Rare-earth metal boroxides are not only rare and of great synthetic challenge but also
important theoretically due to their unrevealed bonding characteristics. In this paper, we …

The chemistry of transition metal complexes bearing boryl ligands (R2BÀ) has fascinated
scientists in organometallic and synthetic chemistry over the past two decades, because of …

Exploring new oxidation state of elements is an important and challenging issue. Rare‐earth
elements all exhibit the stable+ 3 oxidation state, while the+ 2 oxidation state is accessible …

alkyl or aryl) generallyexist as oligomers, both in solution and in the solid state1—a natural
consequence of the preference for high coordination numbers by the lanthanide metal ions …

A series of tris (oxoimidazolyl) hydroborato ligands, which serve as L2X [O3] donors, have
been employed to obtain organometallic zirconium compounds in an uncommon oxygen …

Oxalatoborates were transformed into dimeric spiro‐borate complexes by abstraction of
oxalate ligands by Lewis acidic lanthanide trichlorides. Oxalatoborates with different anions …

The treatment of diethylzinc with (9-BBN) 2O afforded a tetrameric species [(μ3-9-BBN-9-O)
ZnEt] 4 (1) in high yield due to the selective cleavage of metal− carbon bond whereas …

The d4 ML6 bis-boryl complex OsH (Bcat) 2Cl (PiPr3) 2 (Bcat= catecholborate) has been
prepared by the reaction of OsH2Cl2 (PiPr3) 2 with HBcat, via the monoboryl intermediate …

Low-coordinate first-row metal complexes of d0 [vanadium (V)], d1 [chromium (V)], and d2
[chromium (IV)] assume the unusual ligand field of a pseudotetrahedron when supported by …

We report the synthesis and reactivity studies of a pair of rhenium (V) oxo imido complexes.
Oxidation of the rhenium (III) terminal oxo ORe (η2-DHF)(BDI)(DHF= dihydrofulvalene, BDI …
