Synthesis, crystal structure and magnetic properties of a one-dimensional Mn²⁺ complex constructed from (+)-dibenzoyltartaric acid and 2,2′-bipyridine

Y. Jiao, F.-N. Jin, S.-S. Feng, A. Wang and U. Englert

The self-assembly reaction of (+)-dibenzoyltartaric acid (D-H₂DBTA) with 2,2′-bipyridine (bpy) and Mn(CH₃CO₂)₂·4H₂O yielded a new coordination polymer, namely, catena-poly[[[diaqua(2,2′-bipyridine-κ²N,N′)manganese(II)]-μ-2,3-bis(benzoyloxy)butanedioato-κ²O²:O³] dihydrate], {[Mn(C₁₈H₁₂O₈)(C₁₀H₈N₂)(H₂O)₂]·2H₂O}_n or {[Mn(DBTA)(bpy)(H₂O)₂]·2H₂O}_n, (I). Complex (I) has been characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TGA) and single-crystal and powder X-ray diffraction. It crystallizes in the orthorhombic space group P2₁2₁2₁. In the complex, the Mn²⁺ cation displays a distorted octahedral {MnO₄N₂} geometry, formed from two carboxylate O atoms of two DBTA²⁻ ligands, two cis-oriented N atoms from one chelating 2,2′-bipyridine ligand and two trans-oriented O atoms from coordinated water molecules. The polymer displays a 1D chain with an Mn

Mn distance of 9.428 (1) Å. Due to the presence of flexible polycarboxylate and rigid bipyridyl ligands in the molecular structure, a high thermal stability of the complex is attained. The magnetic properties of (I) were analyzed based on the mononuclear Mn²⁺ model due to the long intramolecular Mn

Mn distance. The zero field splitting (ZFS) contribution in the high-spin Mn²⁺ cation is almost negligible and there are weak antiferromagnetic couplings between 1D chains [zJ′ = −0.062 (5) cm⁻¹], corresponding to an intermolecular Mn

Mn distance of 7.860 (2) Å.

Keywords: (+)-dibenzoyltartaric acid; D-H₂DBTA; manganese coordination polymer; crystal structure; 1D chain; thermostability; magnetism.

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. Multi-scan program SADABS was used for absorption correction (Sheldrick, 2008). The structures were solved by the direct method and refined by the full-matrix least squares method on F² using the SHELXS2018 (Sheldrick, 2015). All the non-H atoms were refined anisotropically.
