Infrared spectroscopic studies reveal that u.v. irradiation of 6-C7H8)(CO)3> (1) in CH4 and Ar matrices at 12 K results in the reversible formation of 6-C7H8)(CO)2> via photodissociation of CO.Energy-factored force field fittings show that the species 6-C7H8)(CO)(3-n)(13CO)n)> (n = 1-3) and 6-C7H8)(CO)(2-m)(13CO)m> (m = 0-2) are produced on prolonged irradiation of (1) in a 13CO doped (5percent) CH4 matrix at 12 K.Photolysis of (1) in a N2 matrix at 12 K leads to photoproducts of the type 6-C7H8)(CO)(3-x)(N2)x> (x = 1-3).Stepwise photoelimination of cycloheptatriene in a CO matrix at 12 K results in the conversion of (1) to via the intermediate species 4-C7H8)(CO)4>.
Excited state properties of the (tropylium)molybdenum tricarbonyl cation

The electronic spectrum of [(η-C7H7)Mo0(CO)3]+ shows its longest-wavelength absorption at λmax = 379 nm which is assigned to a Mo0 → η-C7H7+ MLCT transition; the 3MLCT excited state is luminescent at room temperature; solid [(η-C7H7)Mo0(CO)3]PF6 as well as solutions of the complex in MeCN display this emission at λmax ca. 580 nm; the MLCT state is also reactive; in EtOH solutions [(η-C7H7)Mo0(CO)3]+ is reduced to [(η-C7H8)Mo0(CO)3] with φ = 0.18 at λirr = 366 nm.
