To a solution of 2,9-dimethyl-1,10-phenanthroline (0.21 g, 1 mmol) and fumaric acid (0.058 g, 0.5 mmol) in ethanol (10 ml) was added a solution of Mn(Ac)2 (0.11 g, 1 mmol) in distilled water (10 ml). The mixture was stirred and then refluxed for 2 h. The hot solution was then filtered into another flask containing ethanol-water. Brown crystals appeared over a period of one week by slow evaporation at room temperature.
All H atoms were located in difference Fourier map. Water H atoms were refined with O1W—H1W1 and O1W—H2W1 distance restrains of 0.82 Å [1.5 Ueq(O)]. The remaining H atoms were placed in idealized positions and constrained to ride on their parent atoms, with C—H distances in the range 0.93–0.96 Å, and with Uiso(H) = 1.2 Ueq(C) and 1.5 Ueq(methyl C) H atoms.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Metal-phenanthroline complexes are good indicators for hydridization detection in DNA electrochemical biosensors (Wang et al., 1996). In our search for new indicators, the title complex was synthesized and its structure is presented here.
The binuclear manganese complex in (I) possesses a crystallographically imposed centre of symmetry (Fig. 1). Each MnII atom is six-coordinated by two N atoms from one 9,10-dimethyl-phennathroline ligand, one O atoms from water, one O atom from fumaric acid, and two O atom from nitrate anion in a distorted octahedral environment. The axial position is occupied by water molecule O atom and one N atom from 9,10-dimethyl-phennathroline ligand, with an O1W—Mn1—N1 bond angle of 167.68 (1)°.
In the crystal structure, the short interplanar distances between the phenanthroline moieties suggest strong π···π interactions. The distances between benzene rings are Cg1···Cg2iii = 3.826, Cg1···Cg3iii = 3.708 and Cg3···Cg3iii = 3.719 Å, where Cg1, Cg2 and Cg3 denote the centroids of N1/C2—C5/C13, N2/C8—C12 and C5—C8/C12/C13 rings, respectively, which contribure to the crystal packing [symmetry code: (i) -x + 1, -y, -z + 1]. The water molecules act as donors to form O—H···O hydrogen bonds (Table 2). Moreover, the molecules are linked into chains along the a axis by C6—H6A···O4 and C9—H9A···O1 intermolecular hydrogen bonds.
