Chemical Structure from Scientific Research

The frameworks of IWV and CTH are highly related and both can be constructed by ton , non and d 4 r building units in a very similar manner. The very similar IWV and CTH layers, which are also closely related to those of TON and NON (Supplementary Fig. 16 ), are built from ton units. The incorporation of non units to the IWV and CTH layers results in the IWV _1 layer and CTH _1 layer, respectively. The neighbouring IWV _1 layers and CTH _1 layers are then connected by sharing d 4 r units to form the IWV and CTH frameworks, respectively. Only one type of the ordered CTH framework is presented here. Oxygen atoms have been omitted from the structures for clarify.
