Synthesis and Structures of Silver(I) and Copper(I) 3,5-Dipentyl-1,2,4-Triazolates

Abstract

The Ag(I) and Cu(I) complexes of 4-amino-3,5-dipentyl-4H-1,2,4-triazole (4-NH 2 -3,5-(C 5 H 11 ) 2 tz) and 3,5-dipentyl-1H-1,2,4-triazole (3,5-(C 5 H 11 ) 2 tzH) have been synthesized and characterized. X-Ray analysis shows that {Ag 4 [4-NH 2 -3,5-(C 5 H 11 ) 2 tz] 6 }(BF 4 ) 4 is a tetranuclear complex featuring an Ag 4 tz 6 cluster; {Ag[3,5-(C 5 H 11 ) 2 tz]} n exhibits a 3D structure of lvt-a topology; and {Cu 2 [3,5-(C 5 H 11 ) 2 tz]Br} n is a Cu 4 Br 4 -cluster based 3D complex with the dia topology.

Relaying Isomerism from Ligands to Metal Complexes: Synthesis and Structures of Four Isomeric Binary Silver(I) 3,5-Dibutyl-1,2,4-triazolates

“…The structural role of the 3,5-substituents can be summarized as follows: the arrays of closely piled substituents act as the template to organize the Ag-tz skeletons to form the most compact structures. This conclusion appears to be valid for some binary copper(I) 1,2,4-triazolates, as discussed in our two recent articles involving a pair of complexes, the 2-fold interpenetrated α-[Cu(3,5-Me 2 tz)] n and [Cu(3,5-Bu 2 tz)] n , , as well as another pair of complexes, [Cu(3,5-Bu 2 tz)] n and [Ag(3,5-(C 5 H 11 ) 2 tz)] n …”

The TG/DSC measurements under air show that these complexes are stable up to 200, 280, and 260 °C for [Ag(3,5-nBu 2 tz)] n , [Ag(3,5-iBu 2 tz)] n , and [Ag(3,5-sBu 2 tz)] n , respectively (Figure S9−S11, Supporting Information).…”
