A layered magnet is formed from the reaction (see H‐tube apparatus; bottom) of tetracyanoethylene (TCNE; left) and [Fe(CO) 5 ] (right). The structural elucidation described by P. W. Stephens, J. S. Miller, and co‐workers in their Communication on page 1521 ff. reveals that magnetic layers of [TCNE] .− bonded to four high‐spin Fe II ions are connected by [C 4 (CN) 8 ] 2− , the diamagnetic σ dimer of [TCNE] .− , which explains the higher than expected magnetization for this ferrimagnet.
