Abstract

The terdentate ligands C6H3-2,6-(CH(2)PCy(2))(2) (PCP: Cy = cyclohexyl) in the octahedral solvento complexes trans-[RhCl2(MeOH)(PCP)] and trans-[RhCl2(EtOH)(PCP)] adopt conformations which minimise the interactions between the sterically demanding Cy groups and the trans chlorides. Comparison of these structures with those of related molecules, including square-pyramidal and square-planar species, suggests an explanation for the different structural types obtained as products from reactions of RhCl3.3H(2)O and various ligands C6H4-1,3-(CH(2)ER(2))(2) with E = N or P.
