Synthesis of dihalogenidoindium(III) ions by halide transfer involving tellurium compounds in the presence of hard and soft ligands

Crystal Structures of Gallium(III) Halides with Bulky Ligands

“…For all three halides, the gal lium(III) metal is located at a site of tetrahedral geometry with three coordinated halide (Cl − , Br − or I − ) and one oxygen (phosphine oxide). The O-Ga bond distances increas slightly from Cl − to I − , as do the Ga-O-P bond angles, increasing from 158.66 (17) for Cl − 159.91( 16) for Br − and 163.88 (15) for the I − . The crystal structure for 2 was refined with two conformers of the GaBr 3 unit with a major (90%, labelled A) and minor (10%, labelled B) conformers, as shown in Figure 4a.…”

“…In addition to our solved crystal structures, there are 37 indium and gallium adduct crystal structures with triphenylphosphine and triphenylphosphine oxide ligands available from the CCDC database. Of interest to the present work are a few structures with triphenylphosphine oxide as ligands [11][12][13][14][15][16].…”

Oxygen, sulfur, selenium, tellurium and polonium

“…59 PhTeX 3 (X = Cl, Br) are acidic enough to abstract X À from In III halides forming [InX 2 L 2-4 ][PhTeX 4 ] salts with mono-and bi-dentate ligands such as OPPh 3 , DMSO and phen. 60…”
