Tetra-aqua-bis-[5-(pyridin-3-yl)tetra-zolido-κN⁵]manganese(II) tetra-hydrate.


The title compound, [Mn(C₆H₄N₅)₂(H₂O)₄]·4H₂O, was obtained by the solution reaction of MnCl₂ and 3-(2H-tetra-zol-5-yl)pyridine. The Mn(II) atom, located on an inversion center, shows a slightly distorted octa-hedral geometry and is coordinated by two pyridine N atoms from two 5-(pyridin-3-yl)tetra-zolide ligands occupying trans positions and four water mol-ecules. In the crystal, the mononuclear complex mol-ecules and solvent water mol-ecules are connected into a three-dimensional framework by O-H⋯N and O-H⋯O hydrogen bonds.
