Source of material

A mixture of Cu(OAc)2 ⋅ H2O (0.1 mmol, 19.9 mg), 5-tert-butyl isophthalic acid (tbipH) (0.1 mmol, 25.5 mg), 1,4-bis(triazol-1-ylmethyl)benzene (btb) (0.1 mmol, 23.0 mg), and 12 mL deionized water was sealed in a Teflon-lined stainless vessel (25 mL) and heated at 413 K for 72 h, then cooled slowly to room temperature. Blue block crystals were obtained by filtration.

Experimental details

The hydrogen atoms were placed in calculated positions riding on attached atoms with Uiso = 1.2Ueq(C). The methyl groups were idealized and refined using rigid groups allowed to rotate about the C—C bond (AFIX 137 option of the SHELX program [3]). The Uiso values of the hydrogen atoms of methyl groups and oxygen were set to 1.5Ueq(C, O).

Discussion

Current interest for the crystal engineering of coordination polymers has attracted much attention not only because of their potential application in many fields, but also for their intriguing structures and topologies [4], [5], [6], [7]. Many factors, such as the coordination geometry of the metal ions, solvent systems, and metal-to-ligand ratios, have been found to influence the topology of coordination polymers. The selection of organic bridging ligands plays a crucial role in the synthesis. For example, 5-R-isophthalic acids with special conformation (such as an angle of 120° between two carboxyl groups) and versatile coordination fashions, may provide the potential to construct unpredictable polynuclear clusters [8, 9] .

Each Cu(II) center is four-coordinated with a distorted tetrahedral coordination geometry, by two oxygen atoms (Cu1—O1/O1A = 1.9643(19) Å) from two tbip anions and two nitrogen atoms (Cu1—N1/N1A = 2.019(2) Å) from two btb ligands. The btb ligand connect the Cu(II) center to form a polymeric chain. Two partially deprotonated tbip anions camplete the coordination. Each polymeric chain is extended to form a 2D supramolecular layer through C—H⋯O hydrogen-bonds between triazol groups and carboxylate oxygen atoms.
