The two-dimensional antiferromagnet [Cu(HF2)2(pyz)]n (pyz=pyrazine) has a rectangular lattice (see picture) displaying two types of FHF− bridging modes. The spin exchange through Cu-(FHF)2-Cu is about 90 % stronger than through Cu-pyz-Cu, and the μ1,1-coordinated FHF−, which is close in nature to F−⋅⋅⋅HF, is largely responsible for the exchange.
