The thermodynamic parameters for the interaction of Cu²??, Ni²??, Co²??, Cd²??, and Ag?? with the new title ligand have been determined by titration calorimetry in 50％ THF-methanol(V/V) at 25℃.Ag?? exhibited remarkably higher complexation selectivity.Ag?? and several transition metal ions have been transported using this ligand as carrier in a bulk liquid membrane. Competitive Ag??-M²?? transport studies habe also been carried out for the same system. In this membrane transport study, high transport of Ag?? was observed in both single and competitive Ag??─M²?? transport studies. The complex formation of N,N'-bis[o-(diphenylphosphino)benzylidene]ethylenediamine (P₂N₂) with silver, [Ag(P₂N₂)] (NO₃), (1) is reported. Complex 1 has been characterized by X-ray crystallography. 1 is monoclinic, space group P2₁/n (No.14), with cell dimensions α = 13.398(4) Å, b = 12.577(5) Å, c = 21.521(4) Å, β = 100.14(2) Å, V = 3570(2) ųand Z = 4.
