1 Source of materials
The starting material 2,2′-{[1,3-phenylenebis(methylene)]bis(oxy)}dibenzoic acid (0.05 mmol) and CuCl2 (0.05 mmol) were dissolved in a mixed solution of DMF–H2O (2 mL: 3 mL), and then heated in a 25 mL scintillation vial at 380 K for 48 h. After cooled to room temperature, the green block crystals suitable for single crystal X-ray diffraction were obtained.
2 Experimental details
The H atoms were sited at their idealized positions and refined through a riding mode on the parent atoms, with C–H = 0.96 Å (methyl), Uiso(H) = 1.5 Ueq(C), and C–H = 0.97 Å (methylene), Uiso(H) = 1.2 Ueq(C), and C–H = 0.93 Å (aromatic), Uiso(H) = 1.2 Uiso(C).
3 Comment
Supramolecular complexes featuring open channels, well-defined shapes, unique physical and chemical properties have drawn considerable attentions owing to their potential applications in catalysis, sensors and magnetism for decades. In this work, a binuclear copper complex was synthesized under solvothermal condition, 4 and its crystal structure was also determined.
Single crystal X-ray diffraction reveals that the title compound is a binuclear complex. The molecular structure is shown in the figure. As exhibited in the figure, each copper ion is coordinated by five oxygen atoms from two carboxylato ligands and one DMF molecule forming a distorted tetragonal pyramid geometry. The Cu–O bond lengths in the paddlewheel-like complex range from 1.951(2) to 2.130(2) Å, with an average of 1.991 Å. The O–Cu–O bond angles of the paddlewheel are within the range of 88.597(101) to 97.532(86)°. The distance of Cu1–Cu1a is 2.6017(5) Å, which is comparable to that of other copper compounds. 5 , 6
There are weak hydrogen bonds among neighbor copper complexes. For example, the C–H⋯O intermolecular hydrogen bonds, originated from the DMF and carboxyl oxygen of ligand or the benzene ring and carboxyl oxygen of ligand, connect with binuclear copper complexes to form an open 2-dimensional network along b axis.
