==Preparation==
Ethenium has been observed in rarefied gases subjected to radiation.〔 Another preparation method is the reaction of certain proton donors such as , , , and with ethane at ambient temperature and pressures below 1 mmHg. (Other donors such as and will form ethanium preferably to ethenium.)〔
At room temperature and in a rarefied methane atmosphere, ethanium slowly dissociates to ethenium and . The reaction is much faster at 90 °C.〔
