Abstract:Di‐ and multinuclear hafnium complexes bridged by ligands have been rarely reported. In this article, a novel 3,5‐disubstituted pyrazolate‐bridged ligand LH5 with two [N2N]2−‐type chelating side arms was designed and synthesized, which supported a series of dinuclear hafnium complexes. Dinuclear hafnium azides [LHf2(μ‐1,1‐N3)2(N3)2][Na(THF)4] 3 and [LHf2(μ‐1,1‐N3)2(N3)2][Na(2,2,2‐Kryptofix)] 4 were further synthesized and structurally characterized, featuring two sets of terminal and bridging azido ligands lik… Show more
