A new dinuclear manganese complex [Mn₂(L)₂(2,2'-bipy)₂(H₂O)₅]₂·3H₂O has been synthesized with MnSO₄·H₂O, 2,2'-bibenzoic acid (H₂L) and 2,2'-bipyridine(2,2'-bipy) in the mixed solvent ethanol and water. It crystallizes in monoclinic, space group P1 with a=9.9944(10), b=21.939(2), c=25.628(3) Å, α=108.429(3), β=100.613(4), γ=102.821(3)°, V=4997.9(9) Å³, D c=1.355 g/cm³, Z=2, F(000)=2108, GOOF=1.074, the R=0.0626 and wR=0.1531. The structure of the complex contains two [Mn₂(L)₂(2,2'-bipy)₂] units, ten coordinated H₂O molecules and three uncoordinated H₂O molecules. The fluorescence, thermal stability and magnetic properties of the complex were investigated.
