In the title compound, [Cd(C2H8N2)3](GeF6), the CdII atom, lying on a 32 symmetry site, is coordinated by six N atoms from three ethylenediamine (en) ligands in a distorted octahedral geometry. The Ge atom also lies on a 32 symmetry site and is coordinated by six F atoms. The en ligand has a twofold rotation axis passing through the mid-point of the C—C bond. The F atom is disordered over two sites with equal occupancy factors. In the crystal, the [Cd(en)3]2+ cations and [GeF6]2− anions are connected through N—H⋯F hydrogen bonds, forming a three-dimensional supramolecular network.
