The crystal structure of di(α-hydroxyisobutyrate)diaquo neodymium nitrate Nd(C₄H₇O₃)₂NO₃2H₂O 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)Å, β=92.38°, V=1632.OÅ³, Z=4, Dc=1.83g/cm³.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.
