Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Whilst both geometries are possible (and indeed observed, IF 5 is square pyramidal), I suspect that your confusion arises from the fact that iron pentacarbonyl is able to undergo a phenomenon known as Berry psuedorotation. Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around a central atom, of a molecule from an examination of the number of bonds and lone electron pairs in its Lewis structure. So its structure will be a trigonal planer structure.
