The gold complexes n-Bu4N[Au(alpha-tpdt)2] (5), n-Bu4N[Au(dtpdt)2] (4) and n-Bu4N[Au(tpdt)2] (6) based on new dithiothiophene ligands (alpha-tpdt= 2,3-thiophenedithiolate, dtpdt=2,3-dihydro-5,6-thiophenedithiolate and tpdt = 3,4-thiophenedithiolate) have been prepared and characterised. These gold(III) complexes are diamagnetic, but they can be oxidised with iodine to the paramagnetic compounds [Au(alpha-tpdt)2]
基于新的二噻吩基的金配合物n-Bu4N [Au(alpha-tpdt)2](5),n-Bu4N [Au(dtpdtt)2](4)和n-Bu4N [Au(tpdt)2](6)已经制备并表征了配体(α-tpdt= 2,3-噻吩二硫代酸酯,dtpdt = 2,3-二氢-5,6-噻吩二硫代酸酯和tpdt = 3,4-噻吩二硫代酸酯)。这些金(III)配合物是抗磁性的,但它们可以被碘氧化为顺磁性化合物[Au(alpha-tpdt)2](8),[Au(dtpdt)2](7)和n-Bu4N [[Au (tpdt)2] n-2](9),以细粉形式分离,并表现出几乎与温度无关的顺磁化率,室温值为2.5 x 10(-4),2.0 x 10(-4)和5 x 10(-4)mu x mol(-1)。有趣的是 作为多晶样品的中性络合物[Au(alpha-tpdt)2](8)显示了室温下电导率为6 S x cm(-1)且热电功率为5
