A New 5-Connected Cu(II) Complex with 5-Bromoisophthalic Acid: Synthesis, Crystal Structure, and Properties.

A new coordination polymer, {[Cu(Brip)(1,4-btb)1.5]·2H2O}n, (H2Brip = 5-bromoisophthalic acid, 1,4-btb = 1,4-bis(triazol) butane) was prepared under hydrothermal condition by the reactions of Cu(II) acetate with H2Brip and 1,4-btb. The title complex was determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis and IR spectroscopy. Complex 1 has a 3D network extended by both H2Brip and 1,4-btb ligands that employ the same bis-monodentate bridging coordination modes. From the view of topology, the structure of 1 could be described as a 5-connected (44·66)-nov net. Two of such nets penetrate with each other to generate a 2-fold interpenetrating 3D network. In addition, the thermal stability of the title complex was briefly investigated. [ABSTRACT FROM AUTHOR]
