“…Two L − ligands are bonded in a tri(bidentate) manner bridging three metal centers, and the third L − ligand is bonded in a bis(bidentate) manner bridging two metal centers. The terminal Cu(1) is three coordinated by two nitrogen atoms from two L − ligands and one M-M bond, the Cu-N distances are 1.90(9) and 1.910(8) Å, which are shorter than those found in copper(II) triazenide 1.973 to 2.088 Å [19]. Another terminal Cu(3) is four coordinated by three nitrogen atoms from three L − ligands and one M-M bond, the Cu-N distances are 1.946(9), 1.962(9), and 1.987 (10) Å.…”

“…Interest in triazene–metal complexes mainly derives from their structural properties. Triazene ligands can vary in their electron‐donor ability, as well as their potential to form bridging compounds or act as bidentate ligands (Scheme ) 9, 107. A number of metals can be bound to triazenes, including nickel,108 copper,109 platinum,110 cobalt,111, 112 ruthenium,9 and osmium 9.…”

Triazenes (RN=N-NR'R") are a class of compounds that hold much promise in preparative chemistry as they are reactive groups which are both stable and adaptable to numerous synthetic transformations. Useful to scientists in pharmacology, total synthesis, polymer technology, and the construction of novel ring systems, to name a few areas, triazenes also have a tendency to surprise chemists with new reactions and increasing applicability. This review highlights some of the recent advances and diversity possible with these types of systems.

Aryl triazenes have been studied for over 130 years concerning their interesting structural, anticancer, and reactivity properties. They have been used in medicinal, combinatorial chemistry, in natural synthesis and as organometalic ligands. 1 Triazenes compounds, characterized by having a diazoamino group (-N=N-N<), commonly adopt a trans configuration in the ground state. 2,3 In this paper, we show the crystal structure of a new triazene ligand (triazene 1,3-di(2-methoxyphenyl) (Fig. 1).The compound was prepared by the following method: A 1 liter flask was charged with 100 g of ice and 150 ml of water and then cooled to 0˚C in an ice-bath. To this was added 12.30 g (0.10 mol) of o-anisidine and 13 g (0.13 mol) of hydrochloric acid (d = 1.18 g/ml). To this solution was added a solution of NaNO2 containing 4.10 g (0.06 mol) in 25 ml of water during a 15 min period. After mixing for 15 min a solution containing 14.76 g (0.18 mol) of sodium acetate in 45 ml of water was added. After mixing for 45 min the brown product was filtered and dissolved in Et2O, and was crystallized in a freezer. Yield, 50% (6.85 g). Recrystallization from Et2O afforded the product as an orange crystalline material. M. P. 95 -97˚C.The crystal structure of triazene-1,3-di(2-methoxyphenyl) was solved by direct methods and refined by full-matrix least squares using the program SHELXTL-98. 4 The H atoms were refined isotropically. The molecular structure of crystalline triazene-1,3-di(2-methoxyphenyl) is presented in Fig. 2
