catena-Poly[[diaqua­dichlorido­manganese(II)]-μ-1,1′-bis­(1H-1,2,4-triazol-1-ylmeth­yl)ferrocene]

In the title complex, [FeMn(C(8)H(8)N(3))(2)Cl(2)(H(2)O)(2)](n), the Mn(II) atom, located on an inversion center, is octa­hedrally coordinated by two N atoms from two adjacent 1,1′-bis­(1H-1,2,4-triazol-1-ylmeth­yl)ferrocene (btmf) ligands and two Cl atoms forming the equatorial plane, with the axial positions occupied by two O atoms of coordinated water mol­ecules. The btmf ligands link adjoining Mn(II) atoms into a zigzag chain along the a axis. The crystal structure is stabilized by inter­molecular O—H⋯N hydrogen bonds, which link the chains, forming a two-dimensional layer parallel to (10[Image: see text]); O—H⋯Cl inter­actions link the layers, forming a three-dimensional network.
