Abstract
Crystals of the title compound belong to space groupP¯1, withZ=1. TheK + ions and the acidic protons occupy centers of symmetry. This and the very short O⋯O distance of 2.430 (9) Å classify the compound as a typeA acid salt. The infrared spectrum shows the υ s OHO band near 800 cm−1 with remarkably good definition at −170°C.
