Study of the reactivity of tris(pyrazolyl)amine and bis(pyrazolyl)amine ligands toward Rh(I). Crystal structure of [Rh3Cl3(cod)3tdma]·CH3CN (tdma=tris[(3,5-dimethyl-1-pyrazolyl)methyl]amine), a C3-symmetric compound

{Bis[2-(3,5-dimethylpyrazol-1-yl)ethyl]amine-κ3N,N′,N′′}chloropalladium(II) chloride dihydrate

“…When pyrazole is N-bonded to molecules with amine residues that may act as a building-block, it is possible to obtain multidentate ligands. Some are tetradentate with an umbrella-type geometry, while others are only tridentate (Zamora et al, 2004).…”

A new dinuclear copper(II) complex of unexpected formation with the 1-[2-(ethylamino)methyl]pyrazole ligand presents a curious Ferris wheel-like shape at supramolecular self-assembly

“…The syntheses of these ligands and the studies of their reactivity with Ni(II), Co(II), Zn(II) and Cu(II) were carried out by Driessen et al and Sheu et al [5][6][7][8][9][10]. Other studies of the reactivity of theses ligands are reported by Calderazzo et al using Fe(II) [11] and Carpentier et al using Al(III) and Zn(II) [12] as coordination metals.More recently, the syntheses of new types of N-alkylaminopyrazole ligands and the evaluation of their reactivitywith Rh(I) [13][14][15][16], Pd(II) [17][18][19][20], Pt(II) [21], Zn(II) [22] and Cd(II) [23] have been continued by our group. Some of them have been used in the synthesis and stabilization of nanoparticles, even as metal recognizer molecules in metal sensing systems [24][25][26].…”
