[3,3'-Bis(1-naphthylmethyl)-1,1'-(2,2'-oxy-diethyl-ene)bis-(imidazol-2-yl-idene)]mercury(II) bis-(hexa-fluorido-phosphate) acetonitrile solvate.

In the title compound, Hg(C(32)H(30)N(4)O)(2)·CH(3)CN, the mercury(II) ion is coordinated by two carbene C atoms [Hg-C = 2.060 (6) and 2.066 (6) Å] and one ether O atom [Hg-O = 2.561 (5) Å] in a distorted T-shaped geometry with a C-Hg-C angle of 166.3 (3)°. One hexa-fluorido-phosphate anion is rotationally disordered between two orientations with an approximate ratio of 2:1. The crystal packing exhibits weak inter-molecular C-H⋯F and C-H⋯N inter-actions.
