Studies of the Complexation Behavior of Tetramorpholinylo-Pnp-lariat Ether with Ag(i), Ca(ii), Cd(ii), Cu(ii) and Pb(ii) Using Electrospray Ionization Mass Spectrometry

The identification of complexes containing PNP-lariat ether with Ag(i), Ca(ii), Cu(ii), Cd(ii) and Pb(ii) by ESI-MS technique is presented. The tandem mass spectra of these complexes were done in order to evaluate the stability of the different types of the complexes formed.
