Hydrothermal Synthesis,Crystal Structure and Magnetic Behavior of a Novel 3D Supramolecular Complex [Cu(HDPPZC)(SO_4)(H_2 O)]_2

In the title coordination compound, [Cu(HDPPZC)(SO4)(H2O)](2) (1, HDPPZC = dipyrido[3,2-a:2',3'-c]-phenazine-2-carboxylic acid), has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, elemental analysis and magnetic susceptibility measurement. It crystallizes in triclinic, space group Pi with a = 0.69485(6), b = 0.76878(4), c = 1.76638(13) nm, alpha = 99.437(6), beta = 94.690(6), gamma = 95.735(6)degrees, V = 0.92151(12) nm(3), Z = 1, Cu2C38H24N8S2O14, M-r = 1007.85, D-c = 1.816 g.cm(-3), F(000) = 510, GOOF = 0.988, the final R= 0.0580 and wR = 0.0689. The structural analyses reveal that complex 1 shows discrete dinuclear clusters, which are further linked by hydrogen bonding and pi(...)pi stacking interactions to form a three-dimensional supramolecular compound. Magnetic measurement shows ferromagnetic and antiferromagnetic exchange interactions in the sample.
