摘    要:A new niobate compound KSr2Nb3O10 was synthesized for the first time. The chemical compositions, crystal structure, optical property, density and melting point of the new compound were characterized by EPMA, TEM, XRD, DTA and so on. KSr2Nb3O10 crystallizes the orthorhombic system with unit cell parameters a=0.7816(1) nm, b=0.7764(2) nm, c=2.9995(2) nm, V=1.8114(4) nm3, and space group P212121, Z=8. The structure may be described as treble perovskite sheets [Sr2Nb3O10- interleaved with K+. Further, it was found that KSr2Nb3O10 has intercalation phenomenon. Na+, Li+, H+, NH+4 could exchange the interlayer cations K+ of KSr2Nb3O10, and n-hexylamine also could intercalate into the place between the layers of [Sr2Nb3O10-.

Abstract:; A new niobate compound KSr\-2Nb\-3O\-\{10\} was synthesized for the first time. The chemical compositions, crystal structure, optical property, density and melting point of the new compound were characterized by EPMA, TEM, XRD, DTA and so on. KSr\-2Nb\-3O\-\{10\} crystallizes the orthorhombic system with unit cell parameters \%a\%=0.7816(1) nm, \%b\%=0.7764(2) nm, \%c\%=2.9995(2) nm, \%V\%=\{1.8114(4)\} nm\ 3, and space group \%P\%2\-12\-12\-1, Z=8. The structure may be described as treble perovskite sheets \ - interleaved with K\ . Further, it was found that KSr\-2Nb\-3O\-\{10\} has intercalation phenomenon. Na\ , Li\ , H\ , NH\ \-4 could exchange the interlayer cations K\ of KSr\-2Nb\-3O\-\{10\}, and nhexylamine also could intercalate into the place between the layers of \ -.
