Pt（H2O）4 2+与甘氨酸（glyH）反应生成Pt（H2O）3（glyH-O）2+和Pt（H2O）2（glyH-O）2 2+，与（甲基亚氨基）二乙酸（midaH 2）反应生成Pt（H2O）3（midaH 2-O）2+。当加热时，mida络合物不产生mer-Pt（mida）（H2O），而是一种复杂的物质混合物，可能具有Pt-N-CH 2CO 2-Pt桥接。cis-Pt（NH3）2（H2O）2 2+与甘氨酸生成cis-Pt（NH3）2（glyH-O）（H2O）2+，其通过15 N、195 Pt、13 C和1H NMR表征，其仅缓慢转化为螯合物Pt（NH3）2（gly-N，O）+。与midaH 2发生类似的反应。顺式Pt（NH3）2（OH）2在碱性溶液中与甘氨酸盐缓慢反应生成顺式Pt（NH3）2（gly-N）2和顺式Pt（NH3）2（gly-N）（OH）。
Pt(H2O)4 2+ with glycine (glyH) gives Pt(H2O)3(glyH-O)2+ and Pt(H2O)2(glyH-O)2 2+ and with (methylimino)diacetic acid (midaH2) Pt(H2O)3(midaH2-O)2+. The mida complex, when heated, does not give mer-Pt(mida)(H2O) but a complex mixture of species, probably with Pt-N-CH2CO2-Pt bridging. cis-Pt(NH3)2(H2O)2 2+ with glycine gives cis-Pt(NH3)2(glyH-O)(H2O)2+, characterized by 15N, 195Pt, 13C, and 1H NMR, which only slowly converts to the chelate complex Pt(NH3)2(gly-N,O)+. Analogous reactions occur with midaH2. cis-Pt(NH3)2(OH)2 in alkaline solution reacts slowly with glycinate to give cis-Pt(NH3)2(gly-N)2 and cis-Pt(NH3)2(gly-N)(OH).
