A bismuth(Ⅲ) complex 1 (H2-4,4’-bipy)Bi(HPPA)5(H2PPA)·4H2O (H2PPA = p-hydroxy-phenylacetic acid, 4,4’-bipy = 4,4 -bipyridyl) was hydrothermally synthesized from p-hydroxy-phenylacetic acid (H 2 PPA), Bi(NO 3) 3 ·6H 2 O and 4,4 -bipyridyl, and characterized by elemental analysis, IR, molar conductivity and TG. The single-crystal X-ray diffraction studies demonstrated that the complex is of monoclinic system, space group P21 with a = 10.928(7), b = 22.558(7), c = 11.313(7), β = 91.864(4)°, V = 2787.7(4)3 , Z = 2, C58H61BiN2O22 , Mr = 1347.07, F(000) = 1364, Dc = 1.605 g/cm-3 , μ(MoKα) = 3.247 mm-1 , the final R = 0.0269 and wR = 0.0540 for 9776 observed reflections with Ⅰ > 2σ(Ⅰ). The bismuth(Ⅲ) is seven-coordinated with O atoms, forming a monocapped octahedral geometry. Complex 1 further forms a 3D supramolecular architecture by hydrogen bonds and π-π stacking interactions. Moreover, the interaction between the complex and DNA was studied by EtBr fluoescent probe.
