Abstract
In the title compound, [Mn(C2N3)(NO3)(C24H16N6)(H2O)], the central manganese(II) ion is heptacoordinated to a tridentate 2,3,5,6-tetra-2-pyridylpyrazine ligand (tppz), a bidentate nitrate ligand, a terminal monodentate dicyanamide ligand (dca) and a water molecule. The structure contains isolated neutral complexes, which are linked by O(water)—H⋯N hydrogen bonds generating chains along [010].

H atoms treated by a mixture of independent and constrained refinement max = 0.77 e Å3
A water/acetonitrile (50%) solution (10 ml) of sodium dicyanamide was added, and it was stirred at 40°C for 3 h, and 2 days at room temperature
