Synthesis and structure of a polynuclear complex with a framework consisting of germanium, bismuth and platinum atoms

(Ge4Bi14)4−: A Case of “Element Segregation” on the Molecular Level

“…These values align well with corresponding bond lengths of 2.463(2) and 2.461(3) Å in the straight‐chain oligogermane Ge 4 Ph 10 , with the external bond being only 0.04 Å longer in 1 . The Bi−Ge1 bond lengths in 1 (2.6621(14) and 2.6785(13) Å) are smaller than those in the few comparable compounds, [Ph 2 Bi−Ge 9 −BiPh 2 ] 2− (2.733(1) Å), [(C 6 F 5 ) 2 Ge] 3 Bi 2 (2.739(7) Å), and (Ge 8 Bi) 2 4− (2.922(13) Å) . The Bi−Ge2 bond lengths (2.7985(12) and 2.8290(12) Å), however, are more in line with these values.…”

“…[5] TheGe 4 chain in 1 has an internal Ge1ÀGe1' bond length of 2.453 (3) and an external Ge1ÀGe2 bond length of 2.5045 (17) .These values align well with corresponding bond lengths of 2.463(2) and 2.461(3) in the straight-chain oligogermane Ge 4 Ph 10 , with the external bond being only 0.04 longer in 1. [13] The Bi À Ge1 bond lengths in 1 (2.6621(14) and 2.6785 (13) )a re smaller than those in the few comparable compounds, [Ph 2 BiÀGe 9 ÀBiPh 2 ] 2À (2.733 (1) ), [29] [(C 6 F 5 ) 2 Ge] 3 Bi 2 (2.739- (7) ), [30] and (Ge 8 Bi) 2 4À (2.922 (13) ).…”

Trimetallic ReBiPt complexes containing spiro-bismuth ligands from the reaction of the bis(tri-t-butylphosphine)platinum with Re3(CO)12(μ-BiPh2)(μ-H)2

“…As expected, the PteBi distance for the smaller platinum atom is significantly shorter, Pt (1)eBi(1) ¼ 2.6355(6) Å. The only previously reported characterization of a platinumebismuth bonding interaction was for the compound, Pt(PPh 3 ) 2 Bi 2 [Ge(C 6 F 5 ) 2 ] 3 , 16, PteBi ¼ 2.759(3) Å[19]. The longer length of the PteBi distance in 16 may be due to the presence of the two bulky PPh 3 ligands that are coordinated to the platinum atom.…”

Synthesis, structure and reactivity of complexes containing a transition metal–bismuth bond

“…Razuvaev and co-workers reported the solid state synthesis of [(C 6 F 5 ) 2 Ge] 3 Bi 2 by the reaction of [(C 6 F 5 ) 2 GeH 2 ] with BiEt 3 at high temperature [188,189]. Treatment of this ring structure with zerovalent platinum or palladium species [M(PPh 3 ) 3 ] (M = Pd, Pt) in benzene resulted in the insertion of the transition metal into one of the Ge-Bi bonds.…”
