Polymeric bidimensional self-assembling of [HgII(RC6H4NNNC6H4R)2Py] (R=m-acetyl) through metal-η2,η2-arene π-interactions and non classical C–H⋯O bonding: Synthesis and X-ray characterization of a bis diaryl symmetric-substituted triazenide complex of Hg(II)

Synthesis and crystal structure of [C6H5Hg(H2NSiMe3)][H2N{B(C6F5)3}2], a phenyl–mercury(II) cation stabilised by a non-coordinating counter-anion

“…The other distances to C(7), C(8) and C(9) are unexceptional. Whereas Hg-C arene distances shorter than 3.00 Å were found in [(C 6 Me 6 )Hg(O 2 CCF 3 ) 2 ] [16] or the mercury(I) compound [(C 6 Me 6 )HgHg][AlCl 4 ] 2 [17], the Hg(1)-C(5) and Hg(1)-C(4) distances in 2 AE CH 2 Cl 2 compare well with the Hg-C arene distances in, for example, 3.574(7) Å ] [19], and {Hg[NNN(PhBr) 2 ] 2 } n [3.297(6), 3.429(6) Å ] [20]. However, NMR spectroscopy does not provide evidence that the dimeric motif is preserved in solution.…”

Properties and Promise of Catenated Nitrogen Systems As High-Energy-Density Materials

“…While parent triazene is not stable in pure form, organic variants are well-known, and common, in synthetic and medicinal chemistry, and examples are extensive. Consistent with theoretical calculations on the parent triazene, all structurally characterized examples are trans. − Such organic triazenes have extensive utility in synthesis, − and due to their ability to alkylate DNA, have also shown potential activity as anticancer drugs. , Metal complexes of triazenes are the most common isolated molecules, and monodendate examples are usually coordinated to late transition metals, − though other complexes exist, such as those with titanium, , main-group metals, and mid-transition metals. , Triazenes are commonly found to bridge pairs of metal ions at short distances to template M–M bonding interactions. − …”

New chelate complexes of trivalent Y and lanthanides (Eu, Ho, Yb) with a triazene N-oxide: Synthesis, structural characterization and luminescence properties

“…Such characteristics make these species also proficient to assemble unique supramolecular aggregates. Recently we have reported some examples of these classes of compounds, with 1D [1][2][3][4] and 2D [5][6][7] polymeric assemblies. The generation ''in situ'' of an alkali metal derivative was also investigated, by reaction of the relatively unstable 3-(4-carboxyphenyl)-1-methyltriazene N-oxide with KOH [8].…”
