A bismuth(III) complex [Bi2(PPA)6·(Phen)2] (HPPA = phenylacetic acid; Phen = 1,10-phenanthroline) was synthesized and characterized by elemental analysis and infrared (IR) spectroscopy, its crystal structure was determined by single crystal X-ray diffraction. The crystal of bismuth(III) complex belongs to triclinic system with space group P-1, a=0.9100(6) nm, b=1.2617(8) nm, c= 1.3324(9) nm, α=89.757(8)°, β=87.277(8)°, γ=81.155(8)°, V=1.5099(17) nm3, Dc=1.748 g·cm-3, μ=5.890 mm-1, Z=1, F(000)=780, residual factors R1=0.0484, wR2=0.1090 [I>2σ(I)], S=1.002. The comcomplex is a binuclear bismuth(III) compound, and every bismuth(III) atom is nine-coordinated by six O atoms from three ligands (PPA) and two N atoms from one ligand (Phen) and one bridged O atom, and the coordination polyhedron around the bismuth(III) atom can be best described as a distorted tricapped trigonal-prismatic tetrakaidecahedron geometry, the valence sum of around Bi atom VBi(1)=2.897. The distance of Bi…Bi is 0.4469(2) nm. The complex has a good effect against E. Coli, S. Aureus and B. Subtilis.
