Mineralomimetic chemistry of cyanometallates

Abstract

The structural similarity between Cdx(CN)y and SixOy in the AxBy composition, A taking tetrahedral positions linked successively with B to build up multi-dimensional structures such as 1D-chains, 2D-layers, or 3D-lattices, can be utilized in developing mineral-like but unprecedented inclusion or supramolecular structures using cadmium cyanide and cyanocadmate moieties as building blocks. Examples have been demonstrated with single crystal structures for such inclusion structures as silica-mimetic Cd(CN)₂ host clathrates, clay-mimetic 2D-layer and zeolite-mimetic 3D-lattice cyanocadmate host inclusion compounds.
