Abstract: | The neodymium phosphite Nd2(H2O)(HPO3)3 was hydrothermally synthesized. Single crystal X-ray diffraction (XRD) analysis showed that Nd2(H2O)(HPO3)3 crystallized in monoclinic P2(1)/n with cell parameters a=0.958 35(5) nm, b=0.797 70(4) nm, c=1.307 09(6) nm, β=10.886 6(3)°, V=0.945 56(8) nm3, Z=4. In addition, the structural analysis indicated that this compound had the three-dimensional structure which consisted of a network of alternatively linked corner-sharing HPO3 and NdO8 polyhedra. The physical properties of this compound were also characterized by infrared spectroscopy, thermogravimetric and differential thermal analyses, and magnetics property measurement. |
