| Abstract: The title compound was synthesized and its crystal and molecular structure has been determined. The compound crystallizes in orthorhombic system and space group P212121 with lattice parameters: a=15.154(3),b= 18.234(3),c=24.010(4)Å;V=6634.5Å3;Z=4;Dc=1.751,Do=1.756g/cm3;M.W.=1748.60;F(000)=3468;μ=172.8cm-1. Refinement was carried out by the full-matrix least-squares. The structure was refined to a final R value of 0.068 for 4556 observational reflections. The coordination number of dysprosium of complex anion [Dy(NTA)2]3- is eight. The counter-ions of [Dy(NTA)2]3- are three [IC17N2H20]+. Certain interaction exists between anion and cations. |
