Synthesis and structural characterization of lanthanum and cerium substituted cyclopentadienyl borohydride complexes

Molecular lanthanum and cerium borohydrides are utilized as precursors to a range of heteroleptic bulky substituted cyclopentadienyl complexes (carbon = gray, hydrogen = white, oxygen = red, boron = yellow, lanthanide = blue; only BH4 hydrogens are shown for clarity).151
