Abstract

The crystal structure of milarite (space group P6/mcc, a 10.398, c 13.771, Z = 2) from Val Giuf, Graubunden, Switzerland, was refined at 100 K from single-crystal X-ray data. Heating changed the cell dimensions to a 10.363, c 13.827 A, with the mean refr. index for this natural milarite (H (sub 2) O approx 1 wt %) decreasing from 1.542 to 1.526. Structural and IR-spectroscopic evidence indicate strong Ca-H (sub 2) O interaction but only weak hydrogen bonds in natural milarites.
