Structural Information on Supramolecular Copper(II) β-Diketonate Complexes from Atomic Force Microscopy and Analytical Ultracentrifugation.

ABSTRACT: Supramolecular Cu(II) complexes were prepared from two trifunctional β-diketone ligands. The ligands (CH₃Si(phacH)₃ and CH₃Si(phprH)₃, represented by LH₃) contain three aryl-β-diketone moieties joined by an organosilicon group. The complexes have the empirical formula Cu₃L₂, as expected for combinations of Cu²⁺ and L^3-. Several metal-organic polyhedra (MOPs) [Cu₃L₂]_n are possible (n = 1-10); a dodecahedron (Cu₃₀L₂₀; n = 10; estimated diameter of ca. 5 nm) should be the most stable because its internal bond angles would come closest to ideal values. Atomic force microscopy (AFM), performed on samples deposited from sol
