“…The tetrazole 5,5'-(1,4-phenylene)bis-1H-tetrazole (H 2 pbtz), necessary for the preparation of 7, was synthesized from 1,4-dicyanobenzene according to a literature procedure [7]. bistetrazolato ligand is a clean and facile step driven forward by the low solubility of the product.…”

“…Conc. HCl (130 mmol) was added dropwise to this solution and stirred without heating for 0.5 h, reflux the reaction mixture for 12-16 h. Now this reaction mixture was added with 30 mL of water and stirred for another 0.5 h. The aqueous layer was separated from the organic layer and added 100 mmol of acetic acid after few minutes till white crystals are formed [29,30]. Yield: 7.…”

INTRODUCTIONHeterocycles predominantly containing nitrogen have been renowned as a class of auspicious and handy structures for the novel tetrazole chromophore design (e.g., pyridine tetrazole, bis-tetrazole pyridine, bipyridine tetrazole and terpyridine tetrazole ligands) [1][2][3][4][5][6][7] and synthesis of the elevated energy materials. Due to their higher thermal stability, higher heat of formation of these pyridine based derivatives found much imperative applications embracing the improvement of photoluminescent materials [8], protein crystallography [9] and immense variety of many other applications ranging from material science to medicinal field [10][11][12]. One of the most imperative and sensational applications of tetrazole based derivative as the pyridine tetrazole, which has been set up to display extensive appliances particularly in luminescent applications such as indicators, imaging and signal sensors [13,14].These tetrazole based derivatives can be used as a ligand in the configuration of eclectic range of complexes liable upon the nature of the central metal. Recently, lanthanide complexes equipped, which has publicized much more boosted photo luminescent property [15]. Correspondingly, the complexes

Neste trabalho, descreve-se a síntese de novos ligantes e dos seus complexos de Pd(II) com os ligantes 5-(n-alcoxifenil)-2-n-alquiltetrazol (L 1 ) e α,ω-bis-[5-(4-pentoxifenil)-2-alcanotetrazois] (L 2 ). A determinação estrutural através de difração de raios-X do complexo de paládio contendo L 1 revela uma estrutura mononuclear na qual a geometria do cromóforo Pd(L 1 ) 2 Cl 2 é plana e possui um centro de inversão sobre o átomo de paládio. As moléculas de feniltetrazol estão ligadas ao íon metálico de forma monodentada e trans entre si, através de uma ligação σ, Pd-N1. Para o complexo de paládio contendo L 2 , propõe-se uma estrutura dinuclear, ([Pd 2 (L 2 ) 2 Cl 4 ]), com base em dados de espectroscopia de RMN e IV.The new 5-(n-alkoxyphenyl)-2-n-alkyltetrazole (L 1 ) and α,ω-bis-[5-(4-pentoxyphenyl)-2-alkanetetrazoles] (L 2 ) ligands and their Pd(II) complexes have been synthesized. The X-ray diffraction study of the palladium complex with L 1 reveals a mononuclear structure in which the geometry of the Pd(L 1 ) 2 Cl 2 chromophore is planar as required by the inversion center at the palladium atom, where each molecule of phenyltetrazole binds to the metal ion in a monodentate fashion via a Pd-N1 σ-bond. For the palladium complex with L 2 , a dinuclear structure ([Pd 2 (L 2 ) 2 Cl 4 ]) has been proposed on the basis of NMR and IR spectroscopy.
