Rh2(O2CCH3) 4·2C≡NC6H4R (R = (CH3)2N-(1), -H (2), -CF3 (3)) were synthesized and characterized by X-ray crystallography. The structures exhibited several common features: (i) a relatively short Rh-C bond (2.148(4) A? (1), 2.133(4) A? (2), and 2.122(4) A?(3)), (ii) an inversion center between the two rhodium atoms, (iii) coplanar aryl rings, and (iv) a significant deviation from linearity in the Rh-C-N bond angle. Comparison to other rhodium carboxylate complexes indicates the presence of π-back-bonding and, by extension, π-back-bonding in rhodium-carbenoid systems.
