Descripción
Sumario:In the title compound, [Mn(C(10)H(5)O(4))(2)(H(2)O)(2)], the Mn(II) 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) Å. 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.
