Abstract
Long-range interactions are found in a neutral sheetlike copper compound in which each CuII ion is bridged by alternating end-on and end-to-end azide groups (see picture). Magnetic studies show unusual ferromagnetic interactions between CuII ions through both kinds of azide bridges in this complex (order at Tc=7 K), which is the first two-dimensional metal-azide-bridged compound with long-range ferromagnetic ordering properties.
