(last updated on 2026/01/21)Abstract:
The first four-membered ring compounds with bridging of the indium atoms by two arsenic atoms and with mixed bridging of the indium centers by one arsenic and one chlorine, [(Me3 SiCH2 )2 lnAs(SiMe3 )2 ]2 (1) and (Me3 SiCH2 )2 lnAs(SiMe3 )2 ln(CH2 SiMe3 )2 Cl (2), to be characterized completely were prepared by the reaction of (Me3 SiCH2 )2 InCl and (Me3 Si)3 As in 1:1 and 2:1 mol ratios, respectively. X-ray crystallographic analyses showed both the In-As-In-As ring of 1 and the In-As-In-Cl ring of 2 to be planar. Compound 1 belongs to the orthorhombic system, space group Pbcn (D142h), with four molecules in a unit cell of dimensions a = 12.920 (1) Å, b = 21.618 (2) Å, and c = 18.797 (2) Å. Compound 2 crystallizes in the monoclinic system, space group C2/c (C62h ), with four molecules in a unit cell of dimensions a = 19.233 (3) Å, b = 10.798 (2) Å, c = 20.819 (3) Å, and β = 105.91 (1)°. Compound 1 reacts with 2 equiv of (Me3 SiCH2 )2 lnCl to yield 2 as a major product, as evidenced by 1H and 13C{1H) NMR and melting point data. © 1991, American Chemical Society. All rights reserved.
