Di-μ-chloro-bis{chloro[3,5-dimethyl-1-(thiocarbamoyl)pyrazole-κ2N2,S]cadmium(II)}

“…The complex of 3,5-dimethyl-1-(thiocarbamoyl)pyrazole with cadmium chloride was obtained as a part of our systematic studies on pyrazole-based complexes (Jaćimović et al, 1999;Tomić et al, 2000; Mé szá ros Szé csé nyi et al, 2001; Mé szá ros Szé csé nyi, Leovac, Č ešljević et al, 2003;Jaćimović et al, 2003). The ligand 3,5-dimethyl-1-(thiocarbamoyl)pyrazole, L, was synthesized by a reaction of thiosemicarbazide with acetylacetone in an acidic aqueous solution and its crystal structure was recently reported (Ková cs et al, 2005).…”

Synthesis and Structures of Zinc(II) and Cadmium(II) Complexes with (η6‐Benzenecarboxylate) Chromium Tricarbonyl and Pyrazole Derivatives

“…Thus, by using 5‐phenyl pyrazole‐3‐carboxylic acid and 3‐phenyl pyrazole‐4‐carboxylic acid 2D and 3D structures were obtained, in which the zinc atom is four‐ and fivefold coordinated 25b. On the other hand a similar structure to compounds 1–4 was observed in [Zn(CH 3 COO) 2 (3‐amino‐5‐phenyl pyrazole) 2 ] 27a…”

Unusual Structures, Phase Behavior, and Fluorescent Properties of 3-phenyl-1-(pyridin-2-yl)-1H-pyrazol-5-amine and Its’ ZnCl2 Complex

“…7,[12][13][14] The strategy of incorporating cation and/or anion binding sites that can communicate with a fluorophore, into a single molecule, has been reviewed, 15 and Blight and colleagues have recently reported the first example of emissive tuning for an Ir(III) complex via second-sphere coordination involving triple hydrogen bonding, and yielding a higher order structure. 16 The pyrazole core reported herein, with an aromatic R 1 , has been previously reported, [17][18][19] and limited examples have been characterized crystallographically, for example, with R 1 = phenyl, 20 2-pyridyl, 21,22 or symmetrically 2,6-substituted pyridyl, 23 but in all cases with R 2 = H (Fig. 1.)…”
