Discrete Heterotrimetallic Assemblies Based on Rod-Shaped Fe^II-Metalloligands and a Zn^II-Porphyrin/Ru^II-Metallacycle.

ABSTRACT: An efficient strategy for the preparation of heterometallic discrete porphyrin assemblies, tuned both in dimensions and number of metal centers, is described. Five rod-shaped di-pyridyl Fe^II-metalloligands, with varied length (1.5 - 3.2 nm), lateral substituents, and number of iron centers, were used to bridge two Ru^II-metallacycles, made of two coplanar Zn^II-porphyrin each. The resulting architectures consist of four Ru^II complexes, four zinc-porphyrins, and either two or four Fe^II-clathrochelate units. Earlier, geometrically similar sandwich-like architectures were based on purely organic connectors. Among other novel characteristics, the use of metalloligands was found to be beneficial for the overall stability, thus allowing for a
