Di-μ-chloro-dichlorobis(2,6-lutidine)diplatinum(II) dichloromethane solvate

Synthesis and structure of di-μ-hydroxo-bis[bis(dimethyl sulfoxide)platinum(II)] perchlorate

“…The O(1)-Pt-O(l') angle is reduced to 79.6 (4) ° while the Pt-O(1)-Pt angle is 100.4 (4) ° . These values are very close to those found in [Pt(NH3)2OH]22+ but are slightly different from those found in a Cl-bridged dimer where C1-Pt-CI' = 84.7 (1) and Pt-CI-Pt' = 95.3 (1) ° (Rochon & Melanson, 1981 (Melanson & Rochon, 1975, 1978a,b, 1984Melanson, Hubert & Rochon, 1976). The S atoms in the Me2SO molecules are in an approximate tetrahedral environment with angles ranging from 105.1 to 119.6 °.…”

Structural correlations for 1H, 13C and 15N NMR coordination shifts in Au(III), Pd(II) and Pt(II) chloride complexes with lutidines and collidine

“…These are probably rotational isomers, resulting from the restricted rotation around Pd-N or Pt-N bonds (due to the steric hindrance of ortho-positioned methyl substituents). This phenomenon was already noted for cis-[Pt(2,4lut) 2 Cl 2 ], [7] as well as for analogous Pd(II) and Pt(II) chloride complexes with 2-picoline (2pic): trans-[Pd(2pic) 2 4 ] 2+ . [7,13] [26] as well as for trans-/cis-[Pt(2pic) 2 I 2 ], [7] [Pd(2pic) 2 (phen)] 2+ , [27] [Pt(2pic) 2 …”

“…K 2 PdCl 4 was prepared from PdCl 2 and KCl; K 2 PtCl 4 by dissolving Pt in aqua regia, precipitation with KCl to K 2 PtCl 6 , and its reduction with hydrazine; NaAuCl 4 by dissolving Au in aqua regia, neutralisation with NaOH and evaporation to dryness.…”

Iodo-bridged complexes of platinum(II) and synthesis of cis mixed-amine platinum(II) compounds

“…Thus, the configuration of the dimer could not be determined although platinum(I1) dimers are very often centrosymmetric. The trans configuration is therefore expected as in the chloro-bridged dimer [Pt(2,6-lutidine)C1,I2 (7). We have tried to prepare adequate crystals for X-ray diffraction, in order to determine the crystal structure of one of the iodo-bridged dimers but have not been successful as yet.…”

“…Chloro-bridged dimers of piperidine, aniline, and pyridine derivatives have been reported (3)(4)(5)(6)(7). Courtot et al (5) synthesized a chloro-bridged dimer with a very bulky amine, t-butylamine but were unable to prepare dimers with smaller amines since their method of synthesis is limited.…”
