Abstract:
This study presents the first crystal structure determination of natural MgCO3·5H2O, mineral lansfordite, in comparison with previous structural works performed on synthetic analogues. A new prototype single-crystal X-ray diffractometer allowed us to measure an extremely small crystal (i.e. 0.020×0.010×0.005 mm) and refine anisotropically all non-hydrogen atoms in the structure and provide a robust hydrogen bond asset. Our new data confirm that natural lansfordite can be stable for several months at room temperature and this is in contrast with previous works, which reported that such mineral could be stable only below 10 °C.
