Synthesis and X-Ray Diffraction of a Ternary Plumbum Complex

Abstract

A new ternary plumbum complex [Pb(phen)₂(NO₃)₂] (phen = 1,10-phenanthroline) has been synthesized and characterized by IR spectra and single-crystal X-ray diffraction. The crystal belongs to monoclinic crystal system and has space group P2(1)/n with unit cell parameters: a =16.7304(15) Å, b = 7.7529(7)Å, c = 18.1308(17) Å, a = 90º, b = 98.2170(10)º, g = 90º, V = 2327.6(4) ų, Z = 4, M_r = 691.62, D_c = 1.974 Mg/cm³, μ = 7.303 mm^-1, F₍₀₀₀₎ =1328, T = 298(2) K, R = 0.0306, wR = 0.0574 for 11276 reflections with I > 2s(I). In terms of the crystal structure, Pb(II) ion is eight-coordinated with four nitrogen atoms of the two phen ligands and four oxygen atoms of the two nitrate radical anions.
