From IR and Raman studies it was evidenced the exobidentate nature of pyrazole ligands as well the µ-1, 1-bridging coordination of azido groups. NMR experiments showed two sets of broadened signals with different intensities indicating the presence of pyrazolato groups in distinct chemical environments. The proposed structure of [Pd 3 (µ-N 3)(µ-Pz) 5] n consisting of a zigzag ribbon in which each (Pz) 2 Pd(Pz) 2 entity is bound to two stacked planar units [Pd(µ-Pz)(µ-N 3)Pd core] with very weak Pd-Pd interaction, based on UV-Vis spectroscopy.255-260engArtigo10.1080/7137383052-s2.0-85148690677
