Charoite, as an example of a structure with natural nanotubes

Charoite from the Murun massif in Yakutiya, Russia (Vorob'ev 2008) was investigated using automated electron diffraction tomography (ADT) (Kolb et al. 2007, 2008; Mugnaioli et al. 2010) and precession electron diffraction (PED) (Mugnaioli et al. 2010, 2009), which allowed to determine the struc...

Description
Summary:Charoite from the Murun massif in Yakutiya, Russia (Vorob'ev 2008) was investigated using automated electron diffraction tomography (ADT) (Kolb et al. 2007, 2008; Mugnaioli et al. 2010) and precession electron diffraction (PED) (Mugnaioli et al. 2010, 2009), which allowed to determine the structure of charoite for the first time. The structure was solved ab initio in space group P21/m by direct methods using a fully kinematic approach. The least squares refinements with 2878 reflections F(hkl) >4sF converged to unweighted/weighted residuals R1/wR2 • 0.173/0.21 (Rozhdestvenskaya et al. 2010). © 2012 Springer-Verlag Berlin Heidelberg.
