Trialkylboron/lanthanide metallocene hydride chemistry: Polydentate bridging of (HBEt3)(-) to lanthanum
The reaction of [(C5Me5)(2)LaH](x) with BEt3 is reported, and the solid-state structures of the lanthanum product (C5Me5)(2)La[mu-H)(mu-Et)(2)BEt], 1, and its THIF adduct (C5Me5)(2)La(THF)[(mu-H)(mu-Et)BEt2], 2, are compared with that of the hydride-bridged "tuckover" complex (C5Me5)(2)La(mu-H)(mu-eta(1) : eta(5)-CH2C5Me4)La(C5Me5), 3.
