Monometallic lanthanide complexes

Application of the model-free methods to axial monometallic lanthanide complexes with sterically rigid ligands... 

In the case of the porous [R(phos)3] 2H20 networks, the adsorption isotherms have been recorded to test the intake capacity for N2, H2O, MeOH, and EtOH, of which 1.1,1.76, 0.8, and 0 molecule(s) per formula unit can enter into the pores of the material, respectively. The network is stable to several dehydration/hydration cycles, maintaining its homo-chiral structure (Yue et al., 2006). Another clever approach to porous materials able to host small molecules starts by producing a mixture of monometallic helical complexes with different chirality from lanthanide perchlorate and tris(2-benzimidazoylmethyl)amine L53 (Jiang et al.,... 

The size of the metal ion has an evident control on the synthesis of the monometallic macrocyclic complexes. For example, all lanthanide(III) ions promote the formation of the six-nitrogen-donor macrocycles with an 18-atom cavity and flexible aliphatic diimine side-chains, even though the yields become progressively lower as the metal atom size decreases. However, when the six-nitrogen, 18-atom macrocycles contain rigid o-phenylene side chains, the smaller lanthanides actually fail to promote... 

Lanthanide chemistry with Schiff bases is quite extensive and numerous acyclic, cyclic, monometallic and polymetallic (4f-4f, 4f-5f, 4f-nd) complexes have been synthesized and studied, in particular with compartmental ligands, owing to the ability of the latter to bind two or more metal ions in close proximity. Asymmetrization of these ligands also provides important diversification of the coordinating sites (Vigato and Tamburini, 2004). On the other...
