Synthesis, supramolecular architecture and fluorescence property of a mixed ligand 1D Pb(II) coordination polymer Mudi, Prafullya Kumar Pal, Chanchal Kumar Biswas, Bhaskar Pb(II) 1D polymer Phenanthroline X-ray crystal structure Fluorescence property Supramolecular interactions A one dimensional (1D) lead(II) coordination polymer, [Pb(Phen)(NO3)(OAC)(H2O)]n (1) (Phen = 1,10-Phenanthroline; OAc = Acetate) was isolated in crystalline phase and characterized through different analytical techniques. Single crystal X-ray structural analysis of compound 1 revealed that the Pb(II) polymer crystallized in a monoclinic system with P21/c space group. Pb2+ ion adopted a highly distorted octahedral geometry having O3 (water) and O5 (nitrate) at axial positions (∠O3-Pb1-O5 of 145.02°) and acetate oxygen (O4), phenanthroine nitrogens (N3, N4) and oxygen (O2) atom from bridging nitrate made a distorted square plane. This Pb(II) polymer exhibited good fluorescence property in solid state. The steric arrangement of distorted square plane around Pb(II) ion by Phen, acetate and bridging nitrate ion makes a huge gap around Pb(II) ion where a stereo-active lone pair of electrons may possibly be occupied.  Atlanta Publishing House LLC 2019-06-30 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf text/plain https://www.eurjchem.com/index.php/eurjchem/article/view/1849 10.5155/eurjchem.10.2.125-130.1849 European Journal of Chemistry; Vol. 10 No. 2 (2019): June 2019; 125-130 2153-2257 2153-2249 eng https://www.eurjchem.com/index.php/eurjchem/article/view/1849/pdf_1849 https://www.eurjchem.com/index.php/eurjchem/article/view/1849/2630 Copyright (c) 2019 Authors
