title: Hexaaqua-manganese(II) dipicrate dihydrate.
abstract: In the title compound, [Mn(H(2)O)(6)](C(6)H(2)N(3)O(7))(2)·2H(2)O, the manganese cation, on an inversion centre, is coordinated by six water mol-ecules, but the picrate anion has no coordinative inter-action with the manganese cation. The anions in the stack are linked via short inter-molecular O⋯C (3.013 and 2.973 Å) and C⋯C (3.089 and 3.065 Å) contacts and hydrogen bonds.
