“…[7] The first system of the α-M(fa) 2 series was manganese formate, which was first reported by Viertelhaus et al in 2003. [8] The following year, Kim and co-workers studied the porosity (adsorption of CO 2 , H 2 , and other gases) and commented on the material's potential use in gas separation, [9] while Wang, Kobayashi and co-workers investigated the magnetic properties. [10] Subsequently, the group of Wang published a series of further studies, reporting the structures, guest inclusion behaviour, and (where relevant) magnetic properties of Co(fa) 2 , [11] Zn(fa) 2 , [12] and Fe(fa) 2.…”
