Synthesis and structure of a compound with an ytterbiumtin bond, (Ph3Sn)2Yb(THF)4

Mono‐ and Dinuclear Heteroleptic Cobalt Complexes with α‐Diimine and Polyarene Ligands

“…These bond lengths are very close to those of the neutral naphthalene ligand in the anionic complex [(η 5 ‐Cp)V(C 10 H 8 )] − 15. 16 In comparison, the CC bond lengths of the coordinated arene unit in complexes that contain a dianionic naphthalene ligand, such as [CpV(C 10 H 8 )VCp],18 [CpLu(C 10 H 8 )(DME)],19 [(μ 2 ‐η 4 :η 4 ‐C 10 H 8 ){LaI 2 (THF) 3 } 2 ],20 and [Tm(DME) 2 (C 10 H 8 ) 3 ],21 show obvious long–short–long character. The naphthalene ligand in 3 is slightly bent, as in the anthracene ligand of complex 2 , with a fold angle of 14.0° at the central carbon atoms (C59 and C61) of the coordinating ring.…”

f‐Element–Metal Bonding and the Use of the Bond Polarity To Build Molecular Intermetalloids

“…Shortly after the report by Bochkarev et al.,46, 47 Cloke, Lawless and co‐workers52 presented the somewhat similar ytterbium–tin complex [(thf) 2 Yb{Sn(CH 2 t Bu) 3 } 2 ] ( C5 , Figure 3) with an Yb–Sn bond length of 321.6(1) pm. In contrast to the above‐mentioned studies, salt elimination was employed as the synthetic concept in this work.…”

“…The first structurally authenticated complex with Ln-MM bonds was published in 1990 by Bochkarev et al, [46,47] it has the constitution [(thf) 4 Figure 3) and features a Yb-Sn bond length of 330.5(1) pm. The coordination sphere of ytterbium is distorted octahedral with the stannyl ligands arranged trans to each other.…”

f-Element silicon and heavy tetrel chemistry

“…) 89. The mechanism of formation of 51 was proposed by the authors to proceed by a 2 electron transfer from [Yb(C 10 H 8 )(THF) 2 ], generating neutral C 10 H 8 and reductively cleaving one C Ph -Sn bond, formally resulting in {Ph 3 Sn} and {Ph} anions and a solvated Yb(II) cation.…”
