Abstract: 
The high-temperature oxidation of the rare earth metals holmium and neodymium with the amine pyrazole gave the two new compounds (1)(infinity)[Ho(Pz)(3)(PzH)(3)] (1) and [Nd(Pz)(3)(PzH)(4)] (2) (pyrazole, PzH = C3H3NNH; pyrazolate anion, Pz(-) = C3H3NN-). 1 exhibits a one dimensional chain structure with the unusually high number of twelve nitrogen atoms that form a hexagonal antiprism as coordination polyhedra around Ho-III. 2 consists of monomeric molecules containing trivalent neodymium with the coordination number of nine. The coordination polymer 1 shows both a higher thermal stability as well as a packing of a dinstinctively higher density than monomeric 2. Both compounds were investigated by low-temperature single crystal X-ray analysis, Mid IR, Far IR and Raman spectroscopy. Simultaneous DTA/TG and temperature dependent x-ray powder diffraction were used as combinatory methods to investigate the thermal properties of both compounds.
