The utility of photochemical methods for the directed synthesis of mixed-metal metal clusters has been explored. The 366 nm photolysis of a solution containing [PPN] [Co(CO)4] (PPN = (Ph3P)2N+) and Os3(CO)12 gives the new cluster [PPN][CoOs3(CO)13] in 33% yield. Irradiation of a mixture of Fe(CO)5 and H2Os3(CO)10 yields H2FeOs3(CO)13 in 95% yield, and photolysis of Ru3(CO)12 in the presence of H2Os3(CO)10
已经探索了光化学方法在混合金属金属簇的定向合成中的实用性。包含[PPN] [Co(CO)4 ](PPN =(Ph 3 P)2 N +)和Os 3(CO)12的溶液的366 nm光解产生了新的簇[PPN] [CoOs 3(CO)13 ],收率33%。辐射Fe(CO)5和H 2 Os 3(CO)10的混合物可产生H 2 FeOs 3(CO)13,产率为95%,并在H存在下对Ru 3(CO)12进行光解2 Os 3(CO)10给出了新的簇H 2 RuOs 3(CO)13。讨论了这些合成的细节,其可能的机理以及新化合物的表征。
