| Abstract : Perpustakaan Tuanku Bainun |
| Ligan-ligan terbitan-terbitan berfluorin 1-fenil-3-metil-4-benzoil-5-pirazolona (HPMBP), 1-fenil-3-metil-4-(2-fluorobenzoil)-5-pirazolona(HPMoFBP),1-fenil-3-metil-4-(3- fluorobenzoil)-5-pirazolona(HPMmFBP) dan1 -fenil-3-metil-4-(4-fluorobenzoil)-5- pirazolona (HPMpFBP) telah disediakan bagi tujuan mengkaji kestabilan komplekskompleks La(III), Pr(III), Eu(III), Ga(III), Er(III) dan Lu(III). Didapati pemalar kestabilan untuk semua kompleks adalah mengikut turutan: La(III) < Pr(III) < Gd(III) < Eu (III) < Lu(III) < Er(III). Dapatan ini sepadan dengan pemecahan orbital f apabila komplekskompleks ini terbentuk.
Kata kunci Pemalar kestabilan kompleks-kompleks lantanida, terbitan berfluorin 5-pirazolona. |
