Abstract top

In the title coordination polymer, {[Mn(C7H3NO4)(H2O)2]·2H2O}n, the MnII ion is coordinated in a distorted octahedral environment by the O atoms of two water molecules, one N and one O atoms of the chelating pyridine-2,3-dicarboxylate (PDC) dianion, and two axial bridging carboxylate O atoms from two adjacent PDC ligands. The fully deprotonated PDC anion acts a [mu]3-bridging ligand, establishing a chain structure along the a axis. These polymeric chains are connected into a three-dimensional framework via several intermolecular O-H...O hydrogen bonds.

Comment top

Pyridine-2,3-dicarboxylic acid (H2PDC), being a potential multidentate bridging ligand, has aroused considerable interests in recent decades and a number of metal complexes have been reported. In these complexes, pyridine-2,3-dicarboxylic acid is partly or fully deprotonated and shows diverse coordination modes, such as non-coordinate (Takusagawa & Koetzle, 1978; Manteghi et al., 2007), monodentate (Drew et al., 1971; Ghoer & Youssef, 1993; Patrick et al., 2003; Baruah et al., 2007), µ2-bridging (Zhang et al., 2003; Aghabozorg et al., 2007; Sun et al., 2006; Turner & Batten, 2007; Kang et al., 2006), µ3-bridging (Zhang & You, 2003; Li et al., 2006). Here we describe another new compound in which the PDC is µ3-bridging, (I),(Fig. 1).

Complex (I) is composed of {[Mn(C7H3NO4)(H2O)2].2H2O}n units, in which the MnII ion is six-coordinated in a distorted octahedral geometry (Table 1) formed by two coordinated water molecules, one N and one O atoms of a PDC dianion and two different carboxylate O atoms in the axial position from another two adjacent PDC ligands. The deprotonated PDC are µ3-bridging ligands and they join the neighbouring MnII ions to form this one-dimensional linear chain structure along a axis. This kind of µ3-bridging mode is different from that have been published (Zhang & You, 2003; Li et al., 2006) as in this paper one bridging carboxylate O atom only links one metal ions, while in the latter one bridging carboxylate O atom simultaneously links two metal ions,respectively.

The carboxylate O atoms of PDC dianion and coordinate and non coordinated water molecules are all involved in rich O—H···O intermolecular hydrogen bonds (Table 2) and they connect polymetric chains into a three-dimensional framework (Fig. 2).

Experimental top

The ligand H2PDC (1 mmol, 0.17 g) and NaOH (2 mmol, 0.08 g) were dissolved in water and methanol mixed solvent (20 ml, v/v 1:1). To this solution, Mn(CH3COO)2.4H2O (1 mmol, 0.25 g) was added and the resulting mixture was stirred and refluxed at 343 K for 5 h, then cooled to room temperature. After filtration and evaporation in air for a week, pink block-shaped crystals were obtained in a yield of 37%. Analysis, found (%): C, 28.70; H, 3.80; N, 4.71. C7H11Mn N O8 requires (%): C,28.75; H,3.76; N,4.79. (CCDC number 668395)

Refinement top

H atoms bonded to C atoms were positioned geometrically with C—H distance of 0.93 Å, and treated as riding atoms, with Uiso(H) = 1.2Ueq. H atoms bonded to O atoms were located in a difference Fourier map and refined isotropically.

Special details top

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.
