| Abstract: | Based on in situ synthesized Schiff base ligand Dppd (Dppd = N-(di(2-pyridyl)methylene)-p-phenylenediamine), a novel dinuclear Mn(II) complex, Mn2(Dppd)4(OAc)2](ClO4)2(CH2Cl2)2 · 2(H2O) (I), was synthesized and characterized by IR and single-crystal X-ray diffraction. The crystals belong to monoclinic system, space group C2/c with a = 26.3868(2), b = 20.0379(4), c = 19.16260(10)Å, β = 126.6900(10)°, V = 8124.61(18) Å3, Z = 4. The complex exhibits a dinuclear structure in which two symmetric Mn(II) atoms adopt somewhat distorted octahedral geometry. The 2D structure is further constructed through intermolecular benzene-benzene offset π···π interactions. |
