Abstract
Complex formation between N,N,N',N'-tetrakis(2-aminoethyl)ethane-1,2-diamin e (penten) and the metal ions Mn2+, Co2+, Cu2+, Zn2+, Cd2+, Hg2+, Ag+, Pb-2 , and Tl3+ (in 1.00(M) NaNO3 and 25 degrees) was investigated by potentiome try and spectrophotometry. These are the first reported values of the stabi lity constants for this ligand with Ag+, Pb2+, and Tl3+. The X-ray crystal structure of [Tl(NO3)(penten)](NO3), was determined. In this structure. Tl3 + shows a coordination number of seven made up of the six N-donors and one O-atom of NO3-.
