Structures of Metallocarboranes. V. Synthesis and Crystal and Molecular Structure of the CLOSO- 20-Electron Bimetallocarborane 1,6-Bis(eta-Cyclopentadienyl)-1,6-diferra-2,3-dicarba-CLOSO-decaborane(8), 1,6-(eta-C5H5)2-1,6,2,3-Fe2C2B6H8.
Abstract
The polyhedral expansion of 4,5-C2B7H9 with ferrous chloride and sodium cyclopentadienide produced a new ferracarborane formulated as (C5H5)2-Fe2C2B6H8, which exists in paramagentic and diamagnetic forms. The crystal and molecular structure of the diamagnetic form has been determined by a three-dimensional x-ray diffraction study at - 160C. The compound crystallized in the monoclinic centrosymmetric space group P2(1)/n. The polyhedral geometry observed in this compound is a new 10-vertex species which is derived from a bicapped square antiprism. Structures of the title compound and of its cobalt analog are discussed in terms of the bonding theory of metallocarboranes.
