摘要

Solvothermal reaction of Er(NO_3)_3?6H _2O and tri(2-carboxyethyl)isocyanurate (H_3tci) in DMF/H_2O (DMF = dimethylformamide) medium leads to the generation of one new 3D coordination polymer, [Er(tci)(H_2O)] DMF?2H _2O (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 H3tci. Unit cell parameters for 1: a = 7.853(2) ?, b = 12.186(3) ?, c = 13.222(2) ?, α = 112.156(14)°, β = 105.457(15)°, γ = 91.541(18)° and Z = 2.
