Vibrational spectroscopy allows a reasonably unambiguous distinction to be made between monodentate, bidentate, and tridentate hydrogen-bridged metal-BH4 interactions for covalent organo-transition metal and -actinide tetrahydroborates. The following compounds have bidentate structures: (h5-C5H5)2Ti(BH4), (h5-C5H5)2Zr(BH4) 2, and (h5-C5H5)2Zr(H)(BH4); the organoactinides (h5-C5H5)3U(BH4) and (h5-C5H5)3Th(BH4) have tridentate geometries. Data on these systems can be understood in terms of analogies with other organometallic systems (π-allyls). The synthesis of (h5-C5H5)3Th(BH4) is also reported.
