Hague, R.H. Prince Title: Electronic spectra of organometallic compounds. Part I. Phenyl compounds of group IV containing a chromophoric metal-metal linkage Journal/Source: J. Chem. Soc., 4690-4696, (1965); DOI: 10.1039/JR9650004690 Data: table, diagram Energy/Wavelength range: 225 - 285 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: solution (cyclohexane) pH: Comments: The ultraviolet absorption spectra in solution of several organometallic compounds of Group IV elements of the general type R6M2, have been recorded. An absorption band at about 245 nm with molar extinction coefficient in excess of 30000 is found in addition to a strong band with maximum below 220 nm. lambda(max) = 246.5 nm (epsilon = 32600; oscillator strength = 0.611) Author to whom correspondence should be addressed: (e-mail address):
