When isosteric molecules with non-isomorphous structures are combined into solid solutions they may arrange in yet another way: Despite their obvious similarity at the molecular level, 9,10-dichloro- and dibromo-anthracene differ clearly in their crystal structures. From these two components a solid solution with the latter compound as the minor constituent can be obtained as a phase pure product: it represents an entirely new structure type. |
