In addition to the binary metal thiocyanates outlined above, there are many more solid-state inorganic metal thiocyanates with more complex compositions. In this review I have restricted discussion to the ternary homoleptic thiocyanates, A x M y (NCS) z , as they illustrate the distinctive features of metal thiocyanate chemistry. Ternary thiocyanates can be broadly classified by the dimensionality of the coordination framework: 3D-, 2D-and 1Dconnected frameworks, and 0D salts containing only discrete metal thiocyanate complexes.
