英文摘要the mechanism of the synthesis of platinum carbonyl clusters pt-3(co)(6)](n)(2-) (n=3, 4) in cages of nay was studied by ir, exafs (co)-c-13 exchange reaction and no interaction. the results suggest that oxidized pt species in nay cages reacts with co at 304-373k to form pto(co) (sigma(co)-2110cm(-1)) which aggregates into "pt-3(co)(6)" (sigma(co)-2112, 1896 and. 1841cm(-1)) and eventually converts into dark-green carbonyl cluster (pt-12(co)(24)](2-). the carbonyl "pt-3(co)(6)" can exchange with (co)-c-13 very quickly at 298k init the exchange reaction between (co)-c-13 and intrazeolite pt carbonyl clusters [pt-3(co)(0)](n)(2-) (n=3, 4) proceeds slowly even, at enhanced temperature such as 343k. it is interesting to find that no breaks successively the intra and inter-trigonal lit lit bonds of the pt-12 carbonyl clusters (even at 298 k) and the "pt-3(co)(6)" formed is further reacted to give pto(co) with the formation of n2o and co2 in the gas phase. pt-2(co)(24)](2-) can be reversibly regenerated from the pt subcarbonyls such as pto(co) and "pt-3(co)(6)" inside nay by reacting wich co at 300-353k.
