A new complex associated with Mn ion,[Mn(Hbibm)(S04)]·0.5H20(1,Hbibm=2,2-bibenzimidazole),was prepared under solvothermal conditions,and characterized by singlecrystal X-ray diffraction,elemental analysis and IR spectra.The complex belongs to the triclinic system,space group P(1) with a=8.9250(5),b=12.8022(8),c=13.3505(8) (A),a=66.614(2),β=72.567(2),γ=80.627(2)0,ν=1334.1(1),(Α)3,Ζ=1,Dc=1.565 g/cm3,S=0.996,μ=0.628 mm-1,F(000)=644,R=0.0447 and wR=0.0586 for 5155 observed reflections (I> 2σ(I)).Complex 1 is a mononuclear Mn(Ⅱ) complex.The π-π interactions and interchain hydrogen-bonding interactions further extend the mononuclear for 1,generating a 3D supramolecular architecture.Complex 1 shows strong blue fluorescent emissions in the solid state upon 395 nm photo-excitation at room temperature.
