| Abstract: | Two new isomeric Au complexes,Au(PPh3)(bmt),have been synthesized via the reaction of Au(PPh3)Cl 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) (A)3,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) (A)3,Mr = 1216.85,Dc = 1.761g/cm3,μ = 6.585 mm-1,F(000) = 2352,Z = 4,the fmal R = 0.0500 and wR = 0.0883 for 10477reflections with I＞2σ(I).X-ray diffraction studies reveal that complexes 1 and 2 both feature a 1D chain along the a axis. |
