incompletely characterised oil. The binuclear, crystalline zirconium(IV) amides [Zr(NMe2)3}2(μ-D′)] 4, its D analogue 5 and [Zr(NMe2)2}2(μ-D)2] 6 were prepared from [Zr(NMe2)3(μ-NMe2)}2] and H2(D′) [or 2 H2(D′)], H2(D) and 2 H2(D), respectively. The single crystal X-ray molecular structures of complexes 3 and 4 have been elucidated. That of 3 comprises a sixteen-membered, twisted macrocyclic LiNC5NLiNC5N
