Table 2. Results of X-ray single-crystal diffraction and electron-microprobe analysis for wagnerite and a few related minerals from different localities.
Chemical compositions are presented for M and (F, OH) positions in M 2(PO4)(F, OH), where X is mole fraction. The average ionic radii for M is calculated as r(M) (average) = X Mg(0.72)+(1X Mg)(0.78), parameters from Shannon (1976 ▶).

Crystals were mesured on an EnrafNonius (CAD4) diffractometer with a conventional point detector. The periodicity of the structures was determined using diagnostic ‘fingerprint’ reflections whose hkl indices correspond to the superstructures and not to the basic (1b) type.
The cell parameters and chemical compositions of these samples are taken from the cited papers and recalculated in terms of our settings and formula units. Data on all the other samples were obtained in the present study.
