Abstract

The imido-nitrido complex [{Ti(eta(5)-C(5)Me(5))(mu-NH)}(3)(mu(3)-N)] entraps mercury(ii) or silver(i) halides MX(n) to give cube-type adducts [X(n)M{(mu(3)-NH)(3)Ti(3)(eta(5)-C(5)Me(5))(3)(mu(3)-N)}] which react with alkali metal bis(trimethylsilyl)amide reagents to afford [M(2){(mu(3)-N)(n)(mu(3)-NH)(2-n)Ti(3)(eta(5)-C(5)Me(5))(3)(mu-NH)(mu(3)-N)}(2)] (M = Hg, n = 2; M = Ag, n = 1) where two [Ti(3)N(4)] cores are linked by two mercury or silver atoms in a linear geometry.

摘要

亚氨基-氮化物配合物[{Ti(η⁵-C₅Me₅)(μ-NH)}₃(μ₃-N)]捕获汞(II)或银(I)卤化物MXₙ，生成立方体型加合物[XₙM{(μ₃-NH)₃Ti₃(η⁵-C₅Me₅)₃(μ₃-N)}]，该加合物与碱金属双(三甲基硅基)酰胺试剂反应，得到[M₂{(μ₃-N)ₙ(μ₃-NH)₂₋ₙTi₃(η⁵-C₅Me₅)₃(μ-NH)(μ₃-N)}₂]（M = Hg，n = 2；M = Ag，n = 1），其中两个[Ti₃N₄]核通过两个汞或银原子以线性几何构型相连。
