Reaction of salts of HFe(CO)3PR3- (R = OMe, OEt, OPh, Me, Ph) with Ph3PAuCl leads to quantitative partitioning into H2Fe(CO)3PR3 and (Ph3PAu)2Fe(CO)3PR3.The complex (Ph3PAu)2Fe(CO)3P(OEt)3*Et2O crystallized in the monoclinic space group P21/n, with a 10.385(3), b 35.452(10), c 13.648(6) Angstroem, V 5024(3) Angstroem3, β 91.15(3) deg, and Z = 4.The coordination geometry about Fe is that of a distorted Fe(CO)3PR3 tetrahedron bicapped with Ph3PAu moieties; one along a OC-Fe-CO edge and the other in a face at an Au-Fe-Au angle of 69.0(1) deg.The Au-Au bond distance of 2.872(2) Angstroem is the smallest observed for analogous group 8 (R3PAu)2M(CO)4 complexes and is less than the Au-Au distance of metallic gold.Acute Fe-Au-Au angles in the Au2Fe triangle of 54.7(1), and 56.3(1) deg further suggest a cluster formulation for the trimetallic.
