Abstract: In the title compound, {[Mn(C₄H₄O₆)(H₂O)]·H₂O}_n, the Mn²⁺ ion is connected to three different tartrate anions and a water molecule, resulting in a distorted MnO₆ octahedral geometry. There are two tartrate half-anions in the asymmetric unit, both of which are completed by crystallographic twofold rotation symmetry. The tartrate dianions bridge the Mn²⁺ ions to form a wave-like infinite layer. A series of O-HO hydrogen bonds link the layers into a three-dimensional network.
