(Acetato-kappa O) diaqua[2-(1H-benzotriazol1-yl) acetato-kappa O](1,10-phenanthroline-kappa N-2,N ') manganese(II) dihydrate

In the hydrated title complex, [Mn(C 8H 6N 3O 2)(CH 3CO 2)(C 12H 8N 2)(H 2O) 2]·2H 2O, the Mn II atom is coordinated by two N atoms from a 1,10-phenanthroline ligand, two water O atoms, a monodentate acetate anion and an O-monodentate 2-(1H-benzotriazol-1-yl)acetate ligand, resulting in a distorted cis-MnN 2O 4 octahedral coordination geometry. The water O atoms are in a trans arrangement and one of them forms an intramolecular O - H⋯O hydrogen bond to the uncoordinated O atom of the acetate ion. In the crystal, the complex molecules and water molecules are connected by O - H⋯O and O - H⋯N hydrogen bonds to generate a three-dimensional network.
