Abstract

original image

New phosphorus-containing donor ligands capable of coordinating to several metal atoms are derived from a calix[4]arene derivative. This ligand is a cyclic tetramer consisting of m-linked (2-R2PO-5-tBuC6H2)-CH2 units. Shown on the right is half of the centrosymmetric complex formed upon reaction of this ligand with [Cu(CO)Cl]n. Four differently bonded copper atoms are present (the ligands R are omitted).
