Synthesis and Structure of a Novel Supramolecular Complex with 1D Twisted Structure

Abstract

Abstract: A new bidentate ligand: 4,4′-bis(imidazol-1-ylmethyl)-2,2′-biphenyl(L) was designed and synthesized. Its Mn(Ⅱ) complex [(MnL₃)(ClO₄)₂·2H₂O]_n crystallizes in orthorhombic system, space group Pca2₁ with a=3.392 1(11) nm, b=1.010 3(2) nm, c=1.791 5(4) nm, V=6.140(3) nm₃, Z=4, D_c=1.334 g/cm₃, F(000)=2 564, R=0.049 6, wR₂=0.075 4, (Δρ)_max=0.263×10³e/nm₃, (Δρ)_min=-0.237×103 e/nm₃. In the titled complex, each ligand L adopts a "Z" conformation and binds with two Mn(Ⅱ) ions and each Mn(Ⅱ) ion binds with six L ligands to give a one-dimensional twisted supramolecular complex.

Key words: Supramolecule, Mn(Ⅱ) complex, One-dimensional twisted structure, Aromatic ligand
