The intramolecularly N→Sn coordinated stannylene L(Cl)Sn (1), where L is {2,6-(Me₂NCH₂)₂C₆H₃}⁻, has been used as a ligand for silver(I) and gold(I) compounds. The reactions of 1 with AgX (X = OAc, acac, and Hfac) proceeded as substitution reactions and generated in situ the stannylenes L(X)Sn and AgCl, subsequently giving the complexes [{L(OAc)Sn}·AgCl]₄ (2), [{L(acac)Sn}·AgCl]₄ (3), and [{L(Hfac)Sn}₂·Ag(Hfac)] (4). In contrast, reactions of 1 with [(THF)Ag{HB(3,5-(CF₃)₂Pz)₃}] and [(Me₂S)·AuCl] proceeded without any evidence of chloride substitution and provided the complexes [{L(Cl)Sn}·Ag{HB(3,5-(CF₃)₂Pz)₃}] (5) and [{L(Cl)Sn}·AuCl] (6). All complexes were characterized by multinuclear NMR spectroscopy, electrospray ionization mass spectrometry, and single crystal X-ray diffraction analysis. DFT calculations accompany the experimental work. While the theoretical studies suggested the presence of the Sn→Ag interactions in 2–5, the covalent nature of the Sn–Au bond was evaluated for 6.

Ag（I）和Au（I）络合物中作为配体的N，C，N配位亚锡基

分子内的N→Sn配位的亚锡基L（Cl）Sn（1）（其中L为{2,6-（Me ₂ NCH ₂）₂ C ₆ H ₃ } ^-）已被用作银（I）的配体和金（I）化合物。1与AgX的反应（X = OAc，acac和Hfac）作为取代反应进行，并原位生成亚锡L（X）Sn和AgCl，随后得到配合物[{L（OAc）Sn}·AgCl] ₄（2），[{L（acac）Sn}·AgCl] ₄（3）和[{L（Hfac）Sn} ₂ ·Ag（Hfac）]（4）。相反，1 [[THF] Ag {HB（3,5-（CF ₃）₂ Pz）₃ }]和[（Me ₂ S）·AuCl]的进行没有任何氯取代的证据，并提供了络合物[{L（Cl ）Sn}·Ag {HB（3,5-（CF ₃）₂ Pz）₃ }]（5）和[{L（Cl）Sn}·AuCl]（6）。所有配合物的特征在于多核NMR光谱，电喷雾电离质谱和单晶X射线衍射分析。DFT计算伴随着实验工作。虽然理论研究表明在2 – 5中存在Sn→Ag相互作用，Sn-Au键的共价性质被评估为6。
