Herein we describe the compatibility of 2‐(trifluoromethyl)‐2,3,3,3‐tetrafluoropropane nitrile, an insulating gas for gas‐insulated equipment, with aluminum, silver and copper. In an autoclave metal samples, oxygen, the gaseous 2‐(trifluoromethyl)‐2,3,3,3‐tetrafluoropropane nitrile and a small amount of water were mixed at elevated pressure and heated up to 225 °C for several weeks. When Cu was present a multi‐step gas phase reaction occurred, and single crystals of a copper complex were isolated. The square planar copper(II) complex contains two perfluorinated N ‐acylamidine ligands. The structure of the complex was obtained by single‐crystal X‐ray diffraction.
