Abstract top

In the title coupound, [Mn(C9H6O4)(C12H8N2)]n, the MnII ion is coordinated by two N atoms [Mn-N = 2.273 (3) and 2.305 (2) Å] from a 1,10-phenanthroline ligand and four O atoms [Mn-O = 2.112 (2)-2.343 (3) Å] from three 5-methylisophthalate (mip) ligands in a distorted octahedral geometry. Each mip dianion acts as a tetradentate ligand connecting three Mn ions. The crystal packing exhibits [pi]-[pi] interactions [3.599 (2)-3.755 (2) Å] between the centroids of the six-membered rings of neighbouring 1,10-phenanthroline ligands.

Comment top

The rational design and syntheses of novel coordination polymers have achieved considerable progress in the field of supramolecular chemistry and crystal engineering, owing to their potential applications as gas storage, sensor technology, separation processes, ion exchange, luminescene, magnetism, and catalysis, as well as due to their intriguing variety of architectures and topologies. It has also been proved that careful selection of an appropriate multidentate bridging ligands provides further impetus for the investigation of metal-organic structural architectures as well as potential technological applications. So multicarboxylate acid 1,3-benzenedicarboxylates (H2bdc) with variously oriented carboxylate groups have widely been utilized to construct coordination polymers (Pan et al., 2006; Yang et al., 2002; Ma et al., 2008). Herewith we present the title polymeric compound, (I).

The asymmetric unit of (I) contains one MnII cation, one phen (= 1,10-phenanthroline) ligand and one mip (H2mip=5-methylisophthalic acid) anion. Each Mn ion is octahedrally coordinated by two N atoms of one phen ligand and four oxygen atoms from three mip ligands (Fig. 1). The Mn-N bond lengths are 2.273 (3), 2.305 (2) A° and the Mn-O bond lengths are in the range of 2.112 (2) - 2.343 (3) A°, which are similiar to those reported for nearly isostructural complex (Nie et al., 2001). X-ray structure analysis reveals that (I) consists of 1D chains bridged by mip anions. Each mip anion acts as a tetradentate ligand connecting three Mn ions. Two carboxylic groups of mip ligand have two coordination modes, one bidentately bridging two Mn ions in a syn-syn fashion and the other chelating one Mn ion. Along the (110) direction, the Mn ions are bridged by the mip anions to generate stranded polymeric ribbon containing alternative 8- and 16-membered rings (Fig. 2). Two carboxylic groups bridge two Mn (II) ions to form an 8-membered ring and two mip ligands bridge two Mn (II) ions to form a 16-membered ring. Within the 8-membered ring and 16-membered ring, the Mn—Mn separations are 4.013 (3) and 7.62 (7) A°, respectively.

Close stacking of aromatic rings is observed in the complex, the distances between their centroids from neighboring phen ligands are 3.599 (2)-3.755 (2) A° (Table 1).

Experimental top

A mixture of 5-methylisophthalic acid (0.2 mmol, 37 mg), phen (0.1 mmol, 21 mg) and Mn(OAc)2.4H2O (0.1 mmol, 24 mg) in distilled water (15 mL) and ethanol (1mL) was placed in a Teflon-lined stainless steel vessel, heated to 120 ° for 4 days, and then cooled to room temperature over 48 h. Yellow block crystals of (I) were obtained.

Refinement top

The H atoms were positioned geometrically (C—H 0.93-0.96Å), and treated as riding on their parent atoms, with Uiso(H) = 1.2-1.5Ueq(C).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
