A simple thermodynamic model for rationalizing the formation of self-assembled multimetallic edifices: Application to triple-stranded helicates
Reaction of the bis-tridentate ligand bis{1-ethyl-2-[6?-(N,N- diethylcarbamoyl)pyridin-2?-yl]benzimidazol-5-yl}methane (L2) with Ln(CF3SO3)3¡¤xH2O in acetonitrile (Ln = La-Lu) demonstrates the successive formation of three stable complexes [Ln(L2)3]3+, [Ln2(L2) 3]6+, and [Ln2(L2)2]6+. Crystal-field independent NMR methods establish that the crystal structure of [Tb2(L2)3]6+ is a satisfying model for the helical structure observed in solution. This allows the qualitative and quantitative (beta23bi,Ln1Ln2) characterization of the heterobimetallic helicates [(Ln1)(Ln2)(L2) 3]6+. A simple free energy thermodynamic model based on (i) an absolute affinity for each nine-coordinate lanthanide occupying a terminal N6O3 site and (ii) a single intermetallic interaction between two adjacent metal ions in the complexes (DeltaE) successfully models the experimental macroscopic constants and allows the rational molecular programming of the extended trimetallic homologues [Ln 3(L5)3]9+.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 52093-25-1, you can also check out more blogs about52093-25-1
