W. Uhl et al., IN-4(C(SIME(3))(3))(4) WITH IN-4-TETRAHED RON AND IN4SE4(C(SIME(3))(3))(4) WITH IN4SE4-HETEROCUBANE STRUCTURE, Journal of organometallic chemistry, 493(1-2), 1995, pp. 1-5
The reaction of (InBr)-Br-I with LiC(SiMe(3))(3) . 2THF yields the In(
I) alkyl In-4{C(SiMe(3))(3)}(4) 1 in 70% yield. 1 was characterized by
a crystal structure determination showing a nearly undistorted In, te
trahedron with mean In-In distances of 300.2(1) pm. Reaction of 1 with
elemental Se gives In4Se4{C(SiMe(3))(3)}(4) 2 with a slightly distort
ed In4Se4 hetero cubane structure.
