Metal-mediated transformation of a triazinephenanthridinium ligand leading to a {Pd5} coordination complex observed crystallographically and by cryospray mass spectrometry.

The formation of a pentanuclear palladium(II) complex with a phenanthridinonetriazine-based ligand system, which itself is formed by a metal-mediated rearrangement of a triazinephenanthridinium proligand, is described.
