The complex-(4’-fluorobenzyl)pyridiniu 2Ni (dto) 2(dto 2- means dithiooxalate dianion)has been pre-pared by reaction of Na 2Ni (S 2 C 2 O 2 ) 2and the 1-(4’-fluorobenzyl)pyridinium chloride salt.The crystallographic data for the title complex:triclini cP1,a=8.5698(8)?,b=9.3461(9)?,c=10.5361(10)?,α=67.177(2)°,β=67.398(2)°,γ=79.611(2)°,V=717.59(12)? 3 ,Z =1.TheNi (dto) 2 2- anion with the Ni atom lying on an inversion center and exhi bits a quasi-planar structure.An extensive hydrogen bond network of C -H...O is clearly observed.The nature and size of cation seems to play an important factor in the type of intermolecu lar interactions as well as the crystal packing in this kind of complexes.
