Molecular architectures of cationic [Pd(η3-C3H5)(pzbp2py)]+ complexes and and as counteranions (pzbp2py=2-[3,5-bis(4-butoxyphenyl)pyrazol-1-yl]pyridine)
摘要:
The crystal structures of two complexes containing the 2-[3,5-bis(4-butoxyphenyl)pyrazol-1-yl]pyridine (pz(bp2)py) ligand bonded to the [Pd(eta(3)-C3H5)](+) fragment and BF4- and CF3SO3- as counteranions (1 and 2, respectively) have been solved and their molecular architectures compared. The compounds exhibit a D-2 network based on weak interactions in which the counterion plays an important role. The molecular layers in the D-2 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. (c) 2006 Elsevier B.V. All rights reserved.
