New heteroleptic indium compounds have been synthesized
group P-1. The central centrosymmetric In 2 O 2 ring, common to all the compounds, is achieved by two bridging oxygen starting from indium(III) halides and hexamethyldisilazyllithium to form MeXInN(SiMe 3 ) 2 [X = Cl (1), Br ( 2)], and then atoms. Due to the additional coordination by an oxygen atom of the methoxy group, the coordination number of the metal subsequent alcoholysis to afford the molecules [ClMeIn(OtBu)] 2 (3), [BrMeIn(OtBu)] 2 (4), {ClMeIn[O(C 6 H 4 )-center rises from 4 to "4+1" if the OtBu ligand (compounds 3, 4, 6, and 7) is exchanged for a methoxyphenol ligand OMe]} 2 (5), {[(SiMe 3 ) 2 N]MeIn(OtBu)} 2 ( 6) and [MeIn(OtBu) 2 ] 2 (7). The molecular structures of molecules 3-7 have been (compound 5). In addition to the In 2 O 2 ring the compound 5 possesses two annealed five-membered InO 2 C 2 rings. The obtained by single crystal X-ray diffraction studies. The structures of the compounds 3-7 are almost identical: 3-5 common indium methyl group of all compounds, which is transfered by an original route from the silicon to the indium crystallize in the monoclinic crystal system with two dimeric molecules per unit cell in the space group P2 1 /c, 6 crystallizes atom, is used to compare structural and spectroscopic properties of the molecules, as there is a correlation between in the monoclinic space group C2/c with four molecules per unit cell, and compound 7 crystallizes in the triclinic crystal the In-C bond length and the chemical shift of the methyl group which depends on the ligand system used. system with one dimeric molecule per unit cell in the space introduce selected ligands into indium-centered molecules, the disubstituted product ClIn[N(SiMe 3 ) 2 ] 2 .
