Anion-encapsulating, discrete prism and extended frusta, from trimetallated triangular macrocycles and linkers

Abstract

Reaction of a trinuclear triangular macrocyclic complex Pb₃L(CF₃SO₃)₆ with bidentate linkers in a ratio of 3 equiv. of linker per 2 equiv. of complex, produces a prismatic structure with 4,4′-dipyridyl, and two unprecedented, extended 3D frustum-like structures with 1,2-di(4-pyridyl)ethylene and 1,4-di(4-pyridyl)benzene. The cavities of these structures encapsulate triflate anions.
