Molecular architectures of cationic [Pd(η3-C3H5)(pzbp2py)]+ complexes and image and image as counteranions (pzbp2py = 2-[3,5-bis(4-butoxyphenyl)pyrazol-1-yl]pyridine)

The crystal structures of two complexes containing the 2-[3,5-bis(4-butoxyphenyl)pyrazol-1-yl]pyridine (pzbp2py) ligand bonded to the [Pd(η3-C3H5)]+ fragment and View the MathML sourceBF4- and View the MathML sourceCF3SO3- as counteranions (1 and 2, respectively) have been solved and their molecular architectures compared. The compounds exhibit a 2D network based on weak interactions in which the counterion plays an important role. The molecular layers in the 2D arrangement show interpenetration between the substituent-chains on the pyrazole rings. These features are also observed in related compounds bearing only one chain on the pyrazole ring.
