Abstract
Los estudios potenciométrico, conductimétrico y espectro fotométrico, de sistemas acuosos H2L/M(II) del ácido C-benciliminodiacético [H2L = C-Bz-IDA 0CH2N(CH2C02H2] con cationes M(II) (M = Cu, Ni, Co, Zn, Cd y Pb) revelan la formación de especies MHL, ML Y ML2-2. La comparación de las constantes estequiométricas de formación (Iog B) Y en su caso de disociación ácida (pK.) de estos complejos, calculadas para 1=0.1 M (KNO3) y t = 25.00 ± 0.05 ºC, con datos de bibliografia para que latos con ligandos relacionados, permite discutir la estructura más probable de los quelatos investigados.
