Preliminary communicationTri(1-cyclohepta-2,4,6-trienyl)PHOSPHAN (cas 115-78-6)-komplexe des rhodiums(I) und iridiums(I)☆

Highly symmetrical complexes MCl[P(C7H7)3] (M = Rh (3a), Ir (3b); point symmetry C3v) have been synthesized which contain tri(1-cyclohepta-2,4,6-trienyl)phosphane (1) as a tetradentate tripod ligand. According to the X-ray structure analysis of 3a, the metal occupies the center of a trigonal bipyramid with Cl and P in the axial positions and three double bonds forming the equatorial plane. Chloride abstraction from 3a by AgBF4 leads to Rh[P(C7H7)3]+BF−4 (6a).
