摘要：
The compounds R2InN(SO2Me)2 [R = Me (1), Me3SiCH2 (2) have been prepared by acidolysis of R3In with (MeSO2)2NH. 2 crystallizes in the monoclinic space group P2(1) with a = 1857.9(8), b = 1207.2(5), c = 1954.8(8) pm, beta = 108.60(3)-degrees, U = 4.155 nm3, Z = 8 monomers. The asymmetric unit contains two crystallographically independent dimers, in which the indium atoms are linked by two N-S-O bridges originating from two (MeSO2)2N- ligands to form an eight-membered [InNSO]2 ring (In-N 232-235, In-O 230-239 pm, C-In-C 136-150-degrees). Additionally, the two MeSO2 groups exocyclic to the eight-membered ring are weakly linked to the indium atoms in four-membered [InNSO] chelate rings (In ... O 253-261 pm). The indium atoms are thus five coordinate with very distorted (because of the four-membered rings) trigonal bipyramidal stereochemistry (O-In ... O 141-146-degrees, N-In ... O ca. 58-degrees), and are 6.3-25.8 pm out of the NC2 planes formed by the equatorial donor atoms.
