Reaction of LiE(SiMe3)2 with compounds containing four-membered cores of the general formula [cyclic] MEM(Cl) (M = In, E = As, P; M = Ga, E = As): novel rearrangement reactions to form the adducts R3M.cntdot.As(SiMe3)3 (R = Me3SiCH2, M = In; R = Ph, M = Ga)

Coordination chemistry of the main group elements with phosphine, arsine and stibine ligands

“…The syntheses are straightforward involving combining the GaR 3 with ER 3 either in a hydrocarbon or without a solvent [141,194,196,198,199,201]. Triarylgallium examples are fewer but generally similar [198,203].…”

“…The structure of [In(Me 3 SiCH 2 ) 3 {As(SiMe 3 ) 3 }] appears unexceptional [201], but those of [In(Me 3 CCH 2 ) 3 {E(SiMe 3 ) 3 }] (E = P or As) each contain three independent molecules, with significant variations in the structural parameters between them ascribed to the effects of steric crowding [237]. The weaker In-C bonds also produce some differences from the chemistry of the lighter analogues.…”

Alkylindium Subhalides Derived from the Tetrahedral Indium(I) Cluster Compound [In4{C(SiMe3)3}4]

“…Similarly, the intramolecular Cl´´´Cl distances (367.4 pm) correspond to the sum of the van der Waals radii (340 to 380 pm). [16] Many organoelement compounds bearing In-Cl-In bridges have been described, [17,18] the InÀCl bond lengths observed for 2 (259.1 to 265.3 pm) are in the normal range. As observed in most secondary products of 1, the InÀC bond lengths are a little shorter than those of the cluster compound 1 (221 compared to 225 pm of 1).…”

“…Diese a È hneln damit mehr den terminalen In±Cl-Bindungen z. B. in Chlorometallaten wie InCl 4 ± [30] und MeInCl 3 ± [31] oder in Addukten wie Cl 3 In´3 THF [32] und i PrInCl 2´D ioxan [33]. Weitere, jedoch unauffa È llige Moleku È lparameter sind in Tab.…”
