Main group metal – organic frameworks of Bi(V) and Pb(II) derived from 2-[4,6-diamino-3-[3-amino-6-(1-methyamino-ethyl) tetrahydropyran-2-yl] oxy-2-hydroxy-cyclohexoxy]-5-methyl-4-methylaminotetrahydropyran-3,5-diol and their molecular modeling

Abstract

Main group metal complexes of Bi(V) and Pb(II) were synthesized with an organic framework (OF) of 2-[4,6-diamino-3-[3-amino-6-(1-methyamino-ethyl) tetrahydropyran-2-yl] oxy-2-hydroxy-cyclohexoxy]-5-methyl-4-methylamino-tetrahydropyran-3,5-diol (L). Conformational changes and the binding abilities of the organic framework toward Bi(V) and Pb(II) were identified by various physiochemical and spectroscopic measurements including IR, ¹H NMR, UV – vis, molecular modeling, and X-ray powder diffractometry. The lattice parameters of the metal organic frameworks (MOFs) were calculated and were as follows: cell dimension for [Bi(V)L] complex, a = 9.8355 (Å), b = 9.8355 (Å), c = 21.78695 (Å), α = 90.00°, β = 90.00°, γ = 90.00°; cell dimension for Pb(II) complex, a = 11.59609 (Å), b = 15.0373 (Å), c = 6.6854 (Å), α = 90.00°, β = 99.000°, γ = 90.00° at 1.54056A°. Particle size (nm) of the complexes was found to be 10.75 and 8.817 nm, respectively. Molecular models represent a better understanding of the arrangement of the atoms in the molecules in three dimensions.
