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.
