The thermal behaviour of ternary Co(II), Ni(II) and Cu(II) complexes with phthalate ion and 1,10-phenanthroline or 2,2'-dipyridylamine
摘要:
The synthesis, spectroscopic and structural characteristics, as well as the thermal behaviour, of a series of Co(II), Ni(II) and Cu(II) complexes with the phthalate ion and 1,10-phenanthroline or 2,2'-dipyridylamine are presented. Thermal stability increases in the order Cu < Ni < Co for the 1,10-phenanthroline complexes, and Ni < Cu < Co for the 2,2'-dipyridylamine complexes. The relationship between the thermal properties of the complexes and their crystal structures, their polymeric nature, and the presence or absence of water of crystallization is discussed.
