We are employing bifluoride, HF2-, as a synthon in the self-assembly of magnetic coordination polymers of various dimensionalities, d, where d can be controlled using appropriate ancillary organic ligands. Two classes of materials have been produced which consist of quasi-2D networks held together via very strong hydrogen bonds. These new systems demonstrate interesting magnetic properties ranging from long-range antiferromagnetic ordering to weak ferromagnetism. Similar to cyanide, azide, and other small ligands, our work suggests that M-F···H···F-M and M-F···H-O-M bridges can be exploited in analogous fashion to produce a wealth of new magnetic coordination polymers. Highlights of this work will be presented.
