Abstract: In the title compound, [Mn₃(C₈H₁₀O₄)₃(C₁₈H₁₀N₄)₂], one Mn atom and one cyclohexane-1,4-dicarboxylate (chdc) ligand are located on centres of inversion. One of the two independent Mn atoms is seven-coordinate, binding to five carboxylate O atoms from different chdc ligands and two phenanthrene N atoms from a dipyrido[3,2-a:2',3'-c]phenazine (L) ligand, while the second Mn atom is six-coordinate, binding to six carboxylate O atoms from different chdc ligands. The cis-chdc ligands bridge the trinuclear Mn^II clusters, forming chains, which are further linked into a three-dimensional network.
