N2 - Syntheses of the array of heterobimetallic complexes [(OC)(3)M(mu-PPh2)(2)(mu-O-C(CHMe(CH2)(2)PPh2)RhL], M = Cr, Mo, W, L = (BuNC)-Bu-t, are described, extending the previous study of the counterpart array for L = CO. A single crystal X-ray structure determination is reported for the M = Mo adduct, enabling comparison with its previously reported L = CO counterpart, for which an improved redetermination is also reported. In the present complex the BuNC ligand is found to be much more weakly bound (Rh-C 2.026(5) angstrom) than the carbonyl group it displaces (Rh-C 1.945(2) angstrom) with concomitant minor impact on the remainder of the rhodium ambience.
