A novel two-dimensional mercury antimony telluride: Low temperature synthesis and characterization of RbHgSbTe3

RbHgSbTe3 (I), a novel two-dimensional quaternary mercury antimony telluride, was synthesized via an unconventional low-temperature route. Single crystals of I were grown at 180°C from solvothermal reactions using ethylenediamine as solvent. The crystal structure of I was determined by X-ray diffraction methods. The structure belongs to the orthorhombic crystal system, space group Cmcm (no. 63), a = 4.590 (2) A, b = 15.745 (4) A, c = 11.737 (2) A, Z = 4. The crystal structure of this compound consists of two-dimensional layers of ∞2[HgSbTe3- ] with Rb+ counterions located between the layers. Optical studies performed on the powder samples of I suggested that the compound is a narrow-gap semiconductor. A band-gap of 0.2 e V was estimated from its diffuse reflectance spectrum.

Mixed valent ternary iron chalcogenides: AFe2X3 (A = Rb, Cs; X = Se, Te)

The isostructural compounds RbFe2Se3, RbFe2Te3, CsFe2Se3 and CsFe2Te3 were obtained as coarse lustrous crystals by reacting Fe, Se or Te and the corresponding alkali monochalcogenide. They are orthorhombic, oC24, space group Cmcm, Z = 4, with a = 9.507(3) A, b = 11.583(4) A, c = 5.638(2) A (RbFe2Se3); a = 10.126(9) A, b = 12.486(7) A, c = 5.921(1) A (RbFe2Te3); a = 9.834(5) A, b = 11.828(6) A, c = 5.673(2) A (CsFe2Se3); a = 10.438(4) A, b = 12.501(6) A, c = 5.958(2) A (CsFe2Te3). The crystal structures of RbFe2Se3, RbFe2Te3 and CsFe2Se3 were determined by single crystal diffractometer data and refined to conventional R-values of 0.043, 0.042 and 0.082 respectively. Isotypy of CsFe2Te3 was established from its powder diagram. The title compounds are isostructural with rasvumite, KFe2S3. Their crystal structures are characterized by infinite double chains of edge-sharing iron-centred chalcogen tetrahedra running parallel to [001]. The mean Fe-Se bond lengths are close to 2.39 A, the mean Fe-Te bond length in RbFe2Te3 is 2.57 A. The shortest Fe-Fe distances range from 2.765(5) A in the selenides to 2.821(4) A in RbFe2Te3.

The synthesis and crystal structure of K2UTe3

Syntheses of K2UTe3 were performed via polytelluride fluxes from K2Te3 and metallic uranium in the molar ratio 2:1 at 600 to 800 °C. Well-formed crystals were isolated by washing the reguli with liquid ammonia. One-phase powder samples of K2UTe3 are also available by reactions of stoichiometric mixtures of K2Te3 and uranium. K2Te3 was prepared in liquid ammonia from the elements using a glass apparatus specially designed for the synthesis of alkali metal chalcogenides. By x-ray structure analyses of single crystals we found K2UTe3 to crystallize monoclinic (space group C2/m, Z = 4) with the lattice parameters a = 800.41(3) pm, b = 1387.67(5) pm, c = 851.63(4) pm and β = 108.495(3)°. The crystal structure of the compound may be regarded as a stuffed AlCl3-type structure. The existence of an analogous compound Rb2UTe3 crystallizing isotypically to K2UTe3 has been shown by x-ray powder investigations.

Complex chalcogenides of the IVa metals with low dimensional anionic partial structures. Preparation and crystal structures of K2ZrTe3 and Rb2ZrTe3

The isostructural compounds K2ZrTe3 and Rb2ZrTe3 were obtained at 1000°C by reacting K2Te and Rb2Te with stoichiometric amounts of Zr and Te. The compounds are monoclinic, mP24, space group P21/c, Z = 4 with a = 9.089(3), b = 14.148(4), c = 6.986(3)A, β = 105.90(1)° and a = 9.735(4), b = 14.300(7), c = 6.952(8) A, β = 108.61(2)°, respectively. The crystal structure was determined from diffractometer data and refined to R = 0.030 for 1452 Fo's for K2ZrTe3 and R = 0.038 for 1131 Fo's for Rb2ZrTe3. The crystal structure is of a new type, characterized by infinite anionic chains, 1∞ -[ZrTe3]2- built up by octahedra sharing opposite faces which run along [001]. The mean Zr-Te bond lengths are 2.921 and 2.920 A, respectively. The alkali cations separating the chains are characterized by two different - distorted octahedral and pentagonal bipyramidal - chalcogen environments.
