Vibrational spectra and structure of cadmium(II) thiocyanate

Infrared and Raman spectral data (4000-50 cm-1) of cadmium(II) thiocyanate are consistent with a polymeric structure having a centro-symmetric octahedral coordination polyhedron around cadmium.

Barium Thiocyanate Trihydrate

Ba(SCN)2*3H2O, Mr = 307.55, is monoclinic, C2/m, with a = 15.981(1), b = 4.441(1), c = 13.333(1) Angstroem, β = 104.65(1)o, V = 915.5 Angstroem3, Z = 4, Dc = 2.23 Mg m-3, μ(Mo Kα) = 4.74 mm-1.The salt, which was reported in a previous structural study as a dihydrate , is actually a trihydrate.The third water molecule has been located and the structure has been refined to R = 0.032 for 1059 observed reflections.Ba has a tricapped trigonal prismatic coordination: four N, four O and one S (Ba-N = 2.90-2.91, Ba-O = 2.71-2.90, Ba-S = 3.39 Angstroem).Bond lengths within the two independent thiocyanate groups are N-C = 1.15 and C-S = 1.65-1.66 Angstroem.The water molecules are involved in O-H...S hydrogen bonds with O...S = 3.36-3.77 Angstroem.E.s.d.'s for distances involving nonhydrogen atoms are A reversible phase transition was found to occur at about 135 K by Raman spectroscopy.

Photoluminescence of Ba(SCN)2:Eu2+

The luminescence properties of Eu2+ in the novel host lattice Ba(SCN)2 has been investigated. At low temperature a strong green emission is observed with a maximum at 511nm, which is strongly quenched with increasing temperatures. The excitation spectrum yielded a Stokes shift which clearly shows the presence of a 5d → 4f emission. The quenching behaviour can be explained by the fact that the lowest 5d state is located at slightly lower energy than the conduction band of the host lattice. At increasing temperature thermal occupation of the conduction band occurs followed by nonradiatively excitonic relaxation to the ground state. The luminescence properties of Ba(SCN)2:Eu2+ are very similar to those of Sr(SCN)2:Eu2+.

M(SCN)2 (M = Eu, Sr, Ba): Crystal structure, thermal behaviour, vibrational spectroscopy

Single crystals of M(SCN)2 (M = Eu, Sr, Ba) have been obtained via metathesis of NaSCN and MCl2 (M = Eu, Sr, Ba) at 340°C. The isotypic crystal structures of the thiocyanates M(SCN)2 (C2/c, Z = 4, Eu: a = 979.3(2), b = 660.8(1), c = 815.7(2) pm, β = 91.58(3)°, Rall = 0.0245, Sr: a = 985.5(2), b = 662.9(2), c = 819.6(2) pm, β = 91.29(3)°, Rall = 0.0435, Ba: a = 1018.8(2), b = 687.2(1), c = 852.2(1) pm, β = 92.43(2)°, Rall = 0.0392) contain alternating layers of M2+ and SCN-. According to M(SCN)4/4(NCS)4/4 M2+ is eight-coordinated by four sulfur and four nitrogen atoms forming a square antiprism. Thermal investigations show that the compounds melt without decomposition. Vibrational spectroscopic investigations are presented and discussed. WILEY-VCH Verlag GmbH, 2001.
