Pentafluorophenylphosphine complexes of platinum(II); crystal structure of trans-[PtCl2(PEt3){PPh2 (C6F5)}]
Abstract
The reactions between the pentafluorophenylphosphines

3-x
(x = 0–2) and the dimeric
platinum(II) species
[{Pt(PEt

}] (x = 0 1, 1 2 or 2 3). The molecular
structure of complex 3 has been determined by single-crystal X-ray
crystallography, it crystallizes in the triclinic space group
