{1,8-Bis[2-(1-benz­yl-1H-imidazol-3-ylmeth­yl-κC²)phen­oxy]-3,6-dioxaocta­ne-κ²O³,O⁶}mercury(II) bis­(hexa­flourophosphate) nitro­methane solvate

In the title compound, [Hg(C₄₀H₄₂N₄O₄)](PF₆)₂·CH₃NO₂, the geometry of the Hg coordination is distorted tetra­hedral, formed by two C atoms [Hg—C = 2.076 (7) and 2.068 (7) Å] and two O atoms [Hg—O = 2.703 (5) and 2.934 (5) Å]. The crystal packing is stabilized by weak C—H...F and C—H...O inter­actions.
