Abstract

Co(II)saloph (N, N-bis(salicylidene)-1,2-phenylenediamino-cobalt (II)) was encapsulated into VPI-5 and AlPO4-8. Aluminophosphate-hosted cobalt complexes were obtained by impregnating VPI-5 with Co(saloph). Co(saloph) encapsulated into AlPO4-8 was obtained by the structural transformation of VPI-5 occluding Co(saloph) into AlPO4-8. These complexes were characterized by XRD, and IR, 31P NMR and UV-VIS-NIR spectroscopy. The encapsulated complexes do not undergo any significant structural distortions in either case. As the amount of loaded Co(saloph) increases, five-coordinated complexes are formed in VPI-5, but not in AlPO4-8.

VPI-5和AlPO4-8包封Co(saloph)配合物的表征
将Co(II)saloph (N, N-二(水杨基)-1,2-苯二胺-钴(II))包封在VPI-5和AlPO4-8中。用钴(saloph)浸渍VPI-5得到了磷酸铝载钴配合物。通过VPI-5将Co(saloph)包封在AlPO4-8中的结构转化,得到了封装在AlPO4-8中的Co(saloph)。通过XRD、IR、31P NMR和UV-VIS-NIR光谱对这些配合物进行了表征。在任何一种情况下,包封的配合物都不会发生任何显著的结构扭曲。随着Co(saloph)负载量的增加,VPI-5中形成五配位配合物,而AlPO4-8中没有。
