Case Study

Ion dynamics of cesium thiocyanate

Furukawa, Yoshihiro. Journal of molecular structure 345 (1995): 119-122.

The spin-lattice relaxation time T1 or 133Cs and 14N NMR in solid cesium thiocyanate (CsSCN) is measured as a function of temperature. The 133Cs T1 in the room temperature phase (470 K > T) is minimum around 445 K when measured at a low resonance frequency of 7.95 MHz and is explained by a 180° flip of the linear SCN- ions. In the high temperature ion-plastic phase, the decrease of 133Cs T1 with temperature is attributed to the slow translational diffusion of cations and the increase of 14N T1 is attributed to the fast overall reorientation of SCN- ions.
Cesium thiocyanate was placed in a glass ampoule, the powder sample was partially melted to increase the filling factor and sealed with N2 gas. The 133Cs and 14N NMR spectra were recorded with a pulsed NMR spectrometer. The resonance frequency of 133Cs nuclei is about 35.58 MHz or 7.95 MHz, and that of 14N nuclei is about 19.60 MHz. The solid echo or free induction decay signal is averaged over 8-256 and Fourier transformed. The spin-lattice relaxation time T1 is measured by the usual 180°-90° pulse sequence.

Structural study of Neptunium complexes synthesized with cesium thiocyanate

Charushnikova, I. A., et al. Radiochemistry 57 (2015): 459-467.

The structural and spectroscopic properties of the thiocyanate complex Cs4[NpO2(NCS)5]·2.5H2O synthesized using cesium thiocyanate were studied. In the structure of Cs4[NpO2(NCS)5]·2.5H2O, the coordination circumference of the Np atom is a pentagonal bipyramidal structure, whose equatorial plane is composed of five independent nitrogen atoms of NCS-ions. There are also four independent Cs cations in the structure, and their coordination circumference is composed of O, N, C and S atoms.
The synthesis of Cs4[NpO2(NCS)5]·2.5H2O was carried out as follows. ~0.1 M NpO2Cl aqueous solution was added to the cesium thiocyanate solution, and then the solution was prepared by adding ~0.1 M HNCS solution (obtained by cation exchange with KU-23 cation exchange resin) to ~1 M Cs solution to pH ~5-6. The An: CsNCS molar ratio was greater than ~1: 10. The solution was evaporated at room temperature to produce a reaction mixture containing green-blue crystals, which were separated from the reaction mixture and subjected to X-ray diffraction analysis.

Luminescence of CsSCN doped with cesium thiocyanate

Danja, Bertha Abdu, and Njinga Ngaitad Stanislaus. IOSR J App Chem (IOSR-JAC) 4.4 (2013): 47-50.

CsSCN (CsSCN) was investigated as a suitable host lattice in luminescence. CsSCN was doped with EU2+ and the luminescence of the doped compound was measured. CsSCN was prepared from Cd(SCN) and Ca(CO). The prepared CsSCN was then doped with 0.05% EUat 220. The luminescence spectrum of CsSCN:EU2+ was measured using a diffractometer. The emission spectrum obtained was broad. The spectrum obtained was consistent with the typical spectrum of thiocyanate doped with EU2+. Therefore, CsSCN can be used as a host lattice.
The melting point of cesium thiocyanate is 207℃, so CsSCN was doped using the melt method with 0.05% Eu2+ at a temperature of 220℃. CsSCN was mixed with 0.05% Eu 2+ and then placed in an oven and the oven was slowly heated to reach the doping temperature. The doping temperature is maintained for one day to allow doping to be incorporated into the host lattice.

Cesium thiocyanate for NMR and conductivity studies to investigate ion binding

Khazaeli, Sadegh, Alexander I. Popov, and James L. Dye. The Journal of Physical Chemistry 86.21 (1982): 4238-4244.

The ion-ion and ion-solvent interactions of cesium salts in methylamine solutions were investigated by cesium thiocyanate as well as cesium-133 NMR and conductivity measurements. The concentration and temperature dependence of the 133Cs chemical shift of cesium salts in methylamine were fitted by models involving ion pairs and triions. The average formation constant Kip for ion pairs was calculated from the NMR data. The Kip value for CsI in the conductivity measurements depends on the conductivity equation used. The Onsager limiting law gives the best fit.
Cesium thiocyanate was recrystallized from reagent grade methanol and dried under vacuum at 50°C. For cesium thiocyanate solutions, the chemical shifts were independent of concentration at every temperature within the concentration range studied. To compare the results for the various salts, the concentration dependence at 25°C was plotted. The chemical shifts for cesium bromide, cesium perchlorate, and cesium nitrate could only be studied at saturation due to the low solubility of these salts in methylamine.
