methanol and resulted in complexes containing a 1:1 metal:ligand stoichiometry except in the cases of the cobaltcomplexes where a 1:2 metal:ligand stoichiometry was obtained. The 1 H NMR spectra of the zinccomplexes showed that the ligands containing the pendant arm in the 2-N position of the tetrazole ring bind the zinc ion more strongly than those containing the pendant arm in the 1-N position.
锌配合物的1 H NMR谱表明,在四唑环的2-N位上含有侧链的配体比在1-N位上含有侧链的配体更牢固地结合锌离子。还讨论了两种钴盐Co(L5A)2(NCS)2和Co(L5C)2(NCS)2的X射线结构。
