Breaking up isn't hard to do: When a solution of the hydride complex [K(dme)]2[{Nb}2(μ‐H)4] (see scheme) is exposed to N2, the nitride complex [K(thf)2]2[{Nb}2(μ‐N)2] and H2 form with concomitant cleavage of the dinitrogen triple bond. The nitride ligands undergo alkylation with MeI in a stepwise fashion, resulting in formation of a bis(imide) complex via a nitride imide complex.

A hydroxo-or carboxylate-bridged dinuclear Ni(II) complexes with N,N,NA,NA-tetrakis{(6-methyl-2-pyridyl)me-thyl}-1,3-diaminopropan-2-ol has been synthesized as models for Ni(II)-substituted phosphotriesterase, which are more active catalysts for hydrolysis of phosphodiester than the corresponding dinuclear Cu(II) and Zn(II) complexes.

Tri(2-oxy-3,5-di-tert-butylphenyl)methane, [O3]3- has been used to prepare titanium and zirconium complexes of the general formula [O3]MX (M = Ti, X = NEt2, Cl, CH2Ph; M = Zr, X = CH2Ph). The tripodal [O3] ligand in titanium complexes adopt the syn- and the anti-conformation, while the syn complex of zirconium undergoes facile C-H activation to give a 5-carbametalatrane [O3C]Zr(THF)3.
