Abstract: The molecular structure of[(η5-MeO2CC5H4)(CO)2MO][(η5-MeO2CC5H4)(CO)2W] Fe(CO)3(μ3-S), prepared through isolobal displacement reaction between η5-MeO2CC5H4)(CO)3MONa and [(η5-MeO2CC5H4)(CO)2W]Fe(CO)3Co(Co)3 (μ3-S) has been determined by X-ray diffraction technique.The crystal belongs to triclinic space group P1 with α=0.87162(5) nm,b=0.76218(4) nm,c=1.87111(8)nm,α=94.164(4)°,β=97.979(2)°γ=99.108(2)°,Z=2,μ=5.9cm-1.The final agreement factor R=0.036 for 4180 observed reflectional points.There is a tetrahedral MoWFeScluster core in the molecule of this complex with Mo and Woccupying two apexes disorderly in the ratio of 1:1.
