Open-framework coordination complexes from hydrogen-bonded networks: toward host/guest complexes

Coordination compounds with peripheral hydrogen bonding substituents have been used to assemble infinite frameworks of one, two, and three dimensions. The propagation of 1D, 2D and 3D network depends on the nature of the metal ion, the number of hydrogen bonding substituents used, and the nature and placement of the hydrogen bonding substituents. An overview of coordination complexes connected via simple hydrogen bonding substituents, e.g. carboxylic acids and carboxamides, is given, and analogous organic and inorganic hydrogen bonding networks are discussed. The use of 2D and 3D hydrogen-bonded coordination networks in creating host-guest networks is also discussed. (C) 2003 Elsevier B.V. All rights reserved.
