✦ Synopsis
Crystals of decacalcium potassium heptakis(orthophosphate), Ca 10 K(PO 4 ) 7 , were obtained from a melt. The structure of Ca 10 K(PO 4 ) 7 is isostructural with -Ca 3 (PO 4 ) 2 and has been determined previously [Morozov, Presnyakov, Belik, Khasanov & Lazoryak (2000). Crystallogr. Rep. 45,[19][20][21][22][23][24][25][26]. The present investigation confirms the previous study, but with higher precision and with all displacement parameters refined anisotropically. The structure contains four Ca, one K, three P and ten unique O atoms, of which the K, one Ca, one P and one O atom are located on threefold rotation axes.
