In the title compound, [Mn(C(10)H(5)O(4))(2)(H(2)O)(2)], the MnII atom lies on a crystallographic inversion center and is six-coordinated by two O atoms from water molecules in the axial positions and four O atoms from two deprotonated coumarin-3-carboxylic acid ligands in the equatorial plane. The overall coordination geometry is slightly distorted octahedral. The Mn-O bond distances vary between 2.0931 (12) and 2.2315 (13) A. O-H...O hydrogen bonds between the H atoms of coordinated water molecules and the O atoms of the carboxylate groups link the complex molecules into two-dimensional layers parallel to the ab plane.
