title: Potentiometric studies of binary and ternary complexes of amoxycillin.
abstract: The formation equilibria for the binary complexes of copper(II), nickel(II), cobalt(II) and zinc(II) with amoxycillin (Amx) and for the ternary complexes M(Arm)(Amx), where Arm refers to aromatic amines, namely 2,2'-dipyridyl or 1,10-phenanthroline, were investigated by a potentiometric technique. The protonation constants of amoxycillin and conditional stability constants of the formed complexes were determined at 25 degrees (=0.1M NaNO(3)). Probable mode of chelation with amoxycillin is discussed.
