trans-[Co(en)2Cl2]Cl, trans-[Co(3,2,3-tet)Cl2]Cl (3,2,3-tet = 1,5,8,12-tetraazadodecane), cis-α-[Co(trien)Cl2]Cl and [Co(tren)Cl2]Cl result in the formation of [Co(en)2(ox)]Cl · 4H2O (1), cis-β-[Co(3,2,3-tet)(ox)]Cl· 4 H2O (2), cis-α-[Co(trien)(ox)]Cl · 2 H2O (3), and [Co(tren)(ox)](ClO4) · 0.5 H2O (4) respectively, implying a hydrolytic cleavage of the amide bond. [Co(tren)(O,O′-oxam)]Cl2 · 2 H2O (5)
单草酰胺钠 (H2NCOCO2Na) 与反式-[Co(en)2Cl2]Cl、反式-[Co(3,2,3-tet)Cl2]Cl (3,2,3-tet = 1,5,8) 的反应,12-四氮杂十二烷), cis-α-[Co(trien)Cl2]Cl 和 [Co(tren)Cl2]Cl 导致形成 [Co(en)2(ox)]Cl · 4H2O (1), cis -β-[Co(3,2,3-tet)(ox)]Cl·4 H2O (2)、顺-α-[Co(trien)(ox)]Cl·2 H2O (3) 和 [Co (tren)(ox)](ClO4) · 0.5 H2O (4) 分别表示酰胺键的水解裂解。[Co(tren)(O,O'-oxam)]Cl2 · 2 H2O (5) (oxam = H2NCOCO2−) 和 p-[Co(tren)(NH3)(O-oxam)]Cl2 (6) 也有制备是为了提供单草酰胺水解
