The crystal structure of the title compound [Mn(sapn)(H2O)2]Br (H2sapn = N,N′-bis-(salicylidene)-1,3-diaminopropane) with formula C17H18N2O4MnBr and Mr = 449.18 has been determined by X-ray diffraction. The crystal is triclinic with space group P ī, a = 7.777(1), b = 10.459(2), c = 11.96(3)?, α = 78.22(1), β =75.16(8), γ = 86.80(5)°, V = 919(3)A3, Dc = 1.631g/cm3, F(000) = 456, μ = 2.917 cm-1 and Z = 2, with R = 0.0428 and wR = 0.1092 for 2427 reflections (I > 2σ(I)). Two nitrogen and two oxygen atoms from the sapn group chelate to the MnⅢ ion, forming a distorted octahedral geometry together with two coordinated water molecules. A bromide anion exists outside as a counter ion.
