Synthesis, characterisation and reactivity of a zinc triazenide for potential use in vapour deposition

• In this study, we synthesised and characterised a new zinc(ii) triazenide for potential use in vapour deposition of zinc sulphide thin films. The compound is volatile and quantitatively sublimes at 80 degrees C under vacuum (0.5 mbar). Thermogravimetric analysis showed a one-step volatilisation with an onset temperature at similar to 125 degrees C and 5% residual mass. The compound also reacted with 2 or 4 molar equivalents of triphenylsilanethiol to give dimeric and monomeric zinc thiolates, respectively. The high volatility, thermal stability, and reactivity with sterically hindered thiols makes this compound a potential candidate for use in vapour deposition of zinc containing thin films. Herein, we synthesise and characterise a new volatile and thermally stable Zn(ii) triazenide. We also react it with a bulky thiol to give two different Zn(ii) thiolates. This new triazenide shows high promise as a precursor for vapour deposition of ZnS thin films.
