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 compl

Deprotonated 1,3-bis(3-acetylphenyl)triazene reacts with Hg(CH3COO)2 and pyridine to give tectonic [HgII(RC6H4NNNC6H4R)2Py] [R = CH3C(O)]. The tectons are linked to pairs as centrosymmetric dimers through reciprocal metal-η2-arene π-interactions. The dimeric units assemble a supramolecular bidimensional lattice through non classical C-H⋯(O)CCH3 bonding.
