One of the two 1,4-dicarboxylate dianions in the title compound, [Mn2(C12H6O4)2(C19H12N4)2]·C3H7NO, uses its two carboxylate groups to chelate two N-heterocycle-chelated Mn atoms; the other 1,4-dicarboxylate dianion binds to four such metal centers. The octahedrally coordinated Mn atoms are linked through the two dianions into a layer motif; the dimethylformamide molecules occupy the spaces between adjacent layers. Ten C atoms and attached H atoms of one dianion are disordered equally over two positions.
There are several studies of 2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene-chelated metal compounds; for the structures of the manganese dicarboxylate adducts, see: Che (2006); Che & Liu (2006); Wang et al. (2006); Zhang et al. (2006).
