Three new organically bonded indium(III) selenates or selenites, namely, In{sub 2}(2,2'-bipy){sub 2}(SeO{sub 4}){sub 3}(H{sub 2}O){sub 2}.2H{sub 2}O (1), In{sub 2}(2,2'-bipy){sub 2}(SeO{sub 4})(C{sub 2}O{sub 4}){sub 2}.0.5H{sub 2}O (2) and In{sub 2}(2,2'-bipy){sub 2}(SeO{sub 3}){sub 2}(C{sub 2}O{sub 4}) (3) (2,2'-bipy=2,2'-bipyridine) have been synthesized by hydro/solvothermal reactions by using the in situ ligand synthesis technique (2 and 3) and structurally characterized. The structure of compound 1 features a dimer composed of two InO{sub 4}N{sub 2} octahedra bridged by three SeO{sub 4} tetrahedra via cornering sharing. The structure of compound 2 shows a 2D inorganic-organic hybrid layer in which the indium (III) ions are bridged by both selenate and oxalate anions, whereas the structure of compound 3 possesses a 2D inorganic-organic hybrid layer composed of the indium (III) ions interconnected by both selenite and oxalate anions. The adjacent layers are further interconnected via {pi}...{pi} interactions between the bipy ligands. Compound 1 displays an intra-ligand luminescent emission band at {lambda}{sub max}=360 nm whereas compounds 2 and 3 both exhibit intra-ligand luminescent emission bands at {lambda}{sub max}=389 nm. - Graphical abstract: Three new organically bonded indium(III) selenates or selenites hybrids have been synthesized and characterized. Their structures feature organically bonded indium oxalate selenate or selenite layer or hydrogen-bonded 3D structures based on indium selenate dimers.
