characterized by 1H NMR in solution. The molecular structure of metallodendrimers G0 and G1 [Ni(NO3)2(Gn-dend)CH(3,5-Me2pz)2}] have been determined by X-ray diffraction methods. Both structures show an almost identical three-dimensional organization of the –ArCH2CH(3,5-Me2pz)2Ni(NO3)2 moieties, with the nickel atoms exhibiting a distorted octahedral structure with a scorpionate-κ2 and two bidentate nitrato
