A second C-centred monoclinic modification of racemic potassium hydrogen malate monohydrate

G.-C. Ou and S. W. Ng

Abstract: The K⁺ cation in the racemic title compound, poly[aqua-₆-malato-potassium(I)], [K(C₄H₅O₅)(H₂O)]_n, exists in an irregular eight-coordinate environment. The anions are linked through hydrogen bonds into a three-dimensional network. The coordination environment differs from the six-coordinate environment reported in another C-centred monoclinic modification [Geise, van Loock & Lenstra (1983). Acta Cryst. C39, 69-70].
