Abstract
The reaction of N-n-Bu4MnO4 with Mn(OAc)(2). 4H(2)O, pyridine and butyric a cid in absolute EtOH leads to the high-yield formation of the oxo-centered trinuclear Mn complex, [Mn3O(O2CC3H,(7))(6)(C5H5N)(3)]. ClO4. The complex c rystallizes in orthorhombic, space group Pna2(1) with a = 19.588(7), b = 20 .194(6), c = 12.491(5) Angstrom. Variable temperature solid state magnetic susceptibility study shows that the antiferromagnetic exchange interaction is weak, and the exchange integral J = -12.36 cm(-1).
