Abstract

Reaction of neodymium iodide-hydride NdI2H with CpK in THF affords organoneodymium hydride [K(THF)2][(η5-C5H5)3Nd(μ-H)Nd(η5-C5H5)3] (1). Dysprosium analog DyI2H under the same conditions yields the known complex Cp3Dy(THF). The reaction of NdI2H with potassium phenoxide in THF affords the ionic cluster [K(THF)2][Nd3(PhO)10(THF)4] (2). In each case, interaction is accompanied by dihydrogen evolution. The molecular structures of 1 and 2 have been defined by X-ray diffraction analysis. The interaction of NdI2H with CpNa or CpLi gives an intractable mixture of products. The compounds PhC≡CK, NaN(SiMe3)2, KN(SiMe3)2, K(), and C5Me5K are inert toward NdI2H.
