[Mn2(C8H3NO6)2(C12H8N2)2]

R factor = 0.032; wR factor = 0.082; data-to-parameter ratio = 12.4. The title complex, [Mn2(C8H3NO6)2(C12H8N2)2]n, was synthe-sized under hydrothermal conditions. The structure contains two independent MnII atoms, each coordinated in a distorted octahedral MnN2O4 geometry. [Mn2(phen)2] units (phen = 1,10-phenantroline) are bridged by 5-nitroisophthalate (nip) ligands into ladder-like chains parallel to [100]. Adjacent polymeric chains are linked by C—H O and – inter-actions [centroid-to-centroid distance = 3.6369 (12) Å] into a two-dimensional framework parallel to (010).
