摘要：

Extensive potentiometric and spectrophotometric (visible region) data resulted in the unravelling of the complete details of complex formation of N,N'-bis(2-aminoethyl) oxamide (L(1)) and N,N'-bis(3-aminopropyl) oxamide (L(2)). This study reveals both similarities and differences in complex formation for these ligands. Earlier reports gave evidence for the formation of a Cu(3)L(2)H(-4) complex of L(2). We show that L(1) forms a Cu(2)L(2)H(2), complex. This difference in behaviour is due to a decrease in stability of the CuLH(-2) complex of L(2) compared to that of L(1). The complexation of Ni2+ by L(1) is also discussed.
