A copper(II) complex with 1,3-bis(pyrrole-2-methylideneamino)-2-propanol (H3bpmp), [Cu(Hbpmp)]·0.5C2H5OH, was prepared, and the crystal structure at 293 K was elucidated by the single-crystal X-ray diffraction method. The complex crystallized in the monolinic space group C2/c with a = 17.975(2)Å, b = 18.894(2)Å, c = 9.2081(11)Å, β = 113.728(2)°, V = 2863.0(6)Å3, Dm = 1.48 g/cm3, Dc = 1.526 g/cm3, and Z = 8. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0320 and 0.0991, respectively, for all 3378 independent reflections. The complex is essentially a square-planar copper(II) complex with partially deprotonated Hbpmp2−; this mononuclear unit is loosely connected by the axial semi-coordination of the alcohol group of the Hbpmp2− ligand of the neighboring mononuclear unit to form a dinuclear assembly. The temperature dependence of the magnetic susceptibility (4.5 – 300 K) follows the Curie–Weiss law with θ = –1.2 K, showing a weak antiferromagnetic interaction between the copper(II) ions, consistent with the crystal structure.
