 abstract = {Five new lanthanide(III) sandwich and half-sandwich complexes with bulky cyclooctatetraenyl ligands have been prepared and fully characterized, including single-crystal X-ray structure determination. The treatment of anhydrous lanthanide(III) chlorides, LnCl3 (Ln = Pr, Tb, Yb), with 2 equivalents of Li2COT$\prime$$\prime$ [COT$\prime$$\prime$ = 1,4-bis(trimethylsilyl)cyclooctatetraene dianion] followed by crystallization in the presence of a coordinating solvent afforded the anionic sandwich complexes [Li(THF)4][Pr(COT$\prime$$\prime$)2](1), [Li(DME)3][Tb(COT$\prime$$\prime$)2](2; DME = 1,2dimethoxyethane), and [Li(TMEDA)2][Yb(COT$\prime$$\prime$)2](3; TMEDA = N,N,N$\prime$,N$\prime$-tetramethylethylenediamine). Attempted oxidation of

 2 with silver iodide did not afford the neutral terbium(IV) sandwich complex [Tb(COT$\prime$$\prime$)2]. Instead, the tri(\textgreek{m}-iodido)-bridged dinuclear half-sandwich complex [Li(DME)2][Tb2(\textgreek{m}-I)3(COT$\prime$$\prime$)2](4) was isolated in 72 {\%} yield. In this complex, the Li(DME)2 fragment is attached to one of the \textgreek{m}-iodido ligands. A closely related binuclear lutetium complex, [Li(DME)3][Lu2(\textgreek{m}-Cl)3-(COTbig)2]·DME (5), was obtained by using the {\grqq}superbulky{\grqq} COTbig ligand [COTbig = 1,4-bis(triphenylsilyl)cyclooctatetraenyl dianion]. In addition to the spectroscopic and structural characterization, the magnetic properties of the paramagnetic terbium(III) derivative 2 have been investigated and further complemented by ab initio computational methods. These results have been used to discuss the structural requirements for potential terbium(III) single-ion magnets.},
