Popis: | The adducts of Co(II)(TPP) and Fe(II)TPP (TPP is meso-tetraphenyl-porphyrinato dianion) with carbon monoxide in Ar matrix at 10 K have been studied by FTIR spectroscopy using CO, C18O and their equimolar mixture. It is shown that both metals may form mono-carbonyl adducts with CO, however formation of bis-carbonyl adduct was confirmed only for iron porphyrin. These results refute an earlier assumption regarding existence of Co(TPP)(CO)2 in Ar matrix. |
