Halogenated 1,3,5-triazapentadienyl ligands [N(C3F7)C(C6F5)N}2]−, [N(CF3)C(C6F5)N}2]− and [N(C3F7)C(2,6-Cl2C6H3)N}2]−, alone or in combination with other N-donors like CH3CN, CH3(CH2)2CN, and N(C2H5)3, have been used in the stabilization of thermally stable, two-, three- or four-coordinate silver(I) adducts. X-Ray crystallographic analyses of [N(C3F7)C(C6F5)N}2]Ag}n, [N(C3F7)C(C6F5)N}2]Ag(NCCH3)}n, [N(C3F7)C(2,6-Cl2C6H3)N}2]Ag(NCCH3)}n, [N(CF3)C(C6F5)N}2]Ag(NCCH3)2}n and [N(C3F7)C(C6F5)N}2]Ag(NCC3H7)}n revealed the presence of bridging 1,3,5-triazapentadienyl ligands bonded to silver through terminal nitrogen atoms. These adducts are polymeric in the solid state. [N(C3F7)C(2,6-Cl2C6H3)N}2]AgN(C2H5)3 is monomeric and features a 1,3,5-triazapentadienyl ligand bonded to Ag(I) in a κ1-fashion via only one of the terminal nitrogen atoms. The solid state structure of [N(C3F7)C(C6F5)N}2]H has also been reported and it forms polymeric chains via inter-molecular N–H⋯N hydrogen-bonding.

A new class of fluorinated or polyhalogenated triazapentadienes are disclosed. The synthesized triazapentadienes are thermally stable, soluble in typical solvents and have several metal binding sites for complexation with metal ions. The compounds are prepared as colorless crystalline solids. Synthesis takes advantage of a reaction with triethylamine. Synthesized triazapentadienes (with and without complexed metals) inhibit bacterial growth of both Gram positive and Gram-negative bacteria.
