In the title compound, [Mn(CHO2)2(C12H10N4)2]n, the MnII atom and the benzene ring of the ligand lie on an inversion centers. The MnII atom has an octa­hedral coordination environment composed of four N atoms from two different symmetry-related N-heterocyclic ligands forming the basal plane, and two O atoms from symmetry-related formate anions occupying the apical positions. The title compound forms a two-dimensional (4,4) net parallel to (100) with all the MnII atoms lying on a plane. The crystal structure is consolidated by inter­molecular N—H⋯O hydrogen bonds..

Comment top

Recently, a great deal of interest in transition metal complex assembly has been devoted to the development of rational synthetic routes to novel crystal frameworks, due to their potential applications in many areas (Kitagawa et al., 1998). So far large quantities of novel coordination networks belonging to entangled systems have been reported in the literature (Batten et al., 1998). It has been demostrated that the flexible bridging ligand can easily construct entangled systems. For example, 1,4-bix(imidazol-1-yl-methyl) benzene (bix) formed an infinite polyrotaxane network of [Ag2(bix)3(NO3)2] by reactions with silver nitrate (Hoskins et al., 1997a) and gave a two-dimensional interpenetrated network of [Zn(bix)2(NO3)2.4.5H2O] by reactions with zinc nitrate which has both polyrotaxane and polycatenane characters (Hoskins et al., 1997b). As an extension of above work, we report a new entangled metal complex [Mn(C24H20N8)2(HCOO)2]n (I) based on rigid 1,4-di(1H-imidazol-4-yl)benzene ligand (L) and metal MnII salts. In the title compound, the Mn II atom and the ring benzene of the ligand are lies on inversion center. The MnII has an octahedral coordination environment surrounded by four nitrogen atoms from two different N-heterocyclic ligands symmetry-related forming the basal plane and two oxygen donors from one formate anion symmetry-related occupying the apical positions (Fig. 1). The Mn—N distances are comparable to those found in other crystallographically characterized MnII complex (Zhao et al., 2009) and Mn—O distance is coincident with another MnII complex (Zhu et al., 2010). The title compound form two-dimensional (4,4) net and its building unit is [Mn(L)]. The MnII are connected to a 1D linear chain along b-axis. The ligand, L, link MnII ions in adjacent chains by the same mode as described above, which makes the MnII ions links another 1D chain along c-axis. Therefore, the title compound is further connect to a 2D infinite strucure in bc plane, Fig. 2. The void spaces within the [Mn(L)2]n coordination polymer layers permit mutual inclined two parallel sets of layers to angle into three dimensional framework (Tian et al., 2007) (Fig. 3). The crystal structure of the title compound is stabilized by two intermolecular N—H···O interactions with average H···O distances 2.00 Å and N—H···O angles in the range 151-165°.

Experimental top

All reagents and solvents were used as obtained commercially without further purification. A mixture containing MnCl2.4H2O (19.8 mg, 0.05 mmol), L (27.6 mg, 0.1 mmol), DMF (N:N'- dimethylformamide, 1 mL), 10 ml H2O was sealed in a 16 ml Teflon-lined stainless steel container and heated at 393 K for 72 h. After cooling to room temperature within 12 h, block brown crystals of (I) suitable for X-ray diffraction analysis were obtained in 69% Yield.

Refinement top

H atoms bonded to C atoms were placed geometrically and treated as riding, with C—H distances 0.93 Å and Uiso(H) = 1.2Ueq(C). The amide H atoms were located from difference maps and refined with the N—H distances restrained to 0.86 Å and Uiso(H) = 1.2Ueq(N).

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.
