Solvent-free synthesis of new metal phosphate–oxalates: influence of different metal ions on the framework structures†
Abstract
A series of new metal phosphate–oxalates were synthesized under solvent-free conditions. These compounds display interesting open-framework structures with mmt, ins, fsd, and hcb topologies, respectively. The extra-large 20-ring channel, nanobelt-like inorganic skeleton, and the use of cadmium ions as framework cations are unprecedented in metal phosphate–oxalate structures.
