摘要
The crystal structure of di-hydroxyisobutyrate)diaquo neodymium nitrate Nd(C_4H_7O_3)_2NO_32H_2O was determined by X-ray diffraction analysis. It belongs to monoclinic,space group C2/C,with cell dimensionsa=8.996(1), b=8.601(1),c=21.111(3),β=92.38°,V=1632.O,Z=4,D_c=1.83g/cm^3.Crystal structure has been refined by full-matrix least-square techniques giving a final R value of 0.036.The neodymium atom is coordinated to eight oxygen atoms.The nitrate group in complex is not bonded to neodymium,each two neodymium atoms are linked by bridging carboxyl group forming a chain polymeric molecule.
