Binary copper(II) and uranyl(VI) complexes of glycocyamine, taurine and pyridoxal and ternary complexes involving 2,2′-bipyridine, 1,10-phenanthroline or nitrilotriacetic acid

A potentiometric study of guanidinoacetic acid complexation with the ions Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Pb(II)

“…As is already known from previous studies 13 , the guanidino group is very weakly acidic (pK = 12-15). Thus coordination through its nitrogen atoms is very difficult.…”

Interaction of Taurine With Metal Ions

“…Thus taurine may 4 and mixed ligand complexes of nickel(II) with taurine, DLmethionine and DL-ethionine 5 have been carried out. However these studies were limited due to hydrolysis of the metal cation which occurred at quite low pH values.…”
