摘要: Abstract The compounds [Ni(L)(H-chdc−)2] (1) (L = C-meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane; H2-chdc = 1,4-cyclohexanedicarboxylic acid) and [Ni(L)(H2-btc−)2]·2H2O (2) (H3-btc = 1,3,5-benzenetricarboxylic have been synthesized structurally characterized. crystal structure of 1 shows a distorted octahedral coordination geometry around the nickel(II) ion, with four secondary amines two oxygen atoms H-chdc− ligand at trans position. In 2, ion is depicted as octahedron in 2D hydrogen-bonded infinite chain. electronic spectra complexes are significantly affected by nature carboxylate ligands. cyclic voltammogram undergoes one-electron wave corresponding to NiII/NiI process.
