Abstract

The new RhzCu mixed-metal clusters [Rh2 (v-C5H5) 2 (p-CO) b-dppm) b-CuX)](X= C1, 2; X= I, 3; dppm= bis (dipheny1phosphino) methane) have been prepared by reacting [Rh2 (v- C5H,),(p-C0)(pdppm)](1) with CuX and have been spectroscopically characterized. The structure of 3 has also been established by X-ray crystallography. The compound cr stallizes in the orthorhombic space group Pnma with a= 14.002 (2) A, b= 18.306 (2) A, c= 13.025 (1 ...
