Formation of complexes of structurally comparable six silicon, boron and phosphorous Triton-X podands (Tr-podands) and silver (I) cations in propylene carbonate has been studied by the potentiometric and AM1d semi-empirical methods. Three types of these podands (2-7) form stable complexes with Ag+ cations. The stability constants of the complexes including different number of silver (I) cations are determined. It has been shown that the number of Ag+ cations complexed by the podands depends strongly on the number of oxaalkyl chains and on the type of central podand's atom (Si, B or P). The (7) podand (with six polyoxaalkyl chains) can complex as many as six silver(I) cations. The structures of these complexes are visualized by the AM1d semiempirical method
