The reaction of 1-(4-ethoxycarbonylphenyl)-3-(2-fluorophenyl)triazene with mercury(II) acetate in the presence of potassium methanolate in methanol yields [Hg(RNNNR′)2] [R = 4-C2H5OC(O)C6H4, R′ = 2-FC6H4] as light-yellow crystals. [Hg(RNNNR′)2] complex molecules are associated to [Hg(RNNNR′)2]2 dimeric units through centrosymmetric metal-η2-arene π-interactions. The dimeric units – related to each
