The reaction of bcpmCr2(CO)6 (bcpm = biscyclopentadienylmethane) with sulfur gives in a stepwise reaction the complexes bcpmCr2(CO)4S (2) and bcpm2Cr4S4 (3). The products were investigated by IR and low temperature H-1 NMR spectroscopy. The H-1 NMR spectra of 2 show upon cooling a dynamic process similar to that in the starting material. It is ascribed to a topomerization process in the bridging ligand. The cluster 3 which belongs to the heterocubane type exhibits a magnetic behavior which is inbetween that of the antiferromagnetic clusters of type CP4Cr4O4 (CP = any substituted eta-5-C5H5 ring) and the diamagnetic CP4Cr4S4 cubanes.
