Abstract While magnesium hydride complexes are generally stabilized by hard, bulky N‐donor ligands, softer ligands with a broad variety of coordination modes are shown to efficiently adapt themselves to the large variety of Mg 2+ centers in a growing magnesium hydride cluster. A P,N‐chelating ligand is introduced that displays coordination modes between that of enamide, aza‐allyl, and phosphinomethanide. Slight changes in the ligand bite angle have dramatic consequences for the structure type. The hitherto largest neutral magnesium hydride clusters are isolated either in a nonanuclear sheet‐structure (brucite‐type) or a dodecanuclear ring structure.
