Reaction of (CO)6Fe2(μ-Se)2 with HCCCCR (R Sime3 or SnnBu3) at room temperature in methanol containing sodium acetate yielded the unexpected product (CO)6Fe2Se2}2(μ-s-trans-C4H2) in which a 1,3-butadiene ligand is coordinated to Fe2Se2 core in a trans conformation as determined by a single-crystal X-ray diffraction studies. The complex was also obtained with a low yield by reaction of (CO)6Fe2(μ-Se)2
(CO)6 Fe 2(μ-Se)2与HCCCCR(RSime 3或Sn n Bu 3)在室温下在含
乙酸钠的
甲醇中反应生成未预期的产物(CO)6 Fe 2 Se 2 } 2(μ-s-反式-C 4 H 2),其中
1,3-丁二烯配体与反式构象的Fe 2 Se 2核配位,这是通过单晶X射线衍射研究确定的。通过(CO)6 Fe的反应也以低收率获得了该络合物。在类似条件下用HCCCconditionsCH 2(μ-Se)2。
