There is no firm evidence that any first row transition element dihalides are non‐linear. This conclusion is drawn from the fact the IR bands previously assigned to “non‐linear” LiF 2 definitely arise from trigonal planar TiF 3 . Earlier matrix isolation studies, from which a 120°‐TiF 2 had been concluded, formed the cornerstone of the theory of anomalous MF 2 molecules.
