摘要：
The reactivity pattern of [V(Cp)(2)Cl-2] towards the weakly coordinating CF3SO3 anion in the absence of chelating or bridging organic ligands has been investigated, where Cp is the eta(5)-C5H5 ligand. The synthesis, single-crystal X-ray structure and physical/spectroscopic characterization are reported for the product [V(Cp)(2)(H2O)(2)](CF3SO3)(2)center dot THF (1 center dot THF). The coordination about the V-IV atom, formed by the two H2O molecules and the centroids of the cyclopentadienyl rings, is distorted tetrahedral. The [V(Cp)(2) (H2O)(2)](2+) cation is connected to the triflate anions via hydrogen bonds. Magnetic susceptibility, EPR and IR data are discussed in terms of the nature of bonding and the structure of the complex. (C) 2012 Elsevier B. V. All rights reserved.
