Abstract
In the title compound, {[Mn(C14H14N4)2(H2O)2](NO3)2}n, the MnII ion is located on an inversion center and is coordinated by four N atoms from four 1,3-bis(1H-imidazol-1-ylmethyl)benzene (L) ligands and two water molecules in a distorted octahedral geometry. Two L ligands are related by a centre of symmetry and bridge MnII ions, forming a positively charged polymeric chain in [101]. Uncoordinated nitrate anions further link these chains into layers parallel to the ac plane via O—H⋯O hydrogen bonds.
