Abstract

The crystal structure of natural eakerite [Kossiakoff & Leavens (1976). Am. Mineral. 61, 956-962] has been reinvestigated, the H-atom positions determined and the hydrogen-bonding scheme elucidated. The O⋯O separations of the O-H⋯O hydrogen bonds correlate well with the frequencies of the three corresponding Raman peaks according to Libowtzky's regression curve. The Sn atom has site symmetry 1̄.
