The crystal structure for MnCl2 tetrahydrate formula should be MnCl2(H2O)4
Instead, it’s shown as MnH8(ClO2)2
Hi @KingRaychard - the formulas on MP are automatically generated and may not always use the same chemical ordering convention you are used to. The important thing is the formulas are identical in atom count
If you’d like to contribute to how formulas get ordered by convention, please submit a PR to pymatgen-core
