SYNTHESIS, CHARACTERIZATION AND STRUCTURE OF COMPLEXES OF LANTHANUM(III) PICRATE WITH <i>N, N, N′, N′</i>-TETRAPHENYL-3, 6, 9-TRIOXAUNDECANEDIAMIDE

Abstract

Abstract Reaction of lanthanum picrate with N, N, N′, N′-tetraphenyl-3, 6, 9-trioxaundecanediamide (TTD) yields [La (Pic)3 (TTD)], which has been characterized by elemental analysis, IR and 1H NMR spectra and molar conductivity measurements. The complex crystallizes in the orthorhombic space group Pcab with a = 24.006(8), b = 29.140(9), c = 32.084(9) Å and D c = 1.60g cm−3 for Z = 16. Refinement of 5676 reflections (l < 2.0[sgrave](l)) out of 12569 unique observed reflections (2°≤2θ<42°) gave R and Rw values of 0.079 and 0.068, respectively.
