Bis(1-benzyl-3-methyl-imidazolium-κC)mercury(II) bis-(hexa-fluoridophosphate).

The asymmetric unit of the title complex, Hg(C(11)H(12)N(2))(2)(2), consists of one bis-(1-benzyl-3-methyl-imidazolium)mercury(II) cation, one half of the cation and an additional Hg(II) atom, which lies on an inversion centre, and three hexa-fluorido-phosphate anions. The Hg(II) atoms exist in a linear coordination geometry [C-Hg-C = 178.9 (2) and 180°] formed by two carbene C atoms from the imidazole rings. In the crystal, the cations and anions are connected via C-H⋯F hydrogen bonds, forming a three-dimensional network.
