The magnetic polymer is produced when copper ions bind to pyrazine molecules creating a sheet-like structure, shown in the blue-purple crystals. Like a Tinkertoy ® building block, the bifluoride ion, shown in green, acts as a bridge to hold the planes together. The product is a three-dimensional coordination polymer, held together by one of the strongest hydrogen bonds known, making this a very thermally stable material. Credit: Argonne National Laboratory

Researchers at the U.S. Department of Energy's Argonne National Laboratory have pioneered a new approach for making magnetic polymers that are held together with very strong hydrogen bonds. These polymers contain an innovative bifluoride, HF2–, building block that allows a magnetically ordered state to be obtained. The development may help lead to new techniques for faster and more versatile computer chips, among other applications.
