Synthesis, Characterization and Crystal and Molecular Structure of Tricyclopentadienylgallium(III).
Abstract
The new compound Ga(C5H5)3 has been prepared and fully characterized by elemental analyses, cryoscopic molecular weight measurements, IR and 1H NMR data, Lewis acid-base studies and an X-ray structural study. The new tricyclopentadienyl derivative is a colorless, volatile, pentane soluble, crystalline solid, which decomposes very slowly at room temperature and more rapidly at 45 deg C to form a yellow, pentane insoluble solid. An X-ray structural study of Ga(C5H5)3 demonstrates that the compound crystallizes in the monoclinic space group P2 sub 1/n with unit cell dimensions a = 10.904(8)A, b = 8.928(6)A, c = 13.533(8)A, beta = 92.19(5)A, and d sub calcd = 1.34 g/cc for Z = 4. Full-matrix least-squares refinement led to a final R value of 0.057 for 371 observed reflections. The crystal consists of discrete isolated molecules of Ga(C5H5)3, separated by normal van der Waals distances. There are no abnormally short intermolecular contacts.
