“…[25,26] In the presence of bulkier ligands, more acute oxo bridge angles have been reported. [27] The formation of the dimer demonstrates how air/moisture sensitive this system is and how any form of oxygen can stabilise the product.…”

“…Hydrolysis usually completely decomposes the complexes, but traces of water can generate oxidobridged species, for example [Cl 3 (Me 2 S) 2 Ti(µ-O)Ti (Me 2 S) 2 Cl 3 ]. 42 The prospect of using simple TiX 4 -chalcogenoether complexes as single source precursors for low pressure chemical vapour deposition (LPCVD) of layered TiE 2 films, has resulted in detailed re-examination of some of these simple complexes. The [TiCl 4 (L) 2 ] (L = Me 2 S, tht or cyclo-(CH 2 ) 5 S) were made from TiCl 4 and the thioethers in hexane, and the structure of cis-[TiCl 4 (tht) 2 ] determined.…”

Developments in the chemistry of the hard early metals (Groups 1–6) with thioether, selenoether and telluroether ligands

The coordination chemistry of neutral thio-, seleno-and telluroether ligands towards the hard s-block, f-block and higher oxidation state early d-block metals has developed significantly over the 15 or so years. This has revealed several hitherto unknown classes of complexes and new insights into the chemistries of these hard-soft metal-ligand combinations. This Perspective describes the synthetic routes used to access such complexes and draws out their key structural features and spectroscopic properties. Where appropriate, applications of these species are also highlighted, including their use as single source precursors for the chemical vapour deposition of semiconducting metal chalcogenide thin films and as pre-catalysts for olefin polymerisation reactions. IntroductionThioether and selenoether ligands, which are neutral sulfur and selenium donors respectively, were for many years viewed as modest σ-donor ligands that formed complexes with the softer later d-block elements in low or medium oxidation states, or with post transition metals such as silver or mercury.1,2Complexes of the early d-block metals were mostly limited to low valent organometallics or carbonyls. The chemistry of telluroethers was very little explored, in major part a reflection of their limited availability and, for the alkyl telluroethers in particular, their extremely malodorous nature. 2,3The R2Te ligands are also oxygen sensitive (in contrast to the air stable R2S or R2Se), modest reducing agents and prone to cleavage of the CTe bond upon reaction with some metal centres. Even today, their chemistry remains much less extensive than that of their lighter analogues. 4 Major developments in the syntheses and coordination chemistry of macrocyclic thioethers considerably extended the range and stability of complexes containing metal centres across the d-block. More recent work has resulted in complexes of chalcogenoethers with many of the p-block elements,

“…However, µ-oxo homodinuclear titanium species with Ti-O-Ti bond angles slightly less than 180° appear to be more common. (Honzíček et al, 2004;Levason et al, 2003;Mahrwald et al, 2001;Schormann, 2003) In addition to the bridging oxygen in I, there is one diethylamido (N2) and one diethylamino (N1) group, as well as two chlorides (Cl1 and Cl2) coordinated to the titanium. Each titanium atom is best viewed as having distorted square pyramidal coordination geometry as judged by the τ-descriptor (Addison et al, 1984) which is 0.13 for this molecule.…”
