New Highly Conducting Coordination Compounds
The past 10–15 years have seen an extensive search in many laboratories for coordination complexes which exhibit high conductivity in the solid state. Indeed the chemical systems which have given us properties illuminating most clearly the basic physics of the one dimensional state have been of this type. However, until recently, physical measurements on highly conducting metal coordination compounds have concentrated on the single inorganic prototype one-dimensional (1-D) conductor K2Pt(CN)4•Br0.3• 3H2O, KCP, simply because of a scarcity of other well characterized examples. This unusual situation was, in retrospect, of great benefit. The strikingly unusual properties of KCP and related compounds have been an intellectual attraction, particularly for the physicists and the challenging problems relating to fluctuations, disorder, competing instabilities and broken symmetry have attracted many of the most distinguished solid state scientists to the field. Their contributions, although relatively abstract, have played a key role in building our present understanding of these materials. In addition the field has served to develop a variety of interdisciplinary collaborations, from which each discipline is now benefitting.
