Coordination polymers and metal-organic frameworks built up with poly(tetrazolate) ligands

In the past two decades the chemistry of coordination polymers (CPs) and metal-organic frameworks (MOFs) has known an incessant development at both the academic and industrial level: the diversity they show in chemical composition, structural features and chemico-physical properties makes them attractive for a wide range of applications of technological, economical and/or environmental interest. Within this scenario, this review focuses the attention on the transition-metal-ion CPs and MOFs built up with bis-, tris- and tetrakis(5-substituted tetrazolate) ligands. After a short introduction on CPs and MOFs, and the chemistry of tetrazole and its derivatives, the reader is provided with a brief description of the synthesis, structural aspects and, whenever studied, functional properties of the numerous transition metal poly(5-substituted tetrazolate) frameworks appeared in the literature to the end of 2017.
