The results of solution studies for the formation of 3 in methanol support its solid-state stoichiometry. An interesting feature of 3 is also the presence of π⋯π and C–H⋯π interactions. In the crystal structure of 3,, the central Hg(II) is surrounded by two N atoms from interlocked L forming linear geometry, in which the other four Hg–N and Hg–O bonds are longer and can only be regarded as weak secondary bonds.

On coordination, each triazene was deprotonated and as a result, a resonance structure is formed between nitrogens which let them to be a tridentate ligand.

This software package can be downloaded from the Rigaku x-ray forum. According to the crystal structures of 1 and 2, the N–N bond distances indicate the presence of alternating single and double bonds, and hence the –N=N–NH– moiety. This package is useful for a comprehensive range of tools for 3D structure. Mercury offers a comprehensive range of tools for 3D structure visualization and the exploration of crystal packing. All compounds were characterized by CHN analysis, FT-IR, 1H NMR, and 13C NMR spectroscopy. The related monomeric complexes, ( 3) and ( 4), were prepared by the reacting of the corresponding ligands with Hg(NO 3) 2 salt in methanol as solvent. Mercury Diesel engines offer a sophisticated diesel-engine experience: Advanced turbocharging and injection technologies produce a powerband that’s carefully calibrated for marine performance and outstanding economy.
The prepared triazenes are functionalized by ethoxy and methoxy groups in the ortho positions, respectively. The ability to measure and display distances, angles and torsion angles involving atoms, centroids and planes. Input of hit-lists from ConQuest, or other format files such as CIF, PDB, MOL2 and MOLfile. Synthesis of two new asymmetric ligands: 1-(2-ethoxyphenyl)-3-(2-methoxycarbonylphenyl)triazene (H L) ( 1) and 1-(2-methoxyphenyl)-3-(2-methoxycarbonylphenyl)triazene (H L′) ( 2) are reported. Mercury offers a comprehensive range of tools for structure visualisation and the exploration of crystal packing.
