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].

The title compound was prepared by mixing two acetonitrile solutions (10 ml each) of Mn(NO3)2.4H2O (125.5 mg, 0.50 mmol) and 2,3,5,6-tetrakis(2-pyridyl)pirazine (97.1 mg, 0.25 mmol). After vigorous stirring for 3 h at a temperature of 30°C, a yellow precipitate appeared. To the resulting solution, a water/acetonitrile (50%) solution (10 ml) of sodium dicyanamide was added, and it was stirred at 40°C for 3 h, and then 2 days at room temperature. The precipitate was filtered off and yellow plaques formed from the resulting solution by slow evaporation at room temperature.
H atoms bonded to O atoms were located in a difference map and refined with distance restraints of O—H = 0.82 (2), and with Uiso(H) = 1.5Ueq(O). Other H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93 Å and with Uiso(H) = 1.2 times Ueq(C).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |

Only a few examples are known of coordination compounds with the ligands dicyanamido (dca) and 2,3,5,6-tetra-2-pyridylpyrazine (tppz) (Carranza et al., 2003; Hsu et al., 2005).
The molecule of the title compound (I) (Fig. 1) contains a central manganese(II) metal heptacoordinated to a terminal dicyanamide ligand, three nitrogen atoms of the tppz ligand, two oxygen atoms of the nitrate group, and one water molecule.
The central pyrazine ring of the tppz is severely distorted from planarity (N2—C11—C12—N5 = 20.9 (3)°, N2—C13—C14—N5 = 19.9 (2)°) and adopts a twist-boat conformation with a puckering amplitude of 0.215 (2)Å (Spek, 2003). The pyridyl rings are rotated away from planarity with the pyrazine ring, with angles between planes of 25.3 (1) and 21.5 (1)° for the ones coordinated to Mn(II), and larger [31.1 (1), 35.9 (1)°] for the other ones.
The O(water)—H···N hydrogen bonds formed between the water as donor, and a non-coordinated pyridyl ring and the coordinated nitrogen atom of dca as acceptors, generate chains of molecules along the [010] direction (Fig.2).
