The title polymeric compound, [Mn2(C10H2O8)(C12H8N2)2]n, was obtained by the reaction of manganese(II) chloride tetrahydrate with benzene-1,2,4,5-tetracarboxylic acid (H4bta) in aqueous solution. Each Mn2+ ion is coordinated in a distorted octahedral geometry by two N atoms from one 1,10-phenanthroline ligand and four O atoms [Mn—O = 2.116 (2)–2.237 (2) Å] from three bta4− ligands, which also act as bridging groups between the Mn2+ ions.

All reagents and solvents were used as obtained without further purification. MnCl2.4H2O (59 mg,0.3 mmol), H4bta (76 mg, 0.3 mmol) and NaOH (24 mg, 0.6 mmol) were dissolved in 10 ml of distilled water. The mixture was sealed in a Teflon-lined stainless steel vessel and kept at 443 K for one week. The vessel was gradually cooled to room temperature, and brown crystals suitable for crystallographic analysis were obtained after two weeks. These latter crystals were filtered, washed with water, and dried in air. Yield: 32 mg (30%) based on Mn.
Positional parameters of all H atoms were calculated geometrically and were allowed to ride on their corresponding parent C atoms, with Uiso(H) = 1.2Ueq(C).

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. |

The recent interest in the crystal engineering of special geometrical and topological coordination polymers arises from their potential application in catalysis, chemical absorption, magnetism and electrical conductivity (For related structures, see: Rao et al., 2000). The benzene-1,2,4,5-teracarboxylate ligand (bta) as a multi-connecting ligand is also an excellent candidate for the structuring of coordination polymers, and comparatively few examples have been reported to date in relation to applying it to the building of coordination polymers (For details of the preparation of related compounds, see: Aghabozorg et al., 2007; Chu et al., 2001; Liu & Ding, 2007; Wu et al., 2006). We report here the synthesis and crystal structure of the title complex, (I) (Fig. 1).
As shown in Fig.1, only one bta ligand is located in the crystallographic asymmetric unit, while each bta ligand is shared between three manganese(II) centres. The manganese atom is situated on an inversion centre and is coordinated in a trans mode by one chelated phen ligand [Mn—N = 2.252 (3) and 2.305 (3) Å] and four carboxylate oxygen atoms [Mn—O = 2.116 (2), 2.125 (2), 2.204 (2) and 2.237 (2) Å] (Table 1) from three distinct bta ligands. The coordination geometry around the MnII ion is slightly distorted octahedral. The O1 and O4 atoms occupy trans positions. Each bta ligand bridges to six manganese atoms to generate a two-dimensional sheet architecture, in which the carboxylate groups of the bta ligand all display a bridging mode (Fig. 2). Along the crystallographic a-axis, the manganese atoms are maintained in a pseudo-chain arrangement with a Mn···Mn distance of 4.611 Å (Fig. 3).
