本文报导了二氯二乙烯—μμ′—二氯二铂络合物的质谱,并基于各种同位素组合的质量及其相对丰度的计算,对其质谱做了归属。该络合物在电子轰击下的碎裂行为,我们提出两个主要的碎裂历程:端基配位基C_2H_4和C1的竞争失去,形成一系列含有稳定的四元环结构单元(Pt_2C1_2)的碎片离子,以及端基配位基和桥联氯的逐步断裂,形成另一系列含有Pt—Pt键的碎片离子。 In this paper, the mass spectra of dichlorodi (ethylene) -μμ’-dichlorodi-platinum complexes were reported and their mass spectra were assigned based on the mass and relative abundance of various isotope combinations. The fragmentation behavior of the complex under electron bombardment, we propose two major fragmentation processes: loss of competition between terminal ligands C 2 H 4 and C 1 to form a series of complexes containing stable tetracyclic ring units (Pt 2 Cl 2) Fragments of ions, as well as the gradual breakdown of terminal ligands and bridging chlorine, form another series of fragment ions containing Pt-Pt bonds.
