Synthesis and crystal structure of a new acetate bridged metal-organic framework constructed by Pr (III) with 5-aminoisophthalic acid-[Pr(CH3COO)(AIP)(H2O)2]n.nH2O

摘要

A novel acetate bridged lanthanide complex [Pr(CH3COO) (AIP)(H2O)2]n×nH2O (PAIT) (H2AIP=5-aminoisophthalic acid) has been synthesized at room temperature by gel diffusion technique using hydro silica gel and structurally characterized by single crystal X-ray diffraction (CIF file CCDC no. 1857252). The title compound crystallizes in monoclinic space group, P21/c with a=10.5618(8) ?, b =12.1510(9) ?, c =10.7510(9) ?, α =90°, β =94.696(6)° , γ=90°. The Pr3+ ion has been coordinated by O9 donor sets to form distorted tricapped triagonal prism geometry. Its structure features a 3D polymeric network possessing ‘S’ shaped hydrophilic pores."
