quantities of trans-TeF4(N3)2 and fac-TeF3(N3)3. A 1 : 2 reaction initially led to all members of the series except mer-TeF3(N3)3, with TeF5(N3) and trans-TeF4(N3)2 gradually disappearing. An unidentified tellurium(IV) species appeared in both of the azide reactions and often obscured the signal due to cis-TeF2(N3)4. With azide ion, TeF6 gave [TeF5]–, [TeF7]– and nitrogen.
通过19 F NMR光谱已经确定,TeF 6和Me 3 SiX(X = N 3或NMe 2)反应形成化合物TeF n X 6 – n(n = 1-5)。TeF 6与Me 3 SiNMe 2以1:2的比例反应,得到TeF 5(NMe 2),顺式-TeF 4(NMe 2)2和fac -TeF 3(NMe 2)3的混合物。TeF 4为1:4得到(NMe 2)2(两种异构体),TeF 2(NMe 2)4(两种异构体)和TeF(NMe 2)5。TeF 6与Me 3 SiN 3以1:1的比例反应,以TeF 5(N 3)和cis -TeF 4(N 3)2为主要成分,微量的反式-TeF 4(N 3)2和fac -TeF 3(N 3)3。最初的1:2反应导致除mer -TeF 3(N 3) 3以外的所有成员,而TeF 5(N 3)和反式-TeF 4(N 3) 2逐渐消失。在两个叠氮化物反应中均出现未知的碲(
