“…The IR spectrum of the microcrystalline powder at room temperature is dominated by the very strong ν (CN) vibration at 2097 cm −1 15. 18 Also the ν (CH) vibrations expected for the aliphatic and aromatic groups can be seen at 2961, 2925, and 2854 cm −1 , as well as 3047 cm −1 , respectively. The presence of the aromatic system is further proven by the ν (CC) vibrations at 1639 cm −1 .…”

“…In principle, most of the bands seen in the IR spectrum can be seen in the Raman spectrum as well. The band at 762 cm −1 is assigned to the ν (CS) vibration15, 18 (Figure 8). To investigate the speciation in the melt, Raman spectra were measured at 10 and 100 °C by using a μ‐Raman setup with excitation wavelengths of 488 and 785 nm (Figure 9 and Figure 10, respectively).…”

The compound (C4C1py)[Cu(SCN)2], (C4C1py = 1-Butyl-4-methyl-pyridinium), which can be obtained from CuSCN and the ionic liquid (C4C1py)(SCN), turns out to be a new organic-inorganic hybrid material as it qualifies both, as a coordination polymer and an ionic liquid. It features linked [Cu(SCN)2](-) units, in which the thiocyanates bridge the copper ions in a μ1,3-fashion. The resulting one-dimensional chains run along the a axis, separated by the C4C1py counterions. Powder X-ray diffraction not only confirms the single-crystal X-ray structure solution but proves the reformation of the coordination polymer from an isotropic melt. However, the materials shows a complex thermal behavior often encountered for ionic liquids such as a strong tendency to form a supercooled melt. At a relatively high cooling rate, glass formation is observed. When heating this melt in differential scanning calorimetry (DSC) and temperature-dependent polarizing optical microscopy (POM), investigations reveal the existence of a less thermodynamically stable crystalline polymorph. Raman measurements conducted at 10 and 100 °C point towards the formation of polyanionic chain fragments in the melt. Solid-state UV/Vis spectroscopy shows a broad absorption band around 18,870 cm(-1) (530 nm) and another strong one below 20,000 cm(-1) (<500 nm). The latter is attributed to the d(Cu(I))→π*(SCN)-MLCT (metal-to-ligand charge transfer) transition within the coordination polymer yielding an energy gap of 2.4 eV. At room temperature and upon irradiation with UV light, the material shows a weak fluorescence band at 15,870 cm(-1) (630 nm) with a quantum efficiency of 0.90(2) % and a lifetime of 131(2) ns. Upon lowering the temperature, the luminescence intensity strongly increases. Simultaneously, the band around 450 nm in the excitation spectrum decreases.

“…Other platinum-based perovskitoids are very likely feasible. 160 The first metal thiocyanate perovskitoid to have its structure determined was CsCd(NCS) 3 and it is unusual. Rather than having distinct hard and soft cations on the MN 6 and MS 6 sites, it has Cd ions on both.…”

Metal thiocyanates are some of the earliest reported molecular framework materials and adopta diverse range of structures. This review describes the structures, properties and syntheses ofthe known binary and ternary thiocyanates. It provides a categorization of their diverse structures,and connects them to the structures of atomic inorganic materials. In addition to this description ofcharacterized binary and ternary thiocyanates, the review summarizes the state of knowledge forall other binary metal thiocyanates. The review concludes by highlighting opportunities for futurematerials development.
