Mf. Self et al., X-RAY CRYSTAL-STRUCTURE OF AN ORGANOINDIUM ALKOXIDE DIMER, (PH2INOSIME3)2, Journal of coordination chemistry, 29(1-2), 1993, pp. 27-32
The solid-state structure of (Ph2InOSiMe3)2, 1, has been established b
y single-crystal X-ray analysis. Monoclinic crystals of 1 belong to sp
ace group P2(1)/c, with a = 9.136(1), b = 15.503(2), c = 11.836(1) ang
strom, beta = 102.46(1)degrees, Z = 2. Refinement of atomic parameters
converged at R = 0.050 (R(w) = 0.063) over 1718 observed reflections
with I > 3.0sigma(I). The dimeric molecule lies on a crystallographic
centre of symmetry with In-O = 2.159(7) and 2.149(8) angstrom, O-In-O
= 78.9(3)degrees, and In-O-In = 101.1(3)degrees. Compound 1 is only th
e second example of a simple dimeric organoindium alkoxide to be struc
turally characterized in this manner.
