title: {3,3'-Bis[(anthracen-9-yl)meth-yl]-1,1'-[(ethane-1,2-diyldi-oxy)bis-(ethane-1,2-di-yl)]bis-(imidazol-2-yl-idene)}mercury(II) bis-(hexa-fluoridophosphate) acetonitrile disolvate.
abstract: In the title compound, [Hg(C(42)H(38)N(4)O(2))](PF(6))(2)·2CH(3)CN, the Hg(II) cation lies on a twofold axis which is also the inter-nal symmetry element of the complete cationic complex. The Hg(II) cation is coordinated by two symmetry-related C(carbene) atoms [Hg-C = 2.058 (9) Å] in a nearly linear geometry, with a C-Hg-C angle of 175.8 (5)°. There are weak inter-molecular C-H⋯F inter-actions in the crystal packing between an F atom of a hexa-fluoridophosphate anion and a -CH(2)- group of the bis-N-heterocyclic carbene ligand.
