A novel anionic three-dimensional indium phosphite-oxalate hybrid material, formulated as |C 6 H 14 N 2 |[In 2 (HPO 3 ) 3 (C 2 O 4 )] (1) was prepared under hydrothermal conditions by using 1,4-diazabicyclo[2.2.2]octane (dabco) as a structure directing agent (SDA). Single-crystal X-ray diffraction analysis reveals that compound 1 crystallizes in the orthorhombic system space group Pna2 1 (No. 33) having unit cell parameters a = 12.4143(13) Å, b = 7.7166(8) Å, c = 18.327(2) Å, V = 1755.6(3) Å 3 , and Z = 4 with R 1 = 0.0282, wR 2 = 0.0632. The novel 3D open framework is constructed from InO 6 octahedra, HPO 3 pseudo-tetrahedra and C 2 O 4 units. The assembly of these building units generates intersecting 8-and 12-membered ring (MR) channels along two different directions. To the best of our knowledge, it is the first reported indium phosphite-oxalate hybrid material. Further characterization of compound 1 was performed using X-ray powder diffraction (XRD), infrared (IR) spectra, thermal gravimetric analyses (TGA), inductively coupled plasma (ICP) and elemental analyses.

Indium(I)chloride reacts with LiAr Me 6 (Ar Me 6 = C6H3-2,6-(C6H2-2,4,6-Me3)2) in THF to give three new mixed-valent organoindium subhalides. While the 1:1 reaction of InCl with LiAr Me 6 yields the known metal-rich cluster In8(Ar Me 6)4 (1), the use of freshly prepared LiAr Me 6 led to incorporation of iodide, derived from the synthesis of LiAr Me 6 , into the structures, to afford In4(Ar Me 6)4I2 (2) along with minor amounts of In3(Ar Me 6)3I2 (3). When the same reaction was performed in 4:3 stoichiometry, the mixedhalide compound In3(Ar Me 6)3ClI (4) was obtained. Further increasing the chloride:aryl ligand ratio resulted in the formation of the known mixed-halide species In4(Ar Me 6)4Cl2I2 that can also be obtained from the reaction of InCl with in situ prepared LiAr Me 6 in toluene. The new compounds 2 and 4 were characterized in the solid state by X-ray crystallography and IR spectroscopy, and in solution by UV/Vis and 1 H/ 13 C{ 1 H} NMR spectroscopies. The structural characterization of 2 and 4 was supported by electronic structure calculations at the density functional level of theory which were also performed to rationalize the cluster-type bonding in 1.

2-Chloro-1,3-dioxo-2,3-dihydro-1H-inden-2-yl acetate, C 11 H 7 ClO 4 ( , has been synthesized and the structure has been solved by IR and X-ray diffraction studies. The crystals are triclinic, space group P " 1, with a = 7.62060(10) Å , b = 11.5944(2) Å , c = 13.0753(3) Å , a = 97.2820(10)°, b = 101.5740(10)°, c = 101.7930 (10)°, Mr = 238.62, V = 1090.82(3) Å 3 , Z = 4 and R = 0.0557. In the title compound there are two molecules in the asymmetric unit. The molecules are linked via weak C-HÁÁÁO hydrogen bonds forming R 4 4 (28) rings. The intermolecular interactions were analysed by means of the fingerprint plots derived from the Hirshfeld surfaces. The fingerprint plots evidenced subtle differences in the intermolecular contacts for the two independent molecules.

— Indium (III) Oxide (In2O3) nanomaterials w ere grown on glass and Si (100) substrates using the horizontal vapor phase crystal growth technique. A greater yield of nanomaterials was retrieved on the glass substrate than on the Si (100) substrate. Nanopyramids, nanooctahedrons, nanotriangles, and faceted nanoparticles were found at temperatures of 1200°C, 1000°C, and 800°C. EDX results of representative structures revealed an atomic composition of ~40 % indium and ~60% oxygen. XRD results revealed that the nanomaterials produced were indeed indium oxide and that the sample grow n on Si (100) has better crystallinity than those formed on glass. Transmission measurements confirm that the samples grown on the
Synthesis and Decomposition of a Novel Carboxylate Precursor to Indium Oxide
MRS Proceedings, 1993
Reaction of metallic indium with benzoyl peroxide in 4-methylpyridine (4-Mepy) at 25°C produces an eight-coordinate mononuclear indium(III) benzoate, In(1l2-02CC6HSh( 4-MepY)z'4H20 (I), in yields of up to 60%. The indium(1II) benzoate was fully characterized by elemental analysis, spectroscopy, and X-ray crystallography; (I) exists in the crystalline state as discrete eight-coordinate molecules; the coordination sphere around the central indium atom is best described as pseudo-square pyramidal. Thermogravimetric analysis of (I) and X-ray diffraction powder studies on the resulting pyrolysate demonstrate that this new benzoate is an inorganic precursor to indium oxide. Decomposition of (I) occurs fIrst by loss of 4-methylpyridine ligands (100°-200°C), then loss of benzoates with formation of In203 at 450°C. We discuss both use of carboxylates as precursors and our approach to their preparation.
