Mn[Cu(L)(O2CMe)2] · H2O (L = N,N’-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane) was synthesized and the crystal structure determined. (C23H26CuMnN2O8).H2O, monoclinic, space group P21/c, a = 12.017(3), b = 8.217(3), c = 24.786(4) Å , β = 92.10(2)°, V = 2446(1) Å3, Z = 4. The crystal structure consists of ordered dinuclear units with CuII and MnII ions bridged by two oxygen atoms of the Schiff base ligand. The CuII coordination sphere is a slightly distorted square-plane formed by the N2O2 donor set of the Schiff base ligands. The average Cu-O and Cu-N distances are 1.920(1) and 1.957(4) Å , respectively. The coordination around the MnII ion is a distorted tetrahedron with the donor oxygen atoms of the Schiff base ligands and oxygen atoms of the acetate anions. The Cu ··· Mn separation is 3.327(4) Å . There is also one non-coordinating water molecule in the crystal structure. The χ and χT versus T plots, χ being the molar magnetic susceptibility per CuIIMnII unit and T the temperature, has been measured in the 4.9 - 301 K temperature range. The values of the interaction parameters are J = −28.3 cm−1, gMn = 2.01, gCu = 2.07. This indicates an intramolecular antiferromagnetic interaction between CuII and MnII ions.
