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.
