In recent work [1] we published that the combination of bisphosphonate linker (phenylene-1,4-bis(methyl-phosphinic acid)) and Fe³⁺ or Al³⁺ salts form highly stable MOF structures. When we replaced alkyl group on phosphorus or prolonged the linker, isoreticural structures with similar stability were prepared [2]. In this work we replaced phoshinate group by phosphonate, which again led to isoreticural structures.
