Formation and Characterization of Platinum and Palladium Complexes of Bis(trimethylsilylmethyl)tellane

Abstract

The mononuclear (telluroether)platinum and -palladium complexes cis- [ ] (3t) have been prepared from bis(trimethylsilylmethyl)tellane and bis(benzonitrile)dichloridoplatinum and -palladium and structurally characterized by single-crystal X-ray diffraction and NMR spectroscopy. The isomer distribution of the platinum complex depends on the initial molar ratio of the reactants. When [PtCl 2 (NCPh) 2 ] was used in excess, 2c was the main product. Upon increasing the initial ligand/metal molar ratio, the relative amount of 2t increased. The stoichiometric reaction afforded approximately equal amounts of the cis and trans isomers. Further increase of the initial amount of the ligand yielded 2t. The mononuclear palladium complex was

Preparation and structural characterization of [RuCl2(CO)2{Te(CH2SiMe3)2}2] and [RuCl2(CO){Te(CH2SiMe3)2}3]

“…As we have observed that the Te(CH 2 SiMe 3 ) 2 ligand leads to interesting stereochemical features in case of palladium(II) and platinum(II) centers [11], it was decided to utilize this ligand also in exploration of coordination chemistry of ruthenium(II) complexes. In this work, we report the synthesis and structural characterization of [RuCl 2 (CO) 2 …”

Formation and structural characterization of mercury complexes from Te(R)CH2SiMe3 (R = Ph, CH2SiMe3) and HgCl2

“…[10]). It is interesting to note that the 125 Te resonances of both 3b and 4b are found upfield from those of 3a and 4a (see Fig.…”

“…It has recently been reported that the palladium(II), platinum(II) [9][10][11], rhodium [12], and ruthenium(II) [13] complexes containing the Te(CH 2 SiMe 3 ) 2 (1) [9] ligand show interesting stereochemical features. In this contribution we explored the ligand properties of 1 and related unsymmetric Te(Ph)(CH 2 SiMe 3 ) 2 (2) towards the mercury(II) center.…”

“…The respective spectral widths were 24.04, 126.58, and 100.00 kHz. The pulse widths were 11.00, 10.00, and 19.5 ls, respectively. 13 Hg accumulations contained ca.…”

Versatile coordination chemistry of rhodium complexes containing the bis(trimethylsilylmethyl)tellane ligand

“…Bis(trimethylsilylmethyl)tellane ligand forms complexes with palladium(II), platinum(II), and ruthenium(II) centres that exhibit interesting stereochemical features [14][15][16]. In this paper, we are concerned with the reaction of Te(CH 2 SiMe 3 ) 2 and RhCl 3 Á 3H 2 O.…”
