Fe13 Iron-pseudocarbyne (IMAGE) Arizona State University Caption Iron pseudocarbynes are likely widespread in the interstellar medium, where extremely cold temperatures would lead carbon chains to condense on the Fe clusters. Over eons, complex organic molecules would to emerge from these Fe pseudocarbynes. The model shows a hydrogen-capped carbon chain attached to an Fe13 cluster (iron atoms are reddish brown, carbon is gray, hydrogen is light gray). Credit P.
