trans-Rh(CO)(Cl)(Br)(CCl3)[P((CH2)14)3P] (11c, 97%) or trans-Rh(CO)2(I)[P((CH2)14)3P] (12c, ∼98%). The crystal structures of 5c, 6c, 8c, and 10c are determined. These and other data are used to calculate the dimensions of the rotators and void spaces of the diphosphine cages, aiding the interpretation of dynamic properties. Specifically, 4c–6c and 9c–10c exhibit a single set of seven CH213C NMR signals at room temperature
