A three-dimensional accordion-like metal–organic framework: synthesis and unconventional oriented growth on a surface

We describe the synthesis and sorption properties of a new metal–organic framework (MOF), Fe(H2O)2(bpy)[Pt(CN)4]·H2O (bpy = 4,4′-bipyridine), with a three-dimensional accordion-like structure. Although crystalline oriented MOF thin films reported to date have been mainly limited to a layer-type structure, we succeeded in the fabrication of its crystalline oriented thin film.
