| Abstract: | Abstract: Single crystals of gadolinium–sodium polyphosphate NaGd(PO3)4 were grown for the first time using a flux method and characterized by X-ray diffraction. This phosphate crystallizes in a monoclinic system with P21 /n space group and with the following unit-cell dimensions: a =9.767(3)Å, b =13.017(1)Å, c =7.160(2)Å, β =90.564(5)°, V =910.3(4)Å3 and Z =4. The crystal structure was solved from 3451 X-ray independent reflections with final R(F 2)=0.0219 and R w(F 2)=0.056 refined with 164 parameters (). The atomic arrangement can be described as a long chain polyphosphate organization. Two infinite (PO3)∝ chains with a period of eight tetrahedra run along the [011] direction. The structure of NaGd(PO3)4 consists of GdO8 polyhedra sharing oxygen atoms with phosphoric group PO4. Each Na+ ion is bonded to eight oxygen atoms. [Copyright &y& Elsevier] |
