A silver coordination compound [Ag(I)(DMT-TTF-py)2CH3CN] ClO4 · CH2Cl2 has been synthesized by reaction of DMT-TTF-py with AgClO4. Structure analysis shows that the cations self-assemble to dimeric units through Ag ··· Ag interactions. Each silver(I) has a T-shaped AgN3 coordination geometry. In the dimeric units, there are short C ··· S and C ··· C contacts between the two DMT-TTF-py molecules. The dimeric units are further assembled to a zigzag packing structure. The cyclic voltametric behavior of the ligand shows two-step reversible redox waves, which are shifted to lower values due to coordination to silver. [ABSTRACT FROM AUTHOR]
