X-ray structure determinations of Langbeinite type K2(Cda-xCox)2(SO4)3, x = 0.02 at three temperatures (440, 540 and 640 K) above the P213-P212121 transition temperature (434 K) reveal that the M 2+ (M2+=Cd) ion is displaced from the centre of the octahedron at all temperatures in the cubic phase. S
