Formation of Hexagonal Coordination Complexes (Eur. J. Inorg. Chem. 1/2005)

Abstract

AbstractThe cover picture shows the hexagonal 2:4 coordination complex formed between 1,3‐bis(3′‐pyridylethynyl)benzene and copper(II) acetate. The ligand, synthesized by the Sonagashira coupling of 1,3‐ethynylbenzene with 3‐bromopyridine, was designed to form hexagonal coordination complexes with metals that favor linear coordination geometry. In this example the dimeric copper(II) acetate paddlewheel forms an almost linear connection between a pair of dipyridyl ligands. Details are discussed in the Short Communication by E. Bosch et al. on p. 45 ff.
