Synthesis and Structure of a Novel 2D Network of Silver Complex with Di-Schiff Base Ligand

Abstract

Abstract: A new di-Schiff base ligand, 1,2-bis(3'-pyridylmethyleneamino)ethane(L), was designed and its Ag(Ⅰ) complex[Ag₂(L)₂](CF₃SO₃)₂ was synthesized. The crystal structure analysis indicates that the complex crystallizes in monoclinic system, space group of C2/c with a=3.770 4(2) nm, b=0.797 90(10) nm, c=2.471 3(2) nm, β=101.840(10)°, V=7.276 5(12) nm³, Z=8, D_c=1.808 g/cm³, F(000)=3936, R=0.058 3, wR=0.076 6, (Δρ)_max=0.657×10³e/nm ³,(Δρ)_min=-0.562×10³e/nm³. It is interesting that one L ligand coordinates to three Ag(Ⅰ) atoms using four N atoms, while another L ligand connects two Ag(Ⅰ) atoms with three of four N atoms and one N atom keeps free of coordination.

Key words: Supramolecule, Silver(Ⅰ) complex, Schiff base, Network structure
