A dinuclear Cu(II) complex, [Cu2(OAc)2(tpxn)(H2O)2](PF6)2 [tpxn = N,N,N′,N′-tetrakis(2-pyridylmethyl)-1,4-xylenediamine], was synthesized and characterized by single-crystal X-ray analysis. The compound crystallizes in the monoclinic space group P21/c with a = 9.310(4), b = 10.880(4), c = 20.628(8)Å, β = 91.581(6)°, V = 2088.6(14)Å3, Dcalcd = 1.704 g/cm3, and Z = 4. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0343 and 0.0923, respectively, for all 4731 independent reflections. The complex contains two square-pyramidal Cu(II) ions bound to both terminal tridentate sites of tpxn.
