Pyrazoles and pyrazolides—flexible synthons in self-assembly
TL;DR: The chemistry of the pyrazole ring is summarized, and the metal coordination modes adopted by 1H-pyrazoles and their anions are reviewed, highlighting the wide structural diversity in apparently simple main group pyrazolides.

Syntheses, Crystal Structures, and Magneto−Structural Correlations of Novel CuII Complexes Containing a Planar [Cu(μ-L1)]2 (HL1 = 3-(2-Pyridyl)pyrazole) Unit: From Dinuclear to Tetranuclear and Then to One-Dimensional Compounds
TL;DR: Seven new Cu(II) complexes based on a binuclear planar unit, synthesized and characterized by elemental analysis, IR, and X-ray diffraction, feature "pure" dinuclear, 3 and 5 tetranuclear, and 4, 6, and 7 pseudodinuclear moieties.

Coordination Versatility of Pyrazole‐Based Ligands towards High‐Nuclearity Transition‐Metal and Rare‐Earth Clusters
TL;DR: In this article, the progress made by pyrazole-based ligands in the formation of new transition-metal and rare-earth clusters is discussed, as well as other interesting supramolecular structures, such as metallocycles or metallohelicates.

Coordination of Pyridine-Substituted Pyrazoles and Their Influence on the Spin State of Iron(II)
TL;DR: In this article, the magnetic and Mossbauer spectral properties of [NiN6]X2 type complexes have been investigated and it has been shown that the spin transition is discontinuous and associated with hysteresis with Tc ↓ 173 K for decreasing temperature and Tc ↑ 183 K for increasing temperatures.

Octamolybdenum oxo-pyrazolate clusters. Syntheses, characterization, and crystal and molecular structures of the Mo(V)/Mo(VI) and Mo(VI) octamolybdenum clusters Mo8(pz)6O18(pzH)6 and Mo8(pz)6O21(pzH)6
TL;DR: Two octamolybdenum compounds, containing both bridging pyrazolate and terminal pyrazolc ligands, have been prepared by the reaction of molten pyrazole with moly bdenum oxides, and their structure has been determined by single-crystal X-ray diffraction as discussed by the authors.
