چکیده
Thermolysis of a toluene solution containing [Fe2W(CO)10( 3-S)2] (1) and [( -C5H5)W(CO)3(CCPh)] (2), at 80°C yields the mixed metal cluster [Fe2(CO)6( 3-S)2W{( -C5H5)W(CO)3(CCPh)}2] (3). Structure of 3 has been established crystallographically. It consists of a triangular Fe2W unit, each face of which is capped by a sulfido ligand. Each Fe atom bears three carbonyl groups. Two separate molecules of [( -C5H5)W(CO)3(CCPh)] are attached to the W atom of the Fe2W core through the acetylide groups.

Reaction of Fe3(CO)12 with 1,2-dithiolene HSC6H2Cl2SH affords a mixture of complexes [Fe2(CO)6(μ-SC6H2Cl2S)] 1, [Fe2(SC6H2Cl2S)4] 2 and [Fe3(CO)7(μ3-SC6H2Cl2S)2] 3. In the course of the reaction the trimetallic cluster 3 is first formed and then converted into the known dinuclear compound 1 to afford finally the neutral diiron tetrakis(dithiolato) derivative 2. Compounds 2 and 3 have been studi...
