Abstract
A new binuclear copper (II) complex {[Cu2(phen)2(tar)(H2O)]·8H2O}n (1) has been synthesized and structurally characterized by single-crystal X-ray diffraction analysis. The complex crystallizes in monoclinic system, space group P2(1), with a = 7.1710(5), b = 22.0124(15), c = 10.6691(7) A, β = 102.541(1)°, V = 1643.95(19) A3, Z = 2. Compound 1 is further extended to a 2D supramolecular framework by hydrogen bonds and π–π stacking interactions. Especially, six of the eight uncoordinated water molecules are connected via hydrogen bonding interactions forming 1D chain, which play an important role in the stabilization of the crystal structure. Furthermore, magnetic susceptibility measurements of this complex shows weak antiferromagnetic exchange between the copper (II) ions (J = −5.92 cm−1).
