Title: Explorations of new selenites of the group IIIA and IVA metals

Abstract

Systematic explorations of new phases in the Ga{sup III}/In{sup III}/Ge{sup IV}-Se{sup IV}-O systems by hydrothermal syntheses or solid-state reactions at high-temperature led to six new ternary compounds, namely, M{sub 2}Se{sub 2}O{sub 7} (M=Ga 1, In 2), M(OH)(SeO{sub 3}) (M=Ga 3, In 4), {alpha}-Ge(SeO{sub 3}){sub 2}5 and {beta}-Ge(SeO{sub 3}){sub 2}6. Ga{sub 2}Se{sub 2}O{sub 7}1 displays a 3D open framework composed of 2D gallium oxide layers being further bridged and capped by SeO{sub 3} groups. In{sub 2}Se{sub 2}O{sub 7}2 features a 3D indium oxide framework formed by corner- and edge- sharing InO{sub 6} octahedra with SeO{sub 3} groups attached on the cavities and the 8-member ring tunnels of the structure. The isostructural of M(OH)(SeO{sub 3}) (M=Ga 3, In 4) exhibit a 2D metal selenite layer composed of 1D edge-sharing MO{sub 6} octahedral chains that are interconnected by SeO{sub 3} groups. {alpha}-Ge(SeO{sub 3}){sub 2} (P2{sub 1}/n) 5 displays a 3D open framework with 1D 8-member ring tunnels along the a-axis while {beta}-Ge(SeO{sub 3}){sub 2} (Pa-3) 6 exhibits a condensed 3D network. - Graphical abstract: Highlights: Black-Right-Pointing-Pointer Up to now, selenites of the group IIIA and IVA metals are still rare.
