A novel (CF3SO3−)6 cluster with multiple F  · · ·  F interactions: crystal structure of a self-assembled trinuclear Ag(I) complex with the tripodal ligand tris(2-benzimidazolylmethyl)amine

Self-assembly of silver(I) trifluoromethanesulfonate with the tripodal ligand tris(2-benzimidazolylmethyl)amine (ntb) affords the trinuclear complex [Ag3(ntb)2](CF3SO3)3, which exhibits a rhombohedral network formed from N–H⋯O hydrogen bonds and weak Ag⋯O interactions linking [Ag3(ntb)2]3+ cations with a novel S6-symmetric (CF3SO3−)6 cluster consolidated by multiple F⋯F interactions.
