Disodium dimanganese(II) trioxalate dihydrate

X.-Y. Huang and Y.-L. Wang

Abstract top

In the crystal structure of the title compound, poly[di-[mu]2-aqua-di-[mu]5-oxalato-[mu]4-oxalato-disodiumdimanganese(II)], [Na2Mn2(C2O4)3(H2O)2]n, one of the oxalate ions lies on an inversion centre. The Mn atom is six-coordinate and Na is seven-coordinate; two of the oxalate ions bridge in a [mu]5 mode and the third in a [mu]4 mode. The Mn atoms are bridged into a ladder motif; neighbouring ladders are bridged by the water molecules and Na atoms into a three-dimensional network structure. Water-oxalate hydrogen bonds exist in the structure.

Comment top

Carboxylate ligands have been extensively studied because of their versatile coordinating modes in the coordination chemistry (Moulton & Zaworotko, 2001; Yaghi et al., 1996). Oxalate (ox) ligand is an important carboxylate ligand as it has a multiple coordinating modes, which together with the varied coordination geometry of metal ions has led to the generation of products containing one-dimensional chains, two-dimensional layers and three-dimensional frameworks (Castillo et al., 2005; Naumov et al., 1995; Bataille & Louër, 1999). The hydrothermal reaction of MnCl2 with Na2(ox) and oxalic acid yields the title complex, (I). We present its structure here.

The asymmetric unit of (I) consists of one manganese(II) ion, one sodium(I) ion, one and half ox dianions, and one coordinated water molecule. As depicted in Fig. 1, the Mn atom is six-coordinated by four oxygen atoms from three dianionic ox ligands in a distorted square planar geometry, and two oxygen atoms from water molecule and ox ligand in the apical positions. The bond dimensions involving Mn are normal (Table 1), and are comparable to the values in related manganese (II) complexes (Wu et al., 2005). The Na atom is seven-coordinated by seven O atom from four dianionic ox ligands, and one water molecule with the Na—O bond lengths varying from 2.302 (2)–2.712 (2) Å, which are comparable to the values in the [Na2Co2(ox)3(H2O)2] n compound (Price et al., 2000).

It is interesting that the coordinated water molecule displays a µ2 coordinating mode bridgeing the Mn1 and Na1 atoms, which further bridge by a µ2carboxlate O atom to form a 4-membered NaMnO2 ring with a Na···Mn separation of 3.55 Å (Fig. 1). Two types of ox ligands are observed in this structure. One is located on an inversion centre with a coplanar conformation and bridgs two Mn atoms and two Na atoms, in which each O atom is exhibits a µ2 coordinating fashion. The other displays a nonplanar conformation with the two carboxylate groups twisted with a dihedral angle of 19.8 (5) °. It bridgs two Mn atoms and three Na atoms using its two mondentate O atoms, one µ2-O atom and one µ3-O atom. The Mn ions are linked by the ox lignads to form a one-dimensional ladder structure propagating along a axis, as shown in Fig.2. The ladder is repeated by translation about every 5.9 Å along the a direction, comparable to the length of the a axis. The ladders are further connected by the Na ions and water molecules through the Na—O bonds to produce a three-dimensional structure, as shown in Fig. 3. The O—H···O hydrogen bonds between the water molecules and oxalate O atoms are observed in the three-dimensional structure with a O···O distances of 2.688 (2) and 2.824 (2) Å, respectively (Table 2).

Experimental top

The title compound was synthesized by a hydrothermal method under autogenous pressure. A mixture of MnCl2·4H2O (0.269 g,1 mmol), Na2C2O4 (0.268 g, 2 mmol), H2C2O4 (0.180 g, 2 mmol), and 15 ml distilled water was stirred under ambient conditions. The final mixture was sealed in a 25 ml Teflon-lined steel autoclave and heated at 423 K for 3 days, and then cooled to room temperature. Colorless prism crystals of (I) were obtained, and these were recovered by filtration, washed with distilled water and dried in air (yield 32%). Analysis calculated for C6H4O14Mn2Na2: C 15.81, H 0.88%; found: C 15.92, H 0.90%.

Refinement top

The H atoms bonded to O atoms were visible in difference maps and refined with a DFIX restraint (SHELXTL; Sheldrick, 1997b) of O—H = 0.90 Å and with Uiso(H) = 1.5Ueq(O).

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 > 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.
