The synthesis and characterization of the copper(II) complex [Cu-2(dpt)(2){(mu-O2C)[(eta(5)-C5H4)Fe(eta(5)-C5H5)]}(2)](ClO4)(2) (1), where dpt dipropylenetriamine, are reported, and its structure was determined by single-crystal X-ray analysis. The compound crystallizes in the monoclinic system, space group P2(l)/n, With a = 9.920(2) Angstrom, b = 12.925(2) Angstrom, c = 15,768(3) Angstrom, beta = 93.17(1)degrees, and Z = 2. The cationic part of 1 shows a tetrametallic core in which two ferrocenecarboxylato groups act as (O,O') bridging ligands between two copper(II) ions with a square-pyramidal environment. Susceptibility measurements on this compound indicate a ferromagnetic, albeit weak, coupling between the two paramagnetic centers, with best-fit values of J = +2.5(3) cm(-1) and g(iso) = 2.12(1). Magnetostructural correlations can be qualitatively explained on the basis of the topology of their chairlike core. A quantitative investigation has been performed by means of ab initio density functional theory based calculations in the broken-symmetry approach.
