Abstract

In this study, the complexation of silver(I) with azaheterocyclic ligands (bipy, phen) in the presence of perchlorinated borate anions, [B₁₀Cl₁₀]^2– and [B₁₂Cl₁₂]^2–, was investigated in acetonitrile. Complexes with the general formula [Ag₂L₄][B_nCl_n] (L = bipy, phen; n = 10, 12) were successfully isolated. The final compounds were characterized using elemental analysis and IR spectroscopy. The structures of the [Ag₂(bipy)₄][B_nCl_n] (n = 10, 12) complexes were elucidated via X-ray diffraction (CCDC nos. 2325088, 2358488). It was determined that the compounds consist of either a binuclear cationic silver(I) complex with azaheterocyclic ligands, [Ag₂(bipy)₄]²⁺, or two mononuclear complexes, {[Ag(bipy)₂]₂}²⁺, with the boron cluster anions forming the anionic part of both complexes. Additionally, weak argentophilic Ag…Ag interactions were observed within the structures.

偶氮杂环配体（bipy, phen）和高氯近硼酸盐阴离子[BnCln]2 - (n = 10,12)的银(I)配合物

在本研究中，研究了银(I)与氮杂环配体（bipy, phen）在高氯硼酸阴离子[B10Cl10]2 -和[B12Cl12]2 -存在下在乙腈中的络合反应。具有通式[Ag2L4][BnCln]的配合物(L = bipy, phen；N = 10, 12)成功分离。用元素分析和红外光谱对化合物进行了表征。[Ag2(bipy)4][BnCln] （n = 10,12）配合物的结构通过x射线衍射（CCDC编号2325088,2358488）进行了鉴定。结果表明，该化合物由两个单核配合物{[Ag(bipy)2]2 +组成，两个单核配合物{[Ag(bipy)2]2}2+组成，硼簇阴离子形成这两个配合物的阴离子部分。此外，在结构内观察到弱的亲银银相互作用。
