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, Dc=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
