摘要
首次研究了在硼簇阴离子[BnHn]2 - (n = 10,12)存在下，银(I)与取代的（苯并咪唑-2-酰基）甲胺Bz - ch2 - nh - R （Bz为1-甲基苯并咪唑，R为苯甲咪唑（L1）或1-异丙基苯并咪唑（L2））的络合反应。确定了苯并咪唑衍生物中取代基R对所合成化合物的组成和结构的影响。配位化合物[Ag(L1)2]xAn (x = 1, An = {Ag[B10H10]}mm -；x = 2, An = [B12H12]2 -)，外配位球具有近硼酸盐阴离子和单齿配位体L1，已合成并进行了结构表征。此外，还得到了双核配合物[Ag2(L2)2[µ-BnHn]]，其中L2是双向配位的，形成一个七元金属环，而阴离子[BnHn]2 - (n = 10,12)作为桥接配体。分析了合成的化合物的结构特征，包括有机配体的配位方式和配位硼簇阴离子化合物的位置异构和键异构的发生。
Substituted (benzoimidazol-2-yl)Methanamines in Silver(I) Complexation in the Presence of Boron Cluster Anions
Silver(I) complexation with substituted (benzoimidazol-2-yl)methanamines Bz–CH2–NH–R (Bz is 1-methylbenzimidazole, R is anisole (L1) or 1-isopropylbenzimidazole (L2)) in the presence of boron cluster anions [BnHn]2– (n = 10, 12) has been studied for the first time. The influence of substituent R in the benzimidazole derivative on the composition and structure of the resulting compounds has been determined. Coordination compounds [Ag(L1)2]xAn (x = 1, An = {Ag[B10H10]}mm–; x = 2, An = [B12H12]2–), featuring closo-borate anions in the outer coordination sphere and monodentately coordinated ligands L1, have been synthesized and structurally characterized. Additionally binuclear complexes [Ag2(L2)2[µ-BnHn]] have been obtained, in which L2 is coordinated bidentately, forming a seven-membered metallacycle, while anions [BnHn]2– (n = 10, 12) act as bridging ligands. The structural features of the synthesized compounds have been analyzed, including the coordination mode of the organic ligands and the occurrence of positional and bond isomerism in compounds with coordinated boron cluster anions.
