Complexes of podand-containing bis(dithiophosphonate) ligands with cobalt(II), nickel(II) and cadmium(II): Recognition of CH2Cl 2

Abstract

Reaction of the potassium salts of podand-containing bis(dithiophosphonate) s [PhO(4-C6H4)P(S)(SH)OCH2CH2] 2O (H 2 L) with Co(II), Ni(II) and Cd(II) in aqueous EtOH leads to complexes of formulae M2(L-S,S')2. The structural formulae of the compounds were deduced by physico-chemical and spectroscopic methods. It was established that complex Ni 2 L 2 recognizes CH2Cl2. © 2008 Springer Science+Business Media B.V
