Formation and Crystal Structure of a Cationic Mono(cyclopentadienyl) Complex of Calcium, [(C5Me5)Ca(OPPh3)3]+I

Formation and Crystal Structure of a Cationic Mono(cyclopentadienyl) Complex of Calcium, [(C5Me5)Ca(OPPh3)3]+I

When the neutral Lewis base triphenylphosphine oxide reacts with (C5Me5)CaI(thf)2 in THF, the halide is displaced from the calcium to generate the stable cation [(C5Me5)Ca(OPPh3)3]+. The latter exhibits a “piano stool” geometry and displays only modest air sensitivity.

description When the neutral Lewis base triphenylphosphine oxide reacts with (C5Me5)CaI(thf)2 in THF, the halide is displaced from the calcium to generate the stable cation [(C5Me5)Ca(OPPh3)3]+. The latter exhibits a “piano stool” geometry and displays only modest air sensitivity.
