Abstract

The silanedithiolato complex Pd(S2SiMe2)(PEt3)2 1 reacted with (C5H5)TiCl3 and TiCl4(thf)2 to produce the heterometallic clusters (C5H5)TiCl(mu-S)2Pd(PEt3)2 2 and TiCl2(S)(mu-S)2Pd2(PEt3)4 3 along with silicon-sulfur bond cleavage, respectively.

Coordination Chemistry of Silanedithiolato Ligands Derived from Cyclotrisilathiane: Synthesis and Structures of Complexes of Iron(II), Cobalt(II), Palladium(II), Copper(I), and Silver(I)

“…This leads to a remarkable increase in the stability of silanethiolato complexes. On the other hand, we found that these silanedithiolato complexes reacted with various metal chlorides and acetates under mild conditions. , For example, we previously reported that the reactions of 5 with (C 5 H 5 )TiCl 3 and TiCl 4 (thf) 2 afforded the copper−titanium sulfido clusters (C 5 H 5 ) 2 Ti 2 Cu 6 S 6 (PEt 3 ) 6 and ClTiCu 3 S 3 (PEt 3 ) 4 , respectively . The mixed-metal sulfido cluster synthesis based on complexes described here is the subject of ongoing work.…”

“…The chelating effect in coordination chemistry has most pronounced kinetic and thermodynamic consequences. This strategy could suppress the undesired degradation process of silanethiolato complexes via aggregation and/or ligand redistribution, while we found that chelating silanedithiolato complexes readily reacted with metal halides and acetates under mild conditions to produce mixed-metal sulfido clusters. , Here, we describe the detailed synthesis and structures of chelating silanedithiolato complexes of iron(II), cobalt(II), palladium(II), copper(I), and silver(I). In this paper, our aim is to demonstrate the versatility of silanedithiolates to act as chelating ligands toward a variety of metals from across the periodic table.…”

Zinc Chalcogenolate Complexes as Capping Agents in the Synthesis of Ternary II−II‘−VI Nanoclusters: Structure and Photophysical Properties of [(N,N‘-tmeda)5Zn5Cd11Se13(SePh)6(thf)2]

“…Single crystals were obtained from a 3:1 pentane:THF mixture upon cooling to −78 °C. M−ESiMe 3 complexes are rare, yet they are powerful synthons for the formation of M−E−M ‘ complexes, due to the preformed M−E bonds, and the existence of reactive pendant trimethylsilyl groups. The molecular structure (Figure ) confirms the presence of terminally coordinated SeSiMe 3 groups [Zn−Se = 2.3785(6), 2.3881(6) Å].…”
