Photolyse von in einer Ar Matrix bei 20 K isoliertem Cr(CO)5(CSe)Durch UV-Photolyse von Cr(CO)5(CSe), das in einer Ar-Matrix bei etwa 20 K isoliert wurde, entstehen zwei isomere Formen von Cr(CO)4(CSe) und Cr(CO)6 sowie CO (zu weiteren Details vgl. Abstract).
Notes:
U. v. photolysis (254 and 366 nm) of Cr(CO)5(CSe) isolated in an argon matrix at ca. 20 K produces a mixture of two isomeric forms of Cr(CO)4(CSe), Cr(CO)6 and molecular CO. The two Cr(CO)4(CSe) isomers are assigned square pyramidal geometries (CSe group axial, C4v symmetry; CSe group equatorial, Cs symmetry) by comparison with the results from a previous matrix isolation i.r. study of the products formed in the u.v. photolysis of the analogous thiocarbonyl complex, Cr(CO)5(CS). On further irradiation of the Cr(CO)4(CSe) species with visible light (λ 〉 425 nm), the parent Cr(CO)5(CSe) molecule is regenerated.
