Mercury forms a wide range of alloys (amalgams), some of which are known from ancient times. Square‐planar Hg 4 6− units are known to be particularly favorable building blocks in many amalgams. It is reported here that the unusual Hg 4 6− square is aromatic (the picture shows the HOMO−1 (1a 2u ) molecular orbital), analogous to the recently discovered all‐metal Al 4 2− ion.
