Abstract

Thermodynamically controlled platinum(II) spherical complexes were synthesized via temporary labilization of inert Pt(II)-pyridine bonds by the addition of the strong hydrogen-bond donor 2,2,2-trifluoroethanol (TFE), which weakens the pyridine-metal interaction. The platinum complex was stably trapped after removal of TFE and showed higher acid durability than its palladium counterpart.
