Abstract
The formation of calcium complexes with four 2-oxo sigma(4) lambda(5) dioxazaphosphocanes has been investigated by means of IR and P-31 NMR spectroscopy. The stoichiometry of these complexes shows that two hete rocycles moieties containing each an amide and a phosphoryl group are needed to complex one Ca++ ion.
