A new pentadecanuclear manganese(II,III) complex derived from tert-butylphosphonic acid with formula [Mn-15(mu(4)-O)(6)(mu(3)-O)(2)(mu(2)-CH3O)(4)(CH3O)(2)(C4H9PO3)(10)(4-dmbpy)(2)]center dot 6MeOH (1) (C4H9PO3H2 = tert-butylphosphonic acid, 4-dmbpy = 4,4%26apos;-dimethyl-2,2%26apos;-dipyridyl) is reported. Complex 1, with an unprecedented Mn-15 topology, shows four different coordination modes of the tert-butylphosphonate bridging ligand: 6.222, 5.221, 4.211 and 3.111. The magnetic properties of 1 are reported. Magnetic susceptibility measurements indicate bulk antiferromagnetic coupling.
