Crystal structure of cerium (IV)-di-potassium trisulfate monohydrate
The compound K2Ce(SO4)3 x H2O (I) was obtained in a study of the system Ce(SO4)2-K2SO4-H2O4-HO2 at 50-150C (1). The refined unit-cell parameters are: a = 20.600(3), b = 7.0744 (6), c = 18.583(3) A, US = 126.083(8), V = 2189(1) AT, Z = 8, rho/sub calc/ = 3.202(2) g/cmT, space group C2. The previously given unit-cell parameters are related to those given here by the matrices 100/010/0.5 0 1 and 100/010/-1 0-1. The intensities of 3416 independent reflections (3363 with I greater than or equal to 2sigma) and the unit cell parameters were measured on a Syntex P21 four-circle automatic diffractometer (lambdaMoK , theta/2 theta scanning at variable rate from 4 to 29.3 deg/min to theta = 60). The structural calculations were done on a Nova 1200 minicomputer by means of the Syntex XTL programs and on an ES 1022 computer by means of the Struktura programs. They used the heavy atom method; the final refinement over 3240 reflections (R = 0.071) was made allowing for the anisotropy of the thermal vibrations of the atoms.
