A novel ferrocenyl dimer [Zn2(μ-OOCFc)4(3-PyCOOCH3)2] (Fc=(η5-C5H5)Fe(η5-C5H4)), 1, was obtained by the reaction of Zn(OAc)2·2H2O with sodium ferrocenecarboxylate and 1,4-butanediol dinicotinate in methanol solution. X-ray structural analysis reveals that the compound contains two zinc(II) centers symmetrically bridged by four ferrocenecarboxylate anions as O,O'-bridging ligands, leading to a dimeric tetrabridged [Zn2(μ-OOCFc)4] core. The zinc(II) ion is in a distorted octahedral environment with four oxygen atoms from four distinct ferrocenecarboxylates, a nitrogen atom from the ligand NC5H4CO2CH3, and another zinc atom. The symmetry of the complex in the paddle-wheel structure brings the metal centers close, the intradimer distance being 2.934(11) Å. It is the first example of a zinc(II) dimer with ferrocenecarboxylate anion ligands. Its thermal properties were measured in air. |
