Mercury or silver atoms bridging trinuclear titanium imido–nitrido systems†
Abstract
The imido–nitrido complex [{Ti(η5-C5Me5)(μ-NH)}3(μ3-N)] entraps mercury(II) or silver(I) halides MXn to give cube-type adducts [XnM{(μ3-NH)3Ti3(η5-C5Me5)3(μ3-N)}] which react with alkali metal bis(trimethylsilyl)amide reagents to afford [M2{(μ3-N)n(μ3-NH)2−nTi3(η5-C5Me5)3(μ-NH)(μ3-N)}2] (M = Hg, n = 2; M = Ag, n = 1) where two [Ti3N4] cores are linked by two mercury or silver atoms in a linear geometry.
