摘　　要：Two new isomeric Au complexes, Au（PPh3）（bmt）, have been synthesized via the reaction of Au（PPh3）CI with 2-benzimidazolethiol （Hbmt） in dichloromethane （CH2Cl2） solution. Their crystal structures were determined by elemental analysis and single-crystal X-ray diffraction studies. Complex 1 crystallizes in the monoclinic system, space group C2/c with a = 19.589（2）, b = 21.1368（15）, c = 23.424（2） A, β = 108.346（4）°, V= 9206.1（14） A3, Mr = 1216.85, Dc = 1.756 g/cm3, μ = 6.566 mm^-1, F（000） = 4704, Z = 8, the final R = 0.0563 and wR = 0.1028 for 8125 reflections with I 〉 2σ（I）. Complex 2 crystallizes in the monoclinic system, space group P21/n with a = 9.627（3）, b = 21.384（8）, c = 22.308（8） A, β = 92.068（6）°, V= 4590（3） A3, Mr = 1216.85, Dc = 1.761 g/cms, μ = 6.585 mm^-1, F（000） = 2352, Z = 4, the final R = 0.0500 and wR = 0.0883 for 10477 reflections with I 〉 2σ（i）. X-ray diffraction studies reveal that complexes 1 and 2 both feature a 1D chain along the a axis.Two new isomeric Au complexes, Au（PPh3）（bmt）, have been synthesized via the reaction of Au（PPh3）CI with 2-benzimidazolethiol （Hbmt） in dichloromethane （CH2Cl2） solution.
