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)
