Novel anionic metallacycles (6: [(1)
W(CO)4]; 7: ([(2) W(CO)4])2; 8: [(3) W(CO)4]; 9: [(4) W(CO)4]; and 10: [(5) W(CO)4]) were selectively
synthesized from the reaction of the flexible anionic pnictogenylborane
derivatives [M(C12H24O6)][H2E-BH2-EH2] [E = P, M = Na (1);
E = As, M = K (2)], [Na(C12H24O6)][H2As-BH2-PH2-BH2-AsH2] (3), and [Na(C12H24O6)(thf)2][tBuHE-BH2-EHtBu] [E = P (4); E = As (5)], with [W(CO)4(nbd)] (nbd =
bicyclo[2.2.1]hepta-2,5-diene). In addition, the reaction of 1, 4, and 5 with [Cu(MeCN)4][BF4] leads to unique coordination assemblies of the
general formula [Cu2Na2(RHE-BH2-EHR)4]n [E = P, R = H (11); E = P, R = tBu (12);
E = As, R = tBu (13)]. The
solid-state structure of compound 11 possesses an inorganic
3D scaffold with an adamantane-like repeating unit of Cu(I) ions.
新型阴离子金属环(6:[(1) 四羰基钨(W(CO)₄)];7:([(2) 四羰基钨(W(CO)₄)])₂;8:[(3) 四羰基钨(W(CO)₄)];9:[(4) 四羰基钨(W(CO)₄)];以及10:[(5) 四羰基钨(W(CO)₄)])可通过柔性阴离子氮族基硼烷衍生物与[四羰基钨(nbd)](nbd=双环[2.2.1]庚-2,5-二烯,即降冰片二烯,norbornadiene)的选择性反应合成。所涉柔性阴离子氮族基硼烷衍生物包括:[M(C₁₂H₂₄O₆,即18-冠-6)][H₂E-BH₂-EH₂](E=磷(P)、M=钠(Na)对应化合物1;E=砷(As)、M=钾(K)对应化合物2)、[Na(C₁₂H₂₄O₆,即18-冠-6)][H₂As-BH₂-PH₂-BH₂-AsH₂](化合物3),以及[Na(C₁₂H₂₄O₆,即18-冠-6)(四氢呋喃(thf))₂][tBuHE-BH₂-EHtBu](tBu为叔丁基(tert-butyl)、thf为四氢呋喃(tetrahydrofuran),E=磷(P)对应化合物4;E=砷(As)对应化合物5)。
此外,化合物1、4与5分别与[四乙腈合铜(I)四氟硼酸盐([Cu(MeCN)₄][BF₄]),其中MeCN为乙腈(acetonitrile)]反应,可得到通式为[Cu₂Na₂(RHE-BH₂-EHR)₄]ₙ的独特配位组装体,具体为:E=磷(P)、R=氢(H)对应化合物11;E=磷(P)、R=叔丁基(tBu)对应化合物12;E=砷(As)、R=叔丁基(tBu)对应化合物13。
化合物11的固态结构拥有无机三维骨架,其重复单元为类金刚烷型的一价铜(Cu(I))离子簇。
