Zn(GlySer)₂ Metal Organic Framework

ZnGlySer is a peptide-based metal organic framework (MOF) with the chemical formula [Zn(GlySer)₂]. It is made up of tetrahedral Zn²⁺ each coordinated by four glycine–serine dipeptide . There are (green dashed lines) between the dipeptide’s side chain and the guest molecules (MeOH). This is a two-dimensional (2D) layered MOF with between peptides in neighbouring layers. This MOF is flexible and the pores close when the solvent is removed. (see animation)
