X-Ray Crystal Structure of Some New Alkoxycarbeneplatinum(II) Complexes

Dicyclometalated Mononuclear Bis(carbene)platinum(IV) Complexes

“…Figure depicts the ORTEP drawing, which reveals that 2 adopts an octahedral configuration of a central tetravalent platinum coordinated by two cis iodine atoms, two cis metalated carbons on the aromatic rings, and two trans (diamino)carbene ligands. The PtC bond distances (2.050(7) and 2.057(7) Å) are considerably longer than generally expected MC double bonds but normal for a trans Pt C bond, 2a,,10b, of which the longer Pt−C carbene bond is due to the delocalization of π-electrons over PtC(N<) 2 bonds, as frequently observed for the Fischer-type carbene complexes. The shorter bond distances (C(1)−N(1), 1.336 Å; C(1)−N(3), 1.315 Å) than normal C−N bond ones (ca.…”

Synthesis and Characterization of Platina-β-diketones

“…The Pt−Cl distances [ d (Pt−Cl) = 2.430(3) and d (Pt−Cl‘) = 2.430(4) Å] are in the range of those known for chloro-bridged platinum compounds. − The Pt−C distances [ d (Pt−C1)/ d (Pt−C3) = 1.95(1) Å] are equivalent within one esd. They are in the range of platinum carbene complexes, whereas the Pt−C bond distances in acylplatinum complexes are generally somewhat longer. − The C−O bond lengths [ d (C1−O1) = 1.26(1) Å and d (C3−O2) 1.23(1) Å] are equivalent within the 3σ limit. Thus the C−O bond lengths correspond to those in the rhena-β-diketone, cis -[Re{(COMe) 2 H}(CO) 4 ] ( 4 ) [1.28(2) and 1.25(2) Å, respectively] .…”

[Tc(NO)Cl(Cp)(PPh3)] – A Technetium(I) Compound with an Unexpected Synthetic Potential

“…The formation of Fischer‐type carbenes of the composition [Re(NO)(Cp)(PPh 3 ){C(OMe)R}] (R=Me, Ph) has been observed during reactions of acyl complexes with MeSO 3 F, [49] and also some analogous manganese complexes are known [50] . Additionally, there exist two related platinum compounds, which are formed from H 2 PtCl 6 , when it is treated with Me 3 SiCH 2 C≡CH or Me 3 SiC≡CH in iso‐propanol [51,52] …”
