Lattice parameters of Ba7F12Cl2 for different synthesis procedures (s.u. values are typically about 0.001 Å). High-temperature and gel-growth data are taken from Kubel et al. (1999a,b), hydrothermal data from Kubel (2005), and powder diffraction data from Es-Sakhi et al. (1998) and Kubel (2005). The asterisk represents the present data. |
