are the synthesis, structure, and photophysics of the iodo-substituted cyclic trinuclearcopper(I) complex, Cu3[4-I-3,5-(CF3)2Pz]3 supported by a highly-fluorinated pyrazolate in comparison with its previously reported 4-Br/4-Cl analogues. The crystal structure is stabilised by multiple supramolecular interactions of Cu3⋯I and hydrogen/halogen bonding. The photophysical properties and supramolecular

Pyrazoles represent important building blocks for the preparation of bioactive compounds and a large variety of materials, due to their rich coordination chemistry. Unusual and interesting properties may be imparted to molecules embodying highly fluorinated pyrazoles, but to date only few examples of polyfluorinated pyrazoles have been described. In this work we report an improved preparation of 3,5-bis(trifluoromethyl)-1H-pyrazole, the subsequent transformation into hitherto unknown 4-functionalized (F, Cl, Br, I, NO2, NH2) derivatives and the evaluation of selected chemical and physical properties of these compounds.

mass spectrometry. The copper(I)-containing MOF crystallizes in the hexagonal crystal system within the chiral space group P6322 (no. 182) and the unit cell parameters are as follows: a = 23.630(5) Å, c = 41.390(5) Å, V = 20 015(6) Å3. M[CFA-4] features a porous 3-D structureconstructedfrom pentanuclear copper(I) secondary building units CuI5(pz)6}− (pz = pyrazolate). Cu(I)[CFA-4] is fully characterized
