desorption/ionization mass spectra of the benzene complex Cr(CO)3(C6H6) and the [2.2]cyclophane complexes Cr(CO)3(C16H16-1,4), Cr(CO)3(C16H16-1,3), and Cr(CO)3}2(C24H24) are reported. In each spectrum intense ion signals are obtained which correspond to the decarbonylated chromium arene cation [Cr(arene)]+ and the bis(arene) sandwich cation [Cr(arene)2]+. The cyclophane complexes also generate ion signals at higher
苯配合物Cr(CO)3(C 6 H 6)和[2.2]环烷配合物Cr(CO)3(C 16 H 16 -1,4),Cr的正离子紫外激光解吸/电离质谱报告了(CO)3(C 16 H 16 -1,3)和Cr(CO)3 } 2(C 24 H 24)。在每个光谱中,获得对应于脱羰基铬芳烃阳离子[Cr(arene)] +和双(芳烃)夹心阳离子[Cr(arene)2 ] +的强离子信号。环烷配合物还产生更高质量的离子信号,这可归因于扩展的多核夹心复合物。另外,Cr(CO)6和[2.2]对环环烷的混合物的紫外激光解吸质谱显示包含含有新的金属-配体键的离子,即。夹心物质[Cr(C 16 H 16 -1,4)2 ] +。
