Abstract:	New complexes of cadmium iodide with 1,3-bis[2-(diphenylphosphoryl)phenoxy]propane [CdL⁰I₂], 1,2-bis[2-(diphenylphosphorylethyl)phenoxy]ethane [CdL^{1, 2}I₂], and 1,8-bis[2-(diphenylphosphorylethyl) phenoxy]-3,6-dioxaoctane [CdL^{3, 2}I₂] are synthesized and their IR spectra and crystal structures are studied. Electroanalytical characteristics of membranes of ion-selective electrodes based on L⁰, L^{1, 2}, L^{3, 2}, and known crown ethers are compared for cations of alkali, alkaline-earth, and transition metals. Ligand L^{3, 2} is the first podand with terminal diphenylphosphoryl fragments to exhibit selectivity with respect to the cadmium cation.
