Carbonyl­(ferrocenyldi­phenyl­phosphine)(tropolonato)­rhodium(I)

The square-planar Rh^I complex, [Rh(trop)(PFcPh₂)(CO)] (tropH = 2-hydroxy-2,4,6-cyclo­heptatrienone, C₇H₆O₂, and PFcPh₂ = ferrocenyl­di­phenyl­phosphine, C₂₂H₁₉FeP), contains a five-membered chelate ring. The most important bond lengths and angles include Rh—O 2.0838 (14) Å (trans to P) and Rh—O 2.0487 (14) Å (trans to CO), Rh—P 2.2395 (5) Å, Rh—C 1.803 (2) Å, and O—Rh—O 77.56 (6)° and P—Rh—C 89.73 (7)°.
