The heteronuclear {mu}-methylene {mu}-phenyl complexes CP{sub 2}Ti({mu}-CH{sub 2})({mu}-p-(CH{sub 3}){sub 2}NC{sub 6}H{sub 4})Rh(1,5-COD) (3b) (1,5-COD = 1,5-cyclooctadiene) and Cp{sub 2}Ti({mu}-CH{sub 2})({mu}-o-MeOC{sub 6}H{sub 4})Rh(1,5-COD) (3c) were synthesized from Cp{sub 2}Ti({mu}-CH{sub 2})({mu}-Cl)Rh(1,5-COD) (1) and the appropriate aromatic lithium reagent. Thes tructure of 3b was determined by single-crystal X-ray crystallography. The two metal atoms are bridged by the {mu}-methylene carbon remaining from 1 and by ipso carbon of the p-(N,N-dimethylamino)phenyl group. Compound 3b crystallizes in the triclinic system, in space group P{bar 1} (No. 2), with a = 8.988 (1) {angstrom}, b = 10.169 (1) {angstrom}, c = 13.707 (2) {angstrom}, {alpha} = 102.85 (1){degree}, {beta} = 103.47 (1){degree}, {gamma} = 101.36 (1){degree}, V = 1,146.2 (2) {angstrom}{sup 3}, and Z = 2. The structure was solved and refined with a final R = 0.0370 by using 3,882 independent reflections. Complex 3c was shown to have a similar structure by spectroscopic comparison to 3b.
