Abstract
Organic-inorganic compound [NH2(CH2)2NH2]6H8[Na2Mo12O30(H2PO4)6(HPO4)2]·4H2O has been prepared under hydrothermal conditions,characterized by elemental analysis,IR and single crystal X-ray diffraction analysis.The title compound crystallizes in the triclinic system,space group Pī,a =1.204 05(7) nm,b =1.461 47(8) nm,c=2.132 56(12)nm,α =80.650 0(10)°,β =82.808 0(10)°,γ =76.236 0(10)°,V =3.581 8(3) nm3,Z =2,R1= 0.046 5.The heteropolyanion contains two [NaMo6O15(H2PO4)3(HPO4)]4-cluster units linked through a O-Na(3)-O linkage.The six MoO6 octahedra in the [NaMo6O15(H2PO4)3(HPO4)]4-cluster are coplanar and construct a Mo6 ring by sharing edges.The NaO6 octahedron and four PO4 tetrahedra are located at the two faces of the Mo6 ring,respectively.
