n~5-环戊二烯基三羰基铬钠与甲基氯化汞在二缩乙二醇二甲醚中室温反应12h,得产率为58％的双(n~5-环戊二烯基三羰基铬)汞.经碳氢分析、IR、~1H NMR、MS及单晶X光衍射技术证实.晶体属空间群P2_1/c..晶胞参数:α=8.023(2),6=20.843(9),c=10.331(2);β=96.00(3)°; Z=4.Cr—Hg平均键长为2.655.汞与2个铬原子近于共线.每个铬原子可看作是处于以环戊二烯基为底的五角锥和以3个羰基、1个汞原子为底的四角锥的公共顶点上。
n ~ 5-cyclopentadienyl tricarbonyl chromium sodium and methyl mercuric chloride in ethylene glycol dimethyl ether at room temperature for 12h, yield 58% of bis (n ~ 5-cyclopentadiene The results showed that the crystal space group P2_1 / c .. unit cell parameters: α = 8.023 (2), 6 = 20.843 (9), c = 10.331 (2); β = 96.00 (3) °; Z = 4. The average bond length of Cr-Hg is 2.655. Mercury is nearly collinear with two chromium atoms. It is on the common pentagonal pentacyclic cone at the base of the cyclopentadienyl group and the pyramid at the base of the three carbonyl and one mercury atom.
