Three new d10 transition metal selenites containing PO4 tetrahedron: Cd7(HPO4)2(PO4)2(SeO3)2, Cd6(PO4)1.34(SeO3)4.66 and Zn3(HPO4)(SeO3)2(H2O)

Three new d10 transition metal selenites containing phosphate tetrahedron, namely, Cd7(HPO4)2(PO4)2(SeO3)2, Cd6(PO4)1.34(SeO3)4.66 and Zn3(HPO4)(SeO3)2(H2O), were synthesized successfully with hydrothermal reactions. The two Cd compounds feature new 3D frameworks consisted of CdO6 octahedra, PO4 tetrahedra and SeO3 groups.292
