P-Stereogenic 18-diphosphacrown-6 derivatives containing a chiral bisphosphine unit were synthesized. This is the first practical method for the synthesis of optically pure diphosphacrowns. The diphosphacrowns have the structure of a chiral figure "8" with chiral heteroatoms that interact directly with guest ions and molecules. Pd(II) and Pt(II) complexes with the P-stereogenic diphosphacrowns were also synthesized and characterized.
