| Summary: | Bis-benzimidazolium salt (

)-2,2′-bis[2′′-(

-picolyl-benzimidazoliumyl)ethoxy]-1,1′-binaphthyl hexafluorophosphate
[(

2
and its NHC palladium(

) complex [(
S
)-LPd](PF

)
2
(
1
) have been prepared and characterized. Complex
1
is formed by one tetradentate mixed ligand
(
S
)-L
and one Pd(
ii
) ion, in which one 15-membered ring and two 6-membered rings are present. In this complex, intramolecular π-π interactions between naphthalene rings and benzimidazole rings are observed. Additionally, the catalytic activity of complex
1
in three types of C-C coupling reactions (Suzuki-Miyaura, Heck-Mizoroki and Sonogashira reactions) was investigated. The results show that complex
1
is an effective catalyst in these coupling reactions.
