Crystal Structure of the Coordination Polymer of Sodium with Hydrazone Derivant of Acetoacetanilide

摘要

One new polymer, [Na(NPHSNPAB)(CH_3OH)]_n, where NPHSNPAB stands for Nphenyl-2-[2-hydroxy-3-sulfo-5-nitrophenylhydrazone]butadione-1,3, has been synthesized and characterized by ~1H NMR and FTIR spectroscopy and single-crystal X-ray diffraction. For this complex: C_(17)H_(17)N_4NaO_9S, M_r = 476.39, triclinic system, space group P1, a = 8.8741(18), b = 10.942(2), c = 12.039(2) ?, α = 65.74(3), β = 77.49(3), γ = 84.30(3)o, V = 1040.3(4) ?~3, Z = 2, D_c = 1.521 g/cm^3, λ = 0.71073 ?, F(000) = 492, S = 1.106, R = 0.0614 and w R = 0.1423 for 2945 observed reflections with I > 2(I). X-ray structural analysis revealed that the structure of NPHSNPAB framework was almost planar by C–H···O, N–H···O, O–H···O, and O–H···S hydrogen bonds. Moreover, sodium(I) center was bound by six O and one N atoms, forming the coordination polymer. The molecular packing diagram showed complicated hydrogen bonds and π···π stacking interaction in the polymer. The average bond distance of the two dicyclic units(3.768 ?) indicated strong π···π stacking interaction. The complex displays greenyellow emission at room temperature.
