On the reactions of the tetraindium cluster In4[C(SiMe3)3]4: Insertion of the monomeric fragments InC(SiMe3)3 into chalcogen-chalcogen bonds

Treatment of the tetraindium cluster In-4[C(SiMe3)(3)](4) (1) with diaryl dichalcogenides Aryl-E-E-Aryl (E = S, Se and Te) afforded the corresponding RIn(E-Aryl)(2) [R = C(SiMe3)(3)] compounds by insertion of the monomeric fragments InR into the chalcogen-chalcogen bonds. The dimeric formula units adopt different conformations in the solid state (C-i vs. C-2 (h)). (C) 2009 Elsevier B.V. All rights reserved.
