Most 0D metal thiocyanate structures have isolated metal centres, but there are two reported structures containing dimerized Ag(I) tetrahedra, Cs 2 [Ag(SCN) 3 ] and K 2 [Ag(SCN) 3 ], comprising edge-sharing AgS 4 tetrahedra, stabilized by intradimer argentophilic interactions (d Ag-Ag = 3.3 Å). The most diverse class of salts contain octahedrally coordinated metals, i.e. [M(NCS) x (SCN) 6-x ] y-anions, for which crystal structures exist for y from 2 to 4, and for x = 0 or 6, other values are reported with organic cations and solvates. Na 4 [Mg(NCS) 6 ] has a trigonal structure, P31c, built from two kinds of layers, the first composed of alternating [Mg(NCS) 6 ] 4 -and Na + cations and the second containing just Na + cations. Cs 3 [Mo(NCS) 6 ] is hexagonal, with columns of [Mo(NCS) 6 ] 3 -anions with Cs + cations in between. The crystal structure shows very significant disorder which remains present down to 115 K. with isolated [Rh(SCN) 6 ] 3 -anions, but the structure (due to limitations of contemporary crystallography) has no information about the SCN -ligand location. The limitations of historic crystallographic analysis unfortunately also affect K 2 [Pt(SCN) 6 ] and Rb 2 [Pt(SCN) 6 ], which are isostructural and crystallise in the space group P3m1. The thiocyanate anions cannot be resolved, but the arrangement of the alkali cations and [Pt(SCN) 6 ] 2 -anion is likely an anti-CdI 2 structure type. Next, there are four reported crystal structures with four coordinate metals, tetrahedral K 2 [Hg(SCN) 4 ] 206 and K 3 [Ag(SCN) 4 ] 202 and the square-planar isostructural K 2 (Pd(SCN) 4 ) 207 and K 2 [Pt(SCN) 4 ], both of which have weak axial M-S bonds which would connect the square planar units into chains.
