摘要

The K+ cation in the racemic title compound, poly[ aqua-mu 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].
