Abstract

In the title compound, [Zn(C10H5O4)2(H2O)2], the ZnII 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-carb­oxy­late ligands in the equatorial plane, forming a slightly distorted octa­hedral coordination geometry. O—H⋯O hydrogen-bonding inter­actions involving the water mol­ecules form infinite chains parallel to [010]
