Synthesis and Crystal and Molecular Structure of In(C5Me5)-An Apparent Octahedral Cluster.

Abstract

The new compound In(C5Me5) has been prepared and characterized by an X-ray structural study as an octahedral cluster. This new indium(I) compound is a golden yellow, volatile crystalling solid at room temperature. An X-ray structural study demonstrates that the compound crystallizes in the rhombohedral space group R3 (C superscript 2 sub 3i;No. 148) with unit cell parameters (hexagonal setting) a=20.182(4), c=13.436(3)angstrom, V-4739(2)angstrom and Z=18. The structure refined to R sub F=3.6% and R sub wF=3.3% for all 1870 unique data. The crystal consists of an octahedral cluster (In(C5Me5)6) with indium atoms on the interior and eta 5 -C5Me5 units on the exterior. All pentamethylcyclopentadienyl rings exhibit eta 5-coordination to indium but the 'centroid' indium vectors do not point toward the center of the hexaindium cluster as in other main-group clusters.
