Synthesis and Structure of 1.5Zn(phen)3·L·3NO3 Supramolecule (phen = o-Phenanthroline, L = 4-Aminoacetophenone Thiosemicarbazone)

摘要

A supramolecular framework, 1.5Zn(phen)3·L·3NO3 (C63H48Zn1.5N16O9S), has been synthesized.The ligand L was synthesized by the condensation of p-aminoacetophenone with thiosemicarbazide.The crystal belongs to the monoclinic system, space group C2/c, with a = 31.005(2), b = 15.114(2), c = 24.887(3) -, β = 94.260(2)o, Z = 8, V = 11630(2) -3, Dc = 1.489 g/cm3, Mr = 1303.29, λ(MoKα) = 0.71069 -, μ = 0.735 mm-1, F(000) = 5368, Rint = 0.0699, R = 0.0505 and wR = 0.0707.Two independent Zn atoms are both coordinated by six N atoms from three phen ligands.π-π and C-H…π interactions among the L ligands and Zn(phen)3 cations, π-π and C-H…π interactions among the Zn(phen)3 cations and N-H…O hydrogen bonds among the L ligands and nitrate anions connect the whole structure into a 3-D supramolecular framework.
