摘要：

(2,3-Dimethylbutenyl)(pentamethylcyclopentadienyl)rhodium tetrafluoroborate, [Rh(C10H15)-(C6H11)][BF4], M(r) = 408.10, monoclinic, Cc, a = 8.418 (3), b = 14.185 (3), c = 14.840 (3) angstrom, beta = 91.98 (2)-degrees, V = 1771 (1) angstrom 3, Z = 4, D(x) = 1.531 g cm-3, mu-(Mo K-alpha) = 8.89 cm-1, lambda = 0.71073 angstrom, F(000) = 832, R = 0.032 for 3609 observed reflections. The compound has the typical appearance of a sandwich complex with two parallel pi-bonded ligands. An Rh...H...C bond to one of the methyl groups of the butenyl ligand is indicated by the bond parameters Rh...H = 1.88 (3), H-C = 1.12 (2) and Rh...C = 2.351 (5) angstrom, making this molecule a further typical example of an organometallic compound with an 'agostic' metal-to-hydrogen bond.
