Heteroleptic cadmium(ii) and terbium(iii) pentafluorobenzoate-benzoate and pentafluorobenzoate-2-furancarboxylate compounds

Heteroleptic cadmium( ii ) carboxylates with anions of pentafluorobenzoic (pfb), benzoic (bz), and 2-furancarboxylic (fur) acids were prepared by the crystallization from aqueous solutions. The cadmium( ii ) pentafluorobenzoate-benzoate complex is structurally similar to the starting compound [Cd(pf...

Description
Summary:Heteroleptic cadmium( ii ) carboxylates with anions of pentafluorobenzoic (pfb), benzoic (bz), and 2-furancarboxylic (fur) acids were prepared by the crystallization from aqueous solutions. The cadmium( ii ) pentafluorobenzoate-benzoate complex is structurally similar to the starting compound [Cd(pfb)(H 2 O) 4 ] n • n (pfb): bz anions are involved in the cationic 1D polymer {[Cd(bz)(H 2 O) 3 ] n } n+ , whereas pfb anions are outer-sphere. The pentafluorobenzoate-2-furan-carboxylate compound [Cd(fur)(pfb)(H 2 O) 2 ] n • n (H 2 O) is a 1D coordination polymer. The heteroleptic Tb III complex [Tb 2 (bz) 2 (pfb) 4 (H 2 O) 2 (EtOH) 2 ]•2Hbz has a molecular structure. The supramolecular crystal structures of the new compounds are stabilized by non-covalent interactions.
