In the crystal structure of the title compound, [MnCl(2)(C(14)H(14)N(4))(2)](n), the Mn(II) atom, lying on an inversion center, is coordinated by four N atoms from four 1,4-bis-(imidazol-1-ylmeth-yl)benzene (bimb) ligands and two Cl(-) anions in a distorted octa-hedral geometry. The bimb ligands bridge the Mn(II) atoms, forming a two-dimensional polymeric complex, which is composed of a 52-membered [Mn(4)(bimb)(4)] ring with distances of 7.7812 (2) and 27.4731 (9) Å between opposite metal atoms. Weak C-H⋯π inter-actions are present in the crystal structure.
