Abstract
The substitution of two carbonyl groups by a dppm ligand in the comple x [{(CO)(4)CoAu}(2)(dppm)] (1) cuses permutation in the metal skeleton sequence, giving the novel complex [Co2Au2(CO)(6)(mu-dppm)(2)] (3) ch aracterized by X-ray crystallography. Crystals of 3 are monoclinic, sp ace group Cc with unit cell parameters of a = 18.834(1) Angstrom, b= 1 6.257(1) Angstrom, c= 20.366(2) Angstrom, beta = 112.350(3)degrees, Z= 4, and V=6235(11) Angstrom(3). A mechanism for the formation of 3 is s uggested.
