摘要：

A re-investigation of the reaction of Au(PPh(3))Cl with [Fe(CO)(4)](2-) has shown that the [Fe(CO)(4)(AuPPh(3))](-) monoanion and [Fe(CO)(4)(AuPPh(3))(2)] are obtained in sequence by using a 1:1 and 2:1 molar ratio, respectively. The complex [Fe(CO)(4)(AuPPh(3))(2)] crystallizes in the monoclinic space group P2(1)/a, a=20.309(5), b=18.379(3), c=40.737(6) Angstrom, beta=96.26(2)(0), Z=16, R=0.0526. There are four crystallographically independent but chemically equivalent molecules in the asymmetric unit. Each molecule consists of an Au2Fe triangle with the two Au atoms bearing a PPh(3) ligand and the iron atom bound to four carbonyl groups. The feature of greatest interest in this molecule is the Au-Au interaction whose length is found in the range 2.897-2.941(1) Angstrom, quite different from that quoted from a previous study (3.028(1) Angstrom).
