The molecular structures of (RF)2Zn (3), (RF)2Cd(MeCN) (4a), and (RF)2Hg (5) have been determined by X-ray crystallography (RF = 2,4,6-tris(trifluoromethyl)phenyl). For 3: triclinic, P1, a = 8.339 (3) ?, b = 9.064 (2) ?, c = 13.499 (4) ?, α = 88.38 (3)°, β = 87.79 (4)°, γ = 76.85 (2)°, V = 992.6 (5) ?3, Z = 2, and R = 3.92%. For 4a: monoclinic, P21/c, a = 10.876 (3) ?, b = 16.79 (1) ?, c = 13.865 (5) ?, β = 112.81 (2)° V = 2334 (2) ?3, Z = 4, and R = 3.49%. For 5: monoclinic, P21/n, a = 8.842 (2) ?, b = 7.891 (2) ?, c = 15.294 (3) ?, β = 92.20 (3)°, V = 1066.3 (4) ?3, Z = 2, and R = 5.73%. A characteristic structural feature of all three derivatives is weak metal-fluorine interactions. (RF)2Zn and (Rf)2Cd(MeCN) represent the first examples of structurally characterized two- and three-coordinate monomeric diarylzinc and -cadmium compounds, respectively.
