When 2,3,5,6-tetrafluoro-4-(trifluoromethyl)phenylacetate (Tfpha) or 3,5-dinitrobenzoate (Dnb) anions were used instead of pentafluorobenzoate, mixed-anion compounds [Cd₂(Phen)₂(Tfpha)₂(Bz)₂] (<b>I</b>), [Cd₃(Phen)₂(Dnb)₃(Bz)₃][Cd₃(Phen)₂(Dnb)_4.5(Bz)_1.5] (<b>II</b>), [Zn₃(Phen)₂(Dnb)₄(Bz)₂]·2(C₆H₆) (<b>III</b>), and [ZnCd₂(Phen)₂(Dnb)₅(Bz)]·3(C₆H₆)·(MeOH) (<b>IV</b>) were isolated.
