Supramolecular Coordination Assemblies Constructed From Multifunctional Azole-Containing Carboxylic Acids

“…These interpenetrating networks of coordination polymers are also an interesting focus of attention currently [29]. For example, the multifunctional ligand terazole-1-acetic acid (Htza) has been used successfully in the synthesis of a series of coordination polymers [30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51] for its variety of coordination styles on the tetrazole and carboxylate group ends. Recently, we and Yu et al .…”

“…Recently, we and Yu et al . independently and simultaneously synthesized a series of Cu II compounds assembled with Htza and published the analysis of their magnetic properties [51,40].…”

Preparation and characterization of the first coordination compounds of tetrazol-2-ylacetic acid

“…Moreover, 1-TzaH was found to generate heterometallic Cu II -Ln III (Ln = Gd, Nd) complexes with Cu 12 Ln 6 clusters [16]. Magnetic studies of manganese(II) and copper (II) complexes revealed weak exchange interactions between the metal ions bridged by tetrazol-1-ylacetate ligand [8][9][10][11]16]. Triorganotin tetrazol-1-ylacetates, (1-Tza)SnR 3 , R = aryl, alkyl, were found to show good antifungal activities in vitro [17].…”

“…The presence of several donor centers and capacity for deprotonation lead to diversity of coordination modes of this ligand and as a consequence to manifold architectures of formed complexes. To date, series of M II (1-Tza) 2 complexes, where 1-Tza = tetrazol-1-ylacetate, M II = Mn, Zn [8], Cd, Co [8,9], Cu [9][10][11]; Ag(1-Tza) [9,12], Ln III (1-Tza) 3 X 2 , where Ln III = La, Pr, Nd; X = H 2 O, MeOH [13,14] have been reported. Also several tetrazol-1-ylacetate complexes of Cd II , Co II and Cu II with 2,2′-bipyridyl and 1,10-phenanthroline as coligands have been characterized [15].…”

“…The crystal structure of complex 1 differs drastically from that of isomeric copper(II) tetrazol-1-ylacetate Cu(1-Tza) 2 . Cu(1-Tza) 2 is also 2D coordination polymer, however in this compound the Cu atoms are four coordinated and ligands play the role of bridges between two metal atoms (carbonyl O atoms do not participate in coordination) [9][10][11]. Complex 2 is molecular complex (Fig.…”
