Figure 5
d(M—OH) determined by experiment for a variety of LDH phases plotted against the value calculated using ionic radii. The circles with full-line circumferences represent the data from structures that were determined using single crystals and the dotted-line circles are for structures determined using powder data. The lines are explained in the text. The data are from the following references: (1) For single crystals: Allmann (1968 , 1969 ) (pyroaurite and `sjögrenite'); Arakcheeva et al. (1996 ) (quintinite-2H-3c); Braithwaite et al. (1994 ) (iowaite); Cooper & Hawthorne (1996 ) (shigaite); Huminicki & Hawthorne (2003 ) (nikischerite); Krivovichev et al. (2010a ) (quintinite-2H-3c); Krivovichev et al. (2010b ) (quintinite-1M); Merlino & Orlandi (2001 ) (zaccagnaite); Pastor-Rodriguez & Taylor (1971 ) (coalingite); Rius & Allmann (1984 ) (wermlandite); Rius & Plana (1986 ) (motukoreaite); Zhitova et al. (2010 ) (quintinite-2H); (2) for powder where the data are used in the fit: Bellotto et al. (1996 ) (Mg–Al); Constantino et al. (1998 ) (Mg–Al); Ennadi et al. (2000 ) (Zn–Al); Lombardo et al. (2005 ) (Zn–Al–Cl); Lozano et al. (2012 ) (Zn–Al, zaccagnaite-3R); Manohara & Vishnu Kamath (2010 ) (Co–Ga, Mg–Ga); Manohara et al. (2011 ) (Mg–Fe); Mills et al. (2011 ) (Mg–Cr, barbertonite); Radha et al. (2007a ) (Zn–Al); Roussel et al. (2000 ) (Zn–Cr); Witzke & Raade (2000 ) (Zn–Al, zincwoodwardite); (3) powder data outliers: Lombardo et al. (2005 ) (Zn–Al–CO3); Manohara & Vishnu Kamath (2010 ) (Ni–Ga); Mills et al. (2011 ) (Mg–Cr, stichtite); Radha et al. (2011 ) (Zn–Al–SO3, Zn–Al–IO3); Radha et al. (2007b ) (Co–Al, Mg–Al). |
