50_07b/2011Back Cover: [Cu(HF2)2(pyrazine)]n: A Rectangular Antiferromagnetic Lattice with a Spin Exchange Path Made Up of Two Different FHF Bridges (Angew. Chem. Int. Ed. 7/2011)

Two types of HF2 bridges are found in the rectangular polymeric network formed from CuII, FHF, and pyrazine (pyz). The resulting linear Cu-(FHF)2-Cu chains are linked into 2D sheets by pyz units. The FHF coordination in the Cu-(FHF)2-Cu chains mimics motifs found in transition metal/azide systems. In their Communication on page 1573 ff. J. L. Manson et al. also show that stronger spin exchange occurs along the HF2 bridges than the Cu-pyz-Cu bridges.
