidine-guanosine pair, equivalent binding sites were N(1) of guanosine and N(3) of cytidine giving CydN(3)-Pd-N(1)Guo ternary complex.
已使用¹H NMR方法研究了在二甲基亚砜中含有核苷（胞苷和鸟苷）以及钯（II）离子的溶液。已发现甘氨酰甘氨酸 - 钯（II）配合物通过其N(3)氮原子作为钯（II）离子的第四个供体与胞苷反应，并与通过嘌呤环的N(7)与钯（II）结合的鸟苷反应。甘氨酰甘氨酸 - 钯（II）配合物的胞苷 - 鸟苷对的主要结合位点是鸟苷的N(7)。然而，在PdCl₂与胞苷 - 鸟苷对的反应中，等效的结合位点是鸟苷的N(1)和胞苷的N(3)，形成CydN(3)-Pd-N(1)Guo三元配合物。
