Recent work in our group has focused on the use of s-block aryloxide aggregates as secondary building units in the assembly of extended network polymers. We found that by varying the nature of the substituted aryloxide we could predictably control the structure of the resulting extended networks. We then wished to add another level of sophistication by controlling the number of metal atoms within each aggregate that could act as a point of extension. To achieve this aim, we synthesized a series of mixed-anion aggregates through the addition of alkoxides with chelating amine sidearms to our lithium aryloxide systems. By blocking one or more of the lithium sites, we can achieve greater control over the dimensionality of the resulting framework. A series of crystal structures will be presented that demonstrate the utility of this strategy in the rational design of network topologies.
