bridging ligands, three Mo2 dimers of the type [Mo2(DAniF)3](E2CC10H6CE2)[Mo2(DAniF)3] (DAniF = N,N′-di-p-anisylformamidinate; E = O, S) have been synthesized and characterized by X-ray diffraction. These compounds can be generally formulated as [Mo2]–naph–[Mo2], where the complex unit [Mo2] ([Mo2(DAniF)3(μ-E2C)]) functions as an electron donor (acceptor) and the naphthalene (naph) group is the bridge. The
使用2,6-萘二甲酸酯及其硫醇化衍生物作为桥联配体,可以得到[Mo 2(DAniF)3 ](E 2 CC 10 H 6 CE 2)[Mo 2(DAniF)3 ] [Mo 2(DAniF)3 ]类型的三个Mo 2二聚体(DAniF =已经合成了N,N′-二-对-茴香基甲酰胺酸酯; E = O,S),并通过X射线衍射对其进行了表征。这些化合物通常可以配制成[沫2 ] -naph- [沫2 ],其中,所述复合单元[沫2 ]([沫2(DAniF)3(μ-E 2C)])充当电子给体(受体),而萘基(萘基)是桥。由中性前体的单电子氧化生成的混合价(MV)配合物在近中红外区显示弱的,非常宽的间隔电荷转移吸收带。MV络合物的电子耦合矩阵元素H ab = 390–570 cm –1是根据Mulliken-Hush方程计算得出的,该方程介于先前报道的苯基(ph)和联苯(biph)类似物之间。由三个具有相同[Mo
