Strong through-space two-halide magnetic exchange of -234 K in (2,5-dimethylpyrazine)copper(II) bromide.
An unprecedented antiferromagnetic exchange of -234 K in Cu(2,5-dimethylpyrazine)Br(2) is shown experimentally and theoretically to propagate via through-space interactions between Br ions rather than through-bond interactions.
