The molecular title compound, [MnCl(2)(C(5)H(5)N)(2)(H(2)O)(2)], lies about an inversion centre. The Mn(II) atom is in an all-trans octa-hedral environment defined by two water mol-ecules, two chloride anions and two pyridine ligands. An inter-molecular hydrogen-bonding inter-action between a water mol-ecule and a chloride anion bonded to an adjacent Mn(II) atom generates an eight-membered ring. The crystal packing exhibits two inter-molecular π-π stacking inter-actions between the aromatic rings, with centroid-centroid distances of 3.485 (12) and 3.532 (12) Å.
