Abstract

Synopsis. Ligand field irradiation of cz-[CoCl₂{(CH₃)₂-PCH₂CH₂CH₂P(CH₃)₃}₂]+ in methanol and cis-[CoCl(H₂0)-{(CH₃)₂PCH₂CH₂P(CH₃)₂}₂]²⁺ in acetonitrile at 5°C led to isomerization to the trans isomer with quantum yields of 0.010 and 0.070, respectively. The same cis to trans photoisomerization of [CoCl₂(R₂PCH₂CH₂PR₂)₂]+ (R=CH₃, C₄H₉) occurred with much smaller quantum yields (ca.1X10^-4) and c-[CoCl₂{(C₆H₅)₂PCHCHP(C₆H₅)₂}₂]⁺ was reduced to cobalt(H) species on irradiation.
