Abstract

Five novel compounds were synthesized and characterized. Crystal structures were determined using Rigaku Mercury 375/MCCD(XtaLAB mini) diffractometer with graphite monochromated MoKα radiation. The crystal structures of [Rh₂(NPhCOCH₃)₄•xNCC₆H₄R where x = 1 or 2 and R=H, 2-CH₃,3-CH₃ and 4-CH₃ were solved to an R₁ value of less than 5 (R₁= Σ||F_o| - |F_c|| / Σ |F_o|). In each of the nitrile complexes, the rhodium is five or six coordinate and possesses pseudo D_4h symmetry. The complexes were also characterized by NMR and IR spectroscopy. [Rh₂(CO₂CCH₃)(PhCOCF₃)₃] was also synthesized. In this complex, each rhodium atom is six coordinate, thus each rhodium is in an octahedral environment. Details of each synthesized complex are discussed.
