The synthesis and characterization of µ-hydrido-bis-(µ-sulphide)-ditungsten(III) complexes: the X-ray crystal structure of [HPPh3][Cl3W(µ-H)(µ-Me2S)2WCl3]
Abstract
The reaction of WCl4(Me2S)2 with Et3SiH yields Cl3W(µ-H)(µ-Me2S)2WCl2(Me2S) from which the anion [Cl3W(µ-H)(µ-Me2S)2WCl3]– can be prepared; a single-crystal X-ray diffraction study of [HPPh3][Cl3W(µ-H)-(µ-Me2S)2WCl3] shows that these complexes possess a confacial bioctahedral framework with a formal W–W triple bond of length 2·410(7)Å.
