几种多氮环合物的合成及质谱裂解

Synthesis and Composition in ESMS of Some Polyzia Complexes

用大环配体 L ( [( OPD) 2 ( DIEN ) 2 ] )与金属离子作用合成了 [Mn L ] ( Cl O4) 2 · 2 H2 O、[Co L ] Cl4·2 Me OH· H2 O、[Ni L ] ( Cl O4) 2 · 2 Me OH· 2 H2 O和 [Tb L ( Cl O4) 3 ( H2 O) 2 ]· 3 Me OH四种配合物 .用元素分析、红外光谱、摩尔电导对其组成和结构进行了鉴定 .并对其质谱裂解方式进行了讨论 .结果表明 ,过渡金属配合物在喷雾质谱条件下比较稳定 ,而稀土金属配合物在质谱条件下不太稳定 .

The four complexes of [MnL](ClO 4) 2·2H 2O, [CoL]Cl 4·2MeOH·H 2O, [NiL](ClO 4) 2 ·2MeOH·2H 2O and [TbL(ClO 4) 3(H 2O) 2]·3MeOH were synthesized by the reactions between macrocyclic ligand and metal ions. The compositions of the complexes were determined by elemental analysis and IR spectra. The decomposition processes of the complexes in ESMS condition were also discussed. The results show that transition metal complexes are stable and rare metal complex is not stable enough in ESMS condition.
