- Abstract
Crystals of three new synthetic double salt compounds were obtained in the course of research on kröhnkite-type and natrochalcite-type materials. The crystal structures of the two sulfates: K2Cd3(SO4)4·5H2O, (space group P21/c, Z = 4, a = 19.499(3), b = 9.780(1), c = 9.899(2) Å, β = 101.17(1)°, V = 1852.0(8) Å3); Rb2Cu3(SO4)3(OH)2 (space group Pnma, Z = 4, a = 14.571(3), b = 18.230(4), c = 4.949(1) Å, V = 1314.6(5) Å3) and of the selenate Cs2Cu(SeO4)2·4H2O (space group P21/n, Z = 2, a = 7.427(1), b = 7.878(1), c = 11.743(2) Å, β = 106.31(1)°, V = 659.4(2) Å3) have been determined by single-crystal X-ray diffraction. The data were collected with a CCD area detector at 293 K for the two sulphates and at 110 K for the selenate, and were refined to R(F) = 0.033, 0.025 and 0.036, respectively. © 2002 Elsevier Science B.V.
