摘要：

The crystal and molecular structure of pentamethylcyclopentadienyl Grignard reagent has been determined by X-ray diffraction in the monoclinic space group C2/c; cell parameters a 21.51(2) angstrom, b 11.778(6) angstrom, c 14.04(1) angstrom, alpha 90-degrees, gamma 90-degrees, beta 95.17(7)-degrees, V 3543(5) angstrom-3, Z = 4 dimers, with R = 0.1047, R(w) = 0.0938, R(G) = 0.1068. The pentamethylcyclopentadienyl Grignard reagent is a dimer in which chloro ligands bridge two Mg2+ ions which are each coordinated to a eta-5-Cp-star group and a THF molecule. A disorder toluene molecule is also found in the crystal lattice.
