Ligand properties of organic selenium and tellurium compounds

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

“…6 that this resonance is found in the region of mononuclear complexes. The presence of both the mer-and fac-isomers in solution has been reported for [RhCl 3 It can also be deduced from Fig. 6 that the resonance at 294 ppm is due to a tellane ligand in a mononuclear complex.…”

“…The Rh-S bond lengths span a range of 2.3561 (6) 3 ], respectively. The trans-influence of chlorine and sulfur seems to be of comparable strength with possibly that solid mixture that upon crystal structure determination turned out to be mer-[RhCl 3 {Te(CH 2 SiMe 3 ) 2 } 2 (SMePh)] Á ½CH 3 CH 2 OH (5 Á ½EtOH) with the two tellane ligands in trans-positions with respect to each other.…”

“…[1][2][3][4][5]). One of the first examples was the reported synthesis of [RhCl 3 (TePh 2 ) 3 ] from RhCl 3 and diphenyl telluride [6], but no structural information was given.…”

Tetraphenylphosphonium salts of 2-telluro-5-methylthiophene and its mercury(II) metal complex

“…The chemistry of organoselenium and organotellurium compounds, on the other hand, is much less developed (Gysling, 1986). The anion, 2-tellurothiophene, one of the few stable organotellurides (Engman & Cava, 1982), has been used to prepare one of only two known homoleptic metal organotelluride complexes, a tetrameric silver cluster, Aga(TeCaH3S) 2- (Zhao, Adcock, Pennington & Kolis, 1990).…”

Structure of trans-diiodobis(methyl phenyl telluride)platinum(II)

“…Introduction. The coordination chemistry of Te donor ligands has only recently attracted serious study (Gysling, 1982(Gysling, , 1986. In a detailed study * Author to whom correspondence should be addressed.…”
