Abstract

The crystal structure of Gysinite has been determined at the composition La0.16Nd1.18Pb0.66(CO3)2(OH)1.34 · 0.66 H2O, Mr = 483.85. Orthorhombic space group Pmcn, a = 5.0028(8), b = 8.555(1) and c = 7.2392(8) Å, V = 309.83 Å3, Z = 2, Dx = 5.18 g · cm−3. Single crystal X-ray refinement, Mo, λ = 0.7107 Å, μ = 34.8 mm−1, F(000) = 425.4, room temperature, R = 0.065 for 368 independent contributing reflections. The Pb-containing Gysinite is isostructural to the Ca and Sr analog Ancylite and to synthetic hydroxy-carbonates of lanthanides elements.
