Abstract : The dimers Ph(Me3SiCH2)InAs(SiMe3)22 (1), Me(Me3SiCH2)InAs(SiMe3)22 (2), Me(Me3SiCH2)InP(SiMe3)22 (3), and C1(Me3SiCH2)InP(SiMe3)22 (4) are reported. These compounds are produced via ligand exchange reactions involving the migration of either alkyl groups, for 1 - 3, or a chlorine atom, in the case of 4, from various group 13 species. Additionally, 3 and 4 can be prepared utilizing alternate routes involving a novel Si-C bond cleavage and reaction of (Me3SiCH2)InC12 with P(SiMe3)3, respectively. Compound 1 crystallizes in a trans configuration in the triclinic space group with unit cell parameters a 11.859(2) , b 12.222(2), c 10.021(2) A, a 107.59(1), Beta 110.47(1), gamma 66.54(1) deg, V 1225.6(7) A3 and Z = 1. Crystals of isostructural compounds 2 - 4 are isomorphous.
