The site parameters of the hydrogen atoms could not be determined due to the relatively high R factors that could not be significantly reduced, even with the use of empirical absorption corrections; the clearly anisotropic O(6) atom in NaMn and the fact that the O atomic positions in NaMg could only be refined isotropically compounded the problem.
