Abstract
Reaction of Cp2Cr2(SCMe3)2S (I) with Fe3S2(CO)9 gives the novel metallospirane cluster Cp2Cr2(μ-SCMe3)(μ3-S)2Fe(μ3-S)2Fe2(CO)6 (II). Analogous clusters with Co and Rh as central ions (III and IV respectively) have been obtained from the reaction of (MeC5H4)2Cr2(μ-SCMe3)(μ3-S)2Co(CO)2 or Cp2Cr2(μ-SCMe3)(μ3-S)2RhL2 (L = CO, L2 = COD) with Fe2(CO)6S2. The X-ray diffraction study of II (space group P1, a 9.691(4), b 12.294(3), c 14.515(5) A, α 66.25(2), β 74.89(3), γ 78.61(3)°, V 1519.8 A3, Z = 2) reveals Cr2Fe and Fe3 triangles in the Cr2FeFe2 metallospirane core at a dihedral angle of 106.8°, and the geometry of dichromium disulfide thiolate fragment remains unchanged as compared to I, III and IV (CrCr 2.689; 2.610(2); 2.598(2); 2.608(5) A in IIV, respectively). II has strong CrFe bonds (2.717(2) and 2.727(2) A, but the two bonds between the central and peripheral Fe atoms (3.018(2) and 3.032(2) A) are relatively weak. The peripheral FeFe bond (2.503(2) A) is still rather short. Formal replacement of the Fe atom in II by the Co atom in III (space group Pnam, a 14.549(2), b 14.480(2), c 14.146(2) A, V 2980.1 A3, Z = 4) results in the rupture of the FeFe bond (Fe…Fe 3.399(2) A) and formation of the two single CoFe bonds (2.554 (2) and 2.538(2) A). The dihedral angle between the planes of the metal triangles Cr2Co and CoFe2 in III is 90°. The geometry of the Rh(S)2Fe2(CO)6 moiety in the Rh-containing metall-spirane IV (space group P21/n, a 9.800(2), b 12.983(3), c 22.606(5) A, β 97.05(2)°, V 2854.3 A3, Z = 4) is not significantly different from that of the Co(S)2Fe2(CO)6 fragment in III (RhFe 2.650(4) A, Fe…Fe 3.344(4) A), the main difference involves the dihedral angle between the Cr2Rh and RhFe2 planes, which is 129.1° in IV. This difference being due to the tendency of the RhI atom to form the square planar complexes on one hand, and to decreasing the repulsion between the S atoms and the strengthening the RhCr bonds in the nonplanar ligand environment of the Rh atom on the other.
