Synthesis and X‐ray Structural Characterization of the Polymeric Cluster Compound [Hg₃(O₂SePh)(SePh)₅]_n

Abstract

Two synthetic routes to prepare [Hg 3 (O 2 SePh)(SePh) 5 ] n and its structural characterization are presented in this paper. This compound results either from the partial oxidation of mercury phenylselenolate clusters or from a mixture of its components with defined stoi-* Prof. Dr. E. S.

This compound was observed in almost all of our reactions as a by-product, during the development of the synthesis of new mercury selenolate clusters. It was now characterized by single-crystal Xray diffractometry, elemental analysis, and infrared spectroscopy.

“…49 Heterobimetallic clusters [Hg(m-EPh) 2 {Cu(PPh 3 ) 2 } 2 ] and [Hg(EPh)(m-EPh)(m-Cl)Ag(PPh 3 ) 2 ] (E = S, Se) have been prepared from [Hg(EPh) 2 ] and [Cu/Ag(PPh 3 ) 2 ] + , 37 while the trimercuric cluster [Hg 3 (O 2 SePh)-(SePh) 5 ] n is obtained by reaction of Hg(SePh) 2 with either O 2 or PhSeO 2 H; the authors thus account for its prevalence as a by-product in reactions of Hg(SePh) 2 . 50 A series of complexes based on 1,3-bis(aryl)triazenide ligands have been prepared and characterised, illustrating prevalent Hg-p interactions in the extended structures. 51,52 Finally, the new ternary halide Hg 2 BrI 3 has been reported, and is considered a candidate for developing infrared NLO materials.…”
