The title compound, [Mn(C8H4N8)2(H2O)5]·2H2O, is the fourth transition metal complex containing the 1,3-di(2H-tetra­zol-5-yl)benzene ligand to be structurally characterized. The Mn^II^ cation has a distorted octahedral coordination geometry. The 1,3-di(tetra­zol-5-yl)benzene ligand is planar. All H atoms bonded to O atoms participate in hydrogen bonds, which link the mol­ecules into a framework structure.

Comment top

The 1,3-di(2H-tetrazol-5-yl)benzene (DHTB) ligand has hitherto been reported in the twice deprotonated form in the crystal structures of its complexes with zinc, cadmium and tin (Jiang et al., 2004; Hill et al., 1996), where it acts as a bridging ligand. This paper provides the first structural characterization of a DHTB complex with the transition metal Mn(II); the ligand in this complex is also twice deprotonated, but coordinated to the Mn atom as a terminal ligand.

The molecule of Mn(DHTB)(H2O)5 occupies a general position in the unit cell; the Mn atom has a non-distorted octahedral coordination as indicated by bond lengths and angles (Fig. 1). The DHTB ligand has an essentially planar conformation, with the maximum deviation from the mean plane being 0.054 (2) Å by atom C7. The geometry of the ligand is similar to that observed in Jiang et al. (2004) and Hill et al. (1996).

Strong ππ interactions between the aromatic rings are indicated by the short distance of 3.324 (3) Å between C1 and C8i [Symmetry code: (i) 1-x, 2-y, -z]. All hydrogen atoms that are bonded to oxygen atoms participate in H-bonding (Table 1); the extensive H-bond system and the strong ππ interactions link molecules of the complex and non-coordinated water molecules into a three-dimensional infinite network (Fig. 2).

Experimental top

The hydrothermal reaction of Mn(NO3)2 (0.5 mmol) and 1,3-di(2H-tetrazol-5-yl)benzene (0.5 mmol) in 20 ml of distilled water at 180°C for 3 days resulted in light yellow plate crystals of the title compound, in a yield of 42%. The crystals were filtered, washed with cold EtOH and dried in air.

Refinement top

All of the H atoms on carbon atoms were positioned geometrically and refined using a riding model with C—H = 0.93 Å and Uiso(H) = 1.2 times Ueq(C). All of the H atoms on oxygen atoms were located from the difference Fourier map, and refined freely, except for the bond length of O5—H5A being constrained to 0.87 Å.

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.
