چکیده
|
A new compound, k8nb7as7o39, has been synthesized by solid-state reaction. it crystallizes in the triclinic system, space group p with unit-cell parameters a = 8.767(4)å, b = 12.260(4)å, c = 19.018(4)å, α = 106.530(2)°, β = 99.470(2)°, γ = 90.460(2)° and z = 2. the structure of the compound is solved and refined to r = 0.062 and ωr2 = 0.1540. the structural study of k8nb7as7o39 shows that the compound has a two-dimensional framework.
