ILLUSTRATIVE FRAGMENT ARRANGEMENT — relative positions are not structural data

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 (ETKDGv3 conformer generation, MMFF94 force-field optimisation; lowest-energy converged conformer of a fixed-seed set). 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.

This substance consists of 2 separate components (for example ions). Each component was computed separately; they are arranged radially around a layout anchor for visualisation only (at least 3.0 Å apart). Their relative positions are not a crystal structure, coordination geometry, ionic contacts or any experimentally determined arrangement.
