The reactions of Zn(OAc)2·2H2O with various positional isomers of lutidine were explored with a view to understand the factors responsible for the nuclearity/aggregation and acetate coordination modes of the products. The reactions of Zn(OAc)2-2H2O with 3,5-lutldine, 2,3-lutidlne, 2,4-lutidine, and 3,4-lutidine in a 1:1 ratio in methanol at ambient temperature afforded three discrete trlnuclear complexes [Zn 3(OAc)2(mu2-eta2: eta1-OAc)2(mu2 eta1 :eta1-OAc)2(H2O)2(3,5lutidine) 2] (1), [Zn3(mu2-eta1 :eta1-OAC)4(mu2-eta2: eta0-OAC)2L2] [L = 2,3-lutidine (2) and 2,4-lutidine (3)], and a onedimensional coordination polymer [Zn(OAc)(mu2 eta1:eta1-OAc)(3,4-lutidine) ] (4) in 93, 79, 81, and 94% yields, respectively. Complexes 1-4 were characterized by microanalytical, IR, solution (1H and 13C), and solid-state cross-polarization magic angle spinning 13C NMR spectroscopic techniques and single-crystal X-ray diffraction data. Complex 1 is unique In that it contains three types of acetate coordination modes, namely, monodentate, bridging bidentate, and asymmetric chelating bridging. Variable-temperature 1H NMR data indicated that complex 1 partially dissociates In solution, and the remaining undissociated 1 undergoes a rapid “carboxylate shift” even at 218 K. The plausible mechanism of formation of complexes 1 -4 was explained with the aid of a point zero charge (pzc) model, according to which the nuclearity/aggregation observed In complexes 1-4 depends upon the number and nature of equilibrating species formed upon dissolution of the reactants In methanol, and these In turn depend upon the subtle basic/steric properties of lutidines. Further, noncovalent Interactions play a crucial role In determining the nuclearity/ aggregation and acetate coordination modes of the products.
Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant. I hope my blog about 108-47-4 is helpful to your research. Related Products of 108-47-4
