A new three-dimensional manganese(II) coordination polymer based on the 1,3,5-tris­[(1H-imidazol-1-yl)meth­yl]benzene ligand

The self-assembly of coordination polymers and the crystal engineering of metal–organic coordination frameworks have attracted great inter­est, but it is still a challenge to predict and control the compositions and structures of the complexes. Employing multidentate organic ligands and suitable metal ions to construct inorganic–organic hybrid materials through metal–ligand coordination and hydrogen-bonding inter­actions has become a major strategy. Recently, imidazole-containing multidentate ligands that contain an aromatic core have received much attention. A new three-dimensional Mn^II coordination polymer based on 1,3,5-tris­[(1H-imidazol-1-yl)meth­yl]benzene, namely poly[(ethane-1,2-diol-κO)(μ-sulfato-κ²O:O′){μ₃-1,3,5-tris­[(1H-imidazol-1-yl)meth­yl]benzene-κ³N:N′:N′′}manganese(II)], [Mn(SO₄)(C₁₈H₁₈N₆)(C₂H₆O₂)]_n, was syn­thesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal structural analysis shows that there are two kinds of crystallographically independent Mn^II centres, each lying on a centrosymmetric position and having a similar six-coordinated octa­hedral structure. One is coordinated by four N atoms from four 1,3,5-tris­[(1H-imidazol-1-yl)meth­yl]benzene (timb) ligands and two O atoms from two different bridging sulfate anions. The second is surrounded by two timb N atoms and four O atoms, two from sulfate anions and two from two ethane-1,2-diol ligands. The tripodal timb ligand bridges neighbouring Mn^II centres to generate a two-dimensional layered structure running parallel to the ab plane. Adjacent layers are further bridged by sulfate anions, resulting in a three-dimensional structure with 3,4,6-c topology. Thermogravimetric analysis of the title polymer shows that it is stable up to 533 K. The first weight loss between 533 and 573 K corresponds to the release of coordinated ethane-1,2-diol mol­ecules, and further decomposition occurred at 648 K.

Special details

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.
