Planar Complexes Containing Metal‐Metal Bonds

Abstract

Abstract Planar complexes, and particularly those of platinum, can form structures containing linear chains of heavy metal atoms with metal‐metal distances as short as 3.1 Å. The bonding in these chains can be strengthened by partial oxidation, and the bond lengths can be reduced to 2.8 Å in this way. Model structures for the novel nonstoichiometric products, such as K 2 [Pt(CN) 4 ]Cl 0·32 · 2.6 H 2 O, are considered. The bonding is also discussed on the basis of a one‐dimensional band model.
