Abstract

The crystal structure of bis(potassium hydrogenl-malate)·malic acid, 2[K+(C4H5O5)−]·C4H6O5, has been determined: C12H16K2O15, M r =1913.9, orthorhombic, space groupP212121 a=7.719(5),b=7.916(5),c=29.863(20) Å,V c=1824.7 Å3,Z=4. The structure was determined by a new application of theDirdif procedure using MoKα automatic diffractometer X-ray data, and refined by full-matrix least squares toR=0.059 for 962 reflections. A question on space-group assignment and composition was resolved only after the structure had been determined. The conformation of the central carbon skeleton of all three crystallographic independent malate moieties isanti. The potassium ions are coordinated by eight oxygen atoms, forming face-sharing distorted square antiprisms.
