资源简介:

Pt2(μ-Se)2(PPh3)4 reacts with PtCl2(cod) to give {Pt2(μ3-Se)2(PPh3)4[Pt(cod)]}2+ and an unexpected cod-rich product that arises from metal scrambling, viz. {Pt(μ3-Se)2(PPh3)2[Pt(cod)]2}2+. The formation of these species was detected and followed by electrospray mass spectrometry (ESMS) and subsequently verified by batch synthesis and crystallographic characterization. Other metal-scrambled aggregate products were successfully detected.
