Diorganodiphosphates (POP 2-) and a triorgano-methylenediphosphonate (PCP -) have been combined with zinc salts and the tridentate ligands L [L = bis(benzimidazolylmethyl)amine, bis(2-pyridylmethyl)amine, triazacyclononane, trimethyltriazacyclononane, and (dimethylaminoethyl)(2-pyridylmethyl)amine].
The new potentially threefold-chelating ligand tris[2-(1methyl-4-tolylimidazolyl)]phosphane (Pim Me,pTol ) has been prepared. The p-tolyl substituents on the imidazole rings form a shielded hydrophobic cavity. The first X-ray-structure analysis of this ligand system confirms the proposed structure.
