The crystal structure of ginorite, Ca 2 [B 14 O 20 (OH) 6 ]·5H 2 O, from the Chelkar salt dome, western Kazakhstan, has been refined at 150(2) and 296(2) K. The mineral is monoclinic, P 2 1 / c , unit-cell parameters are (at 150/296 K): a = 12.738(1)/12.728(1), b = 14.240(1)/14.303(1), c = 12.750(1)/12.755(1) A, β = 101.163(2)/101.147(2)°, V = 2268.9(4)/2278.3(4) A 3 , Z = 4. The crystal structure is isotypic to that of strontioginorite and is based upon 2-dimensional anionic layers with the…
