【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=0.263×103 e/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.更多还原
