The Ca1 polyhedron in pascoite. Oxygen atom O13 is disordered into two half-occupied sites, O13A and O13B, and a hydrogen associated with O13B (H13B, Table 2) is also half-occupied. On either “side” of the equatorial plane defined by O10 and O11, either the O13A site or the pair of O13B sites is occupied. Thus, Ca1 can be 6-, 7-, or 8-coordinated with oxygen, with an average of Ca1O7. Hydrogen atom “x” = H13A, hydrogen atom “y” = H13B.
