摘要：
Intramolecular hydrogen bonding and cation pi-interactions can be used to favour cis isomers of [W(CO)(4)(PRPh2)(2)](R = 2-pyridyl or phenyl) type complexes. The changes in isomerization equilibrium can be switched by protonation or deprotonation of the 2-pyridyl groups. (C) 2000 Elsevier Science S.A. All rights reserved.
