Bis(ethanamidinium) (1,10-phenanthroline-2,9-dicarboxylato)manganate(II) heptahydrate

In the title complex, (C2H7N2)2[Mn(C14H6N2O4)2]·7H2O, the MnII atom is coordinated by four N atoms and four O atoms from two 1,10-phenanthroline-2,9-dicarboxylate ligands in a distorted dodecahedral geometry. The double negative charge is balanced by two ethanamidinium cations. A three-dimensional supramolecular structure is formed through N—H...O and O—H...O hydrogen bonds and π–π stacking interactions [centroid–centroid distance = 3.553 (2) Å].
