Metal−Organic Polyhedron Based on a Cu^II Paddle-Wheel Secondary Building Unit at the Truncated Octahedron Corners

Abstract

A metal-organic polyhedron of truncated octahedral geometry augmented with a C(4)-symmetric square-planar Cu(II) paddle-wheel node as a secondary building unit can be prepared using a C(3)-symmetric ligand that occupies the face of the octahedral cage, where the three phenyl groups containing a m-carboxylate group in the ligand provide the necessary curvature to form the finite octahedral cage.
