Synthesis and Crystal Structure of a 3D Er(III) Coordination Polymer Based on Tripodal Flexible Ligand

Abstract

AbstractSolvothermal reaction of Er(NO 3 ) 3 ·6H 2 O and tri(2-carboxyethyl)isocyanurate (H 3 tci) in DMF/H 2 O (DMF = dimethylformamide) medium leads to the generation of one new 3D coordination polymer, [Er(tci)(H 2 O)] DMF·2H 2 O (1), which was characterized by the elemental analysis, IR spectroscopy and single crystal X-ray diffraction. X-ray diffraction analysis reveals that 1 crystallizes in triclinic space group P-1, features an interesting 3D coordination framework constructed from the flexible tridentate ligand H 3 tci. Unit cell parameters for 1: a = 7.853(2) A, b = 12.186(3) A, c = 13.222(2) A, α = 112.156(14)°, β = 105.457(15)°, γ = 91.541(18)° and Z = 2.Graphical AbstractSolvothermal reaction of Er(NO 3 ) 3 ·6H 2 O and tri(2-carboxyethyl)isocyanurate in DMF/H 2 O (DMF = dimethylformamide) medium leads to the generation of a 3D coordination polymer, which was characterized by the elemental analysis, IR spectroscopy and single crystal X-ray diffraction.
