Positions with symmetry
Wilson, A. J. C., Karen, V. L. and Mighell, A.  International Tables for Crystallography (2006). Vol. C, Section 9.7.4.2, pp. 902-903 [ doi:10.1107/97809553602060000623 ]
... by other symmetry elements. All centres of symmetry in , P21/c and Pbca are free, as are some of those in ... symmetry element, the special position can still be occupied by a molecule of symmetry only, but when the encumbrance is syntropic or atropic the position cannot accommodate such a molecule. Table 9.7.2.1 indicates that there are 38 space ...
