Double-walled pyr topology networks from a novel fluoride-bridged heptanuclear metal cluster

Abstract

Two isostructural metal-organic materials, <b>Tripp-1-M</b> (<b>Tripp</b> = 2,4,6-tris(4-pyridyl)pyridine; M = Co, Ni), that exhibit binodal 3,6-connected <b>pyr</b> network topology have been prepared and characterized. <b>Tripp-1-M</b> are based upon a novel M₇F₁₂²⁺ cluster that possesses 12 connection points but, because of double cross-linking by 3-connected <b>Tripp</b> ligands, it functions as a 6-connected supermolecular building block (SBB).
