The reactions of H 2 C[C(Me)N(C 6 H 3 ‐2, 6‐i‐Pr 2 )] 2 ((DPP) 2 NacNacH) and Zn(C 6 F 5 ) 2 · 2 EtCN or Cd(C 6 F 5 ) 2 · 2 MeCN in a molar ratio of approximately 1:1 selectively gave the derivatives (DPP) 2 NacNacMC 6 F 5 (M = Zn, Cd) in excellent yields. No reaction was observed between (DPP) 2 NacNacH and Hg(C 6 F 5 ) 2 under similar conditions. Reactions with Hg(C 6 F 5 )OCOMe yielded the products of dismutation, Hg(C 6 F 5 ) 2 and Hg(OCOMe) 2 . (DPP) 2 NacNacZnC 6 F 5 crystallises as a 1:1 adduct with THF with two independent molecules per unit cell (triclinic, P1 (no. 2)). The zinc atom is tetrahedrally surrounded by the chelating ligand, the pentafluorophenyl group and one THF molecule. A similar situation is found in the 1:1 adduct of (DPP) 2 NacNacCdC 6 F 5 and DMF (monoclinic, P2 1 /n (no. 14)), while in the donor‐free compound (CDCl 3 and H 2 O co‐crystallize) the cadmium atom is nearly ideally trigonal planar co‐ordinated (orthorhombic, Pbnm (no. 62)).
