Direction of topological isomers of silver(I) coordination polymers induced by solvent, and selective anionexchange of a class of PtS-type host frameworks

The construction of two types of coordination polymers with closely related 4-connected topologies [PtS and lvt (4^2.8^4)] were achieved based on a well-designed bent dipyrazine linker, and the topological differences only result from the stereochemistry of silver(I) coordination sphere with the same coordination donors. Selective anion-exchange functions of the series of PtS-type coordination networks containing different counter anions (from small BF4^- to very large SbF6^-) were identified.
