(a) One cation and (b) part of a hydroxide–water ribbon with atomic labelling (H atoms of the cation have the same numbers as the C atoms to which they are bonded and are distinguished by an additional letter). Displacement ellipsoids correspond to the 50% probability level. H atoms are represented by spheres of arbitrary radii (ORTEP-3; Farrugia, 1997). [Symmetry code: (i) −x + , y + , z + .] |
