muf-7a Growing beautiful crystals like these is one of the joys of doing chemistry. These perfect specimens take the shape of a truncated rhombic dodecahedron. They are from a class of materials known as metal-organic frameworks, and they spontaneously grow from zinc metal ions and organic ligands. Although imperceptible at this scale, X-ray crystallography shows us that they have a sponge-like structure with large pores and voids. In fact, the internal surface area of a gram of these crystals is equivalent to an entire football field! These materials are being investigated for their ability to store gases such as hydrogen for powering next-generation vehicles. These photos were taken with a conventional optical microscope.
