Abstract—Composition and stability of triglycine complexes with Cu(II) ions in a wide range of concentration ratios at T = 298.15 K and I = 0.2 (KNO₃) have been determined by potentiometric method. Existence of CuHL²⁺, CuH${{{\text{L}}}_{{{{2}^{ + }}}}}$, CuH₂${\text{L}}_{2}^{{2 + }}$, CuL⁺, CuH_–1L, CuH_–2L^–, CuH_–3L^2–, CuL₂, CuH_–1${\text{L}}_{2}^{ - }$, and CuH_–2${\text{L}}_{2}^{{2 - }}$ species has been established.
