diethylene-triamine, Hpico = picolinic acid, tn = 1,3-propanediamine, H2aeida = aminoethyliminodiacetic acid, H2apida = aminopropyliminodiacetic acid, H2eddp = ethylenediamine-N,N′-dipropionic acid, H2ox = oxalic acid and H3nta = nitrilotriacetic acid. The geometric structures of these complexes were assigned on the basis of UV-vis, proton NMR and fluorine NMR spectra. All these complexes show a pH-dependent
新准备了15个标题复合体。省略结晶水,它们是:[Co(hfac)L] ClO 4,其中L = fac(N)-(β-ala)(bpy),fac(N)-(1-ala)(bpy),fac(N)-(gly)(bpy),mer(N)-(gly)(en),mer-(NO 2)(dien),mer(N)-(pico)(en),mer(N) -(pico)(tn); [CO(HFAC)L],其中L =顺式(O)-aeida,反式(O)-aeida,顺式(O)-apida,β-EDDP,C 2 -顺式(O)-Gly)2,顺式- (氧)(NH 3)2,(ox)(en); 和K [Co(hfac)(nta)],其中hfac充当双齿,L是占据剩余四个配位点的配体的混合物。配体的缩写为:Hhfac =六氟-2,4-戊二酮,H(β-ala)=β-丙氨酸,bpy = 2,2'-联吡啶,H(l-ala)= 1-丙氨酸,Hgly
