Solvent-free synthesis of new metal sulfate–oxalates containing chain-like building blocks

•New metal sulfate–oxalates were prepared under solvent-free conditions•Possible build-up processes for different hybrid frameworks were proposed•Metal sulfate–oxalates display hcb, mog, and kgd topologies

Four new metal sulfate–oxalates were synthesized under solvent-free conditions. These compounds have single-layered, double-layered, and three-dimensional structures containing metal oxalate chains as building blocks. Topological analyses reveal that they have hcb, mog, and kgd topologies, respectively. Possible build-up processes for the formation of the hybrid frameworks were proposed.
