Solid state coordination chemistry of metal-1,2,4-triazolates and the related metal-4-pyridyltetrazolates

This short review focuses on the structural chemistry of the coordination polymers of 1,2,4-triazole (Htrz) and the 1,2,4-triazolate ligand (trz) and of 4-pyridyltetrazolate (pt) which can be considered as an expanded analogue of 1,2,4-triazolate. The structures are discussed in terms of some common building blocks and the sorptive and magnetic properties of these materials.
