A novel (4,6)-connected net based on dysprosium benzenedicarboxylate, Dy(OAc)(BDC) (n)

A new lanthanide coordination polymer, [Dy(OAc)(BDC)]n 1 (OAc = acetate, BDC = 1,4-benzenediacarboxylate), has been synthesized under hydrothermal conditions. Single-crystal X-ray diffraction analysis reveals that complex 1 has infinite zigzag Dy-OAc chains, which are further connected by BDC to form a 3D metal-organic framework. According to topology analysis, this framework can be characterized as (4,6)-connected (3.4.54)(32.4.56.66) net that has never been reported before. Crystal structure for 1: space group Pbca, a = 13.314(3), b = 8.0269(18), c = 20.275(5) , V = 2166.8(9) 3, C10H7O6Dy, Mr = 385.66, Z = 8, Dc = 2.364 g/cm3, μ = 6.910 mm–1, F(000) = 1448, the final R = 0.0181 and wR = 0.0520.
