  Abstract

[2(L)(N3n(2O2] [이 경우, M = U22+, T4+, ZrO2+; 단, U22+ 및 ZrO2+의 경우 n = 2; Th4+의 경우 n = 6], [(VO2(L)(S4)(2O)], [L = 1,15-di(o-hydroxyphenyl)-2,3,6,7,9,10,13,14-octaaza-4,5,11,12-tetraphenyl/tetramethylpentadeca- 1,3,5,10,12,14-hexa-ene-8-thione (opt2/omt2)] 형태의 일련의 동종이핵착물을 thiocarbohydrazide, benzilmonohydrazone/diacetylmonohydrazone 및 salicylaldehyd로부터 주형법에 의해 합성한 후, 원소분석, 열분석, 몰 전기전도도, 자기모멘트, UV, IR 및 1H NMR 실험으로부터 그 특성을 조사하였다. 이 결과로부터 U22+ 및 ZrO2+ 이 온은 육배위 그리고 Th4+ 이온은 팔배위의 반자기성 착물을 형성하는 반면, VO2+의 경우 위의 조성을 갖는 오배위의 상자기성 착물을 형성하는 것이 확인되었다. A series of homobinuclear complexes of the type [2(L)(N3n(2O2], [where M=U22+, Th4+, ZrO2+, n=2 for U22+, ZrO2+, n=6 for Th4+] and [(VO2(L)(S4)(2O)], L=1,15-di(o-hydroxyphenyl)-2,3,6,7,9,10,13,14-octaaza-4,5,11,12-tetraphenyl/tetramethyl-pentadeca-1,3,5,10,12,14-hexa-ene-8-thione (opt2/omt2) have been synthesized in template method from thiocarbohydrazide, benzilmonohydrazone/diacetylmonohydrazone, salicylaldehyde and characterized on the basis of elemental analysis, thermal analysis, molar conductivity, magnetic moment, UV, IR and 1H NMR studies. The results indicate that U22+ and ZrO2+ ions are hexa-coordinated; Th4+ ion is octa-coordinated yielding diamagnetic complexes whereas the VO2+ ion is penta-coordinated yielding paramagnetic complexes of above composition.
