No source 3-D conformer was available to MolGod for this substance. MolGod Scientific computed this geometry from the structural formula with RDKit 2026.03.6 (no conformer embedding or force-field optimisation was needed: the substance consists of single-atom ions only, whose arrangement is a presentation convention). It is not a measured structure, it does not come from PubChem, and it has not been compared with experimental data. It shows one possible conformation.
