Source of material
A mixture of CoCl2⋅4H2O (0.048 g, 0.2 mmol), 1,2-bis(imidazole-1-ylmethyl)benzene (1,2-BIB) (0.046 g 0.2 mmol), benzene-1,2,4,5-tetracarboxylic acid (BTA)(0.025 g, 0.1 mmol), NaOH (0.008 g, 0.2 mmol) and H2O (10 mL) were stirred for about 30 min. The resulting solution was sealed in a Teflon-lined stainless autoclave and heated to 423 K for 3 days. The autoclave was cooled to ambient temperature spontaneously. Red single crystals (about 86%, based on Co input) were recovered by vacuum filtration and drying in air.
Experimental details
C-bound H atoms were geometrically placed (C—H = 0.95 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).
Discussion
The design and synthesis of coordination polymers (CPs) and especially metal organic frameworks (MOFs) have developed rapidly owing to applications of these materials in a variety of fields [1, 2] . The 1, 2-bis(imidazole-1-ylmethyl)benzene (1,2-BIB) is an important semi-flexible N-donor ligand, and some fascinating archetypal structures based on the 1,2-BIB ligand are reported [3, 4] . 1, 2, 4, 5-benzenetertracarboxylate (BTA) have also been extensively employed in the preparation of CPs [5]. Furthermore, it has been shown that the combination of carboxylate linkers along with semi-flexible N-donor ligands is a good choice for the construction of new CPs [6], [7], [8].
As shown in Figure, the asymmetric unit of the title compound contains two unique Co(II) atoms, one 1,2-BIB ligand, and two halves of BTA ligands. The Co1 center is six-coordinated with a distorted-octahedral geometry, defined by five oxygen atoms from three different BTA ligands, and one nitrogen atom from one 1,2-BIB ligand. The Co—N is 2.054(3) Å, and Co—O lengths are in the range of 1.969(2)–2.209(2) Å, which is comparable to values reported for related Co(II) complexes [4]. The Co2 atom is surrounded by one nitrogen donor from one 1,2-BIB ligand, as well as three oxygen atoms from different BTA anions, which exhibits a slightly distorted tetrahedron coordination sphere. The Co—O bond lengths range between 1.933(2) and 2.058(2) Å, while the Co—N bond length is 1.999(3) Å, which are in the normal ranges [4]. Both cyrstallographically independent BTA ligands are coordinated in an octa-dentate, coordination mode. They are located around different inversion centres of the triclinic space group (cf. the figure). Two symmetry-related carboxylate groups containing (O7, O8) of a BTA ligand are coordinated to two Co(II) atoms in chelating mode, while the other carboxylat groups are coordinated to four metal atoms in bridge-monodentate mode. The symmetry-related carboxylate groups (O1, O2) of the crystallographically independent BTA ligand act as a μ2-bridging function to connect two metal atoms in monodentated mode. Each of the two symmetry-related carboxylate groups of this second BTA ligand connect two metal atoms by its O3 and O3′ atom (cf. the figure). All these coordinations result in a two dimensional grid structure.
