Abstract

Indexed X-ray powder diffraction data derived from Rietveld crystal structure refinements are reported for synthetic potassium-richterite (KRC: K[CaNa]Mg5Si8O22(OH)2), nickel-potassium-richterite (NIKRC:K[CaNa] Ni5Si8O22(OH2) and cobalt-potassium-richterite (COKRC:K[CaNa]Co5Si8O22 (OH2). The following dimensions were obtained: KRC: a = 10.0547(8), b = 17.997(1), c = 5.2746(4)Å, β = 104.832(5)°; NIKRC: a = 10.0297(7), b = 17.942(1), c = 5.2576(4)Å, β = 104.982(5)°; COKRC: a = 10.1166(9), b = 18.066(1), c = 5.2752 (4)Å, β= 104.846(6)°.
