The solid-state structure and Raman spectrum of Wannagat's mercurane, Hg[N(SiMe3)(2)](2) ( 1), are reported. Crystals were grown from the pure substance by slow cooling to -24 degrees C. Compound 1 crystallizes in the monoclinic space group P2(1)/c as discrete monomers, which do not display intermolecular mercurophilic interactions. The molecular structure features a nearly linear N-Hg-N scaffold, while the (Me3Si)(2)N groups are in a staggered conformation with a dihedral angle of 58.3 degrees (average) to each other. This can be attributed to intramolecular dispersion interactions according to DFT calculations.
