“…The noxious metal, mercury is recognised to form coordinate complexes with molecules containing N and S binding sites, possessing a stronger affinity for S. [5][6][7][8] Such metal-organic coordination polymers have caught attention because of their intriguing structures and distinctive properties, which find applications in magnetism, sensing and so on. [9,10] Cadmium, non-essential heavy metal, is also identified to instigate DNA damage. Cd II -DNA binding has led to the impediment of enzymatic digestion due to cadmium mediated structural variations.…”

We report three complexes of CdII and HgII with two purine rare tautomers, L1 and L2, highlighting diverse crystallographic signatures exhibited by them. Influence of substituents, binding sites, steric effects and metal salts on the different modes of binding enabled an insight into metal‐nucleobase interactions. L1 interacted with two and three equivalents of Cd(NO3)2.4H2O and HgCl2, respectively, while L2 interacted with two equivalents of HgCl2, altogether leading to three different complexes (1‐3) possessing varied dimensionality and stabilising interactions. The photoluminescent properties of these coordination frameworks have also been probed. Notably, nanoring‐like structures were obtained, as a result of self‐assembly of 3 when investigated by transmission electron microscopy, additionally supported by molecular dynamics simulations.

Two new M(II)-radical complexes [M(hfac) 2 (IM-o-QN)] (M = Ni(1), Zn(2); IM-o-QN = 4'-quinoxalinyl-substituted imino nitroxide; hfac = hexafluoroacetylacetonate) have been synthesized and characterized by X-ray diffraction analysis, element analyses, IR and UV-Visible spectroscopy. X-ray analysis reveal that the structures of both complexes are similar configuration and differently spatial symmetries. The complex 1 crystallizes in the triclinic Pī space group with the respective cell parameters: a = 9.1189(18) Å, b = 9.836(2) Å, c = 18.537(4) Å, α = 75.92(3)˚, β = 81.95(3)˚, γ = 69.32(3)˚, V = 1506.1(5) Å 3 , Z = 2, whereas the complex 2 is in monoclinic C2/c space group with the respective cell parameters: a = 26.996(5) Å, b = 9.5223(19) Å, c = 23.961(5) Å, α = 90.00˚, β = 91.07(3)˚, γ = 90.00˚, V = 6158(2) Å 3 , Z = 8. In two new M(II)-radical complexes, the central M(II)(Ni(1) and Zn( 2)) ions are coordinated by four oxygen atoms from two hfac and two nitrogen atoms from imino nitroxide radicals to form a distorted octahedron. Additionally, the optical properties and thermal analysis of the two complexes are reported.
