(Pyridine) (trisubstituted phosphine) gold (I) salts. These compounds have antiarthritic activity. They can be prepared by reacting a halo (trisubstituted phosphine) gold (I) compound with a silver salt and pyridine.
Exploration of multiple bonds between superatoms remains an uncharted territory. In this study, we present the synthesis and characterization of N2-type superatomic molecules featuring triple bonds between two superatoms. The successful synthesis of M2Au17 (M = Pd, Pt) nanoclusters hinged upon the photoinduced fusion of MAu12 superatoms, achieved through sequential electron transfer and detachment
超原子之间多重键的探索仍然是一个未知领域。在这项研究中,我们介绍了两个超原子之间具有三键的 N 2型超原子分子的合成和表征。 M 2 Au 17 (M = Pd, Pt) 纳米团簇的成功合成取决于 MAu 12超原子的光致聚变,这是通过连续的电子转移和 [AuPR 3 ] +物质的分离来实现的。通过 X 射线晶体学证实了固态结构,并通过密度泛函理论 (DFT) 计算阐明了它们的电子结构。对电子吸收特性的分析,加上时间相关的 DFT 计算,揭示了超原子分子轨道之间对称性相关的电子跃迁性质,类似于在传统分子中观察到的情况。

Complexes of gold(I) with a variety of unidentate and potentially chelating P-, As-, Sb-, and S-donor ligands have been characterised by analysis, 1H n.m.r., i.r., and u.v.–visible spectroscopy, and electrical conductivity. In the majority of cases, the gold atom is two co-ordinate, [AuX(L)] or [XAu(L′–L′)AuX](L = unidentateligand, L′–L′= bidentateligand, X = Cl, Br, or SCN), but a few examples of
