Yttrium thiocyanate-based supramolecular architectures: Synthesis, crystal structures, and thermal properties

Europium and terbium thiocyanates: Syntheses, crystal structures, luminescence and magnetic properties

“…The complex compounds [M(H 2 O) 5 (NCS) 3 ]ÁH 2 O (M(III) = Eu, Tb) that we synthesized are isostructural to the yttrium analogue [10]. In all the three compounds, the coordination sphere of the complex-forming agent consists of 3 acid ligands and 5 water molecules (CN 8).…”

“…The thermal behavior of the compounds was studied by differential scanning calorimetry (DSC) and thermogravimetry (TG) on NETZSCH DSC 204 F1 and NETZSCH TG 209 F1 instruments, respectively [10].…”

“…The new structures were determined using a combination of the direct method and Fourier syntheses. The starting models for isostructural compounds were taken from [10]. The population values of disordered positions were obtained by isotropic refining of the structures with fixed thermal parameters of the disordered atoms (U iso = 0.08 Å 2 ) and were not refined in subsequent calculations.…”

“…4). In addition, we studied the solid-phase thermolysis of [Y(NCS) 3 (H 2 O) 5 ]ÁH 2 O in an inert atmosphere (the previous studies for this compound were carried out in an oxidative atmosphere [10]). It is clearly seen in Fig.…”

Discrete [Yb(NCS)3(H2O)5] Molecules in Pentaaquatriisothiocyanatoytterbium(III) Monohydrate

“…Among other thiocyanato complexes Ilyukhin et al finally succeeded in crystallizing [Y(NCS) 3 (H 2 O) 5 ] · H 2 O in 2011, which can be used as a structure model for the corresponding lanthanoid(III) thiocyanate hydrates. Four years later in 2015 the europium and terbium compounds were synthesized by the same group in order to investigate their luminescence and magnetic properties.…”
