Noble gases coordination geometry

In 1975, Perutz and Turner reported the first detailed and systematic matrix-isolation study 28) of noble gas coordination to transition metal centers in an investigation that followed the UV/visible photochemistry of M(C0)6 (M = Cr, Mo, and W) in noble gas, methane, and otiier matrices at 4 and 20 K. By comparing the IR spectra obtained with CO-enriched metal hexacarbonyls with the results of EFFF calculations 29), it was deiuonstrated that, upon short-wavelength UV photolysis of M(CO)e in the matrix, a molecule of CO was ejected and a M(CO)6 fragment with square-pyramidal (C4 ) geometry was produced.
