The reaction of the novel mixed tripod ligands RCH2C(CH2X)(CH2Y)(CH2Z) 1–6 (X, Y, Z=PPh2, NR2, pyrazol-1-yl; R=H, OH) with [RhI(COD)Cl]2 is investigated. The resulting rhodium COD complexes [(1–6)Rh(COD)]PF6, 7 are characterized by NMR spectroscopy, mass spectra and elemental analysis. In addition, X-ray structure analysis is performed on several compounds 7, where in contrast to the behavior of the
