Application of 1271-48-3, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde,introducing its new discovery.
Ferrocene-based compartmental ligand for the assembly of neutral Zn II/LnIII heterometallic complexes
A ferrocene-based compartmental ligand, H2L, was synthesized by the reaction of diacetyl ferrocene with hydrazine hydrate followed by a condensation reaction with o-vanillin. [L]2- possesses a dual coordination pocket, an inner pocket of 2 imino nitrogens and two phenolate oxygens and an outer pocket of two phenolate and two methoxy oxygen atoms. Utilizing this ligand, several ZnII/LnIII heterobimetallic complexes were assembled: [LZn(mu-OAc)Dy(NO3)2] (2), [LZn(mu-OAc)Tb(NO3)2] (3), [LZn(mu-OAc)Gd(NO 3)2¡¤2CHCl3] (4), [LZn(mu-OAc) Er(NO3)2] (5), [LZn(mu-OAc)Ho(NO3) 2] (6), [LZn(mu-OAc)Eu(NO3)2] (7). All of these metal complexes are neutral and isostructural: the ZnII ion occupies the inner coordination pocket while the LnIII ion occupies the outer coordination pocket of the doubly deprotonated ligand [L] 2-. Zn(ii) has a coordination number of 5 (2N, 3O) in a square pyramidal coordination geometry while Ln(iii) has a coordination number of 9 (9O) in a distorted tricapped trigonal prismatic geometry. Zn(ii) and the 4f metal ion are bridged to each other by two phenolate oxygen atoms and an acetate ligand. ESI-MS reveals that 2-7 retain their structural integrity in solution. Cyclic voltammetry of 1-7 revealed a quasi-reversible oxidation (involving the ferrocene motif) and an irreversible reduction of the hydrazone unit. Magnetic studies of 2, 3 and 6 were carried out. Ac susceptibility studies did not reveal slow relaxation of magnetization.
