Abstract: The title compound {systematic name: bis(-2,3-dimethyl-7-oxobicyclo[2.2.1]heptane-2,3-dicarboxylato)bis[(1,10-phenanthroline)manganese(II)] hexahydrate}, [Mn₂(C₁₀H₁₂O₅)₂(C₁₂H₈N₂)₂]·6H₂O, comprises centrosymmetric dinuclear neutral molecules in which two Mn^II centers are bridged by a single carboxylate group of each of two cantharidinate ligands, together with water molecules. In the complex, each Mn^II atom is in a distorted octahedral geometry, being coordinated by two N atoms of one 1,10-phenanthroline ligand, three O atoms from one cantharidinate dianion and one carboxylate O atom from another cantharidinate dianion. Adjacent molecules link to each other through hydrogen bonds involving solvent water molecules and carboxylate groups, forming a three-dimensional network.
