Synthesis and structure of 1,3-bis[tris(trimethylsilyl)methyl]-2,4,5-triselena-1,3-digermabicyclo[1.1.1] pentane
Abstract
1,3-Bis[tris(trimethylsilyl)methyl]-2,4,5-triselena-1,3-digermabicyclo[1.1.1]pentane 4, obtained by photodeselenation of the corresponding 2,4,5,6-tetraselena-1,3-digermabicyclo[2.1.1]hexane, shows a short Ge ⋯ Ge distance of 2.672 Å; an Se ⋯ Se interaction in 4 is observed by 77Se NMR, X-ray analysis and electronic spectroscopy.
