New insight into the pectolite – serandite series: a single crystal diffraction study of Na(Ca1.73Mn0.27)[HSi3O9] at 293 and 100 K (original) (raw)

This research examines the crystal structure of the pectolite-serandite series, focusing on Na(Ca1.73Mn0.27)[HSi3O9] at two temperatures, 293 K and 100 K. The study highlights key structural features, including the distribution of Ca and Mn cations, the significance of strong hydrogen bonding in the [HSi3O9] unit, and proposes a new crystal chemical interpretation of these structures through comparisons with similar silicate frameworks. Data from single crystal diffraction and analysis of specific distances and angles provide insight into the unique characteristics of manganoan pectolite.
