Abstract

The synthesis and crystal structure of the first example for hybrid Sn-Mo tetranuclear cubane-like cluster compound containing S/O mixed triple capping atom [Mo3(SnBr3)(μ 3-O)(μ 3-S)3(dtp)3(py)3]·(CH2Cl2) (A) (dtp=S2P(OC2H5)2) are reported. The compound is prepared by the reaction of [Mo3(μ 3-O)(μ-S)3(dtp)4·(H2O)] with SnBr 3 . The molecular structure of the cluster can be described as a [Mo3OS3] core with the SnBr 3 fragment linked to {Mo3} triangle by three (μ 3-S). Three Mo-Mo bond lengths are 2.616(2), 2.620(2), 2.628(2) Å, respectively, and the molecule has approximately C3v symmetry. There is no bonding between Sn and Mo atoms, however, the addition of SnBr 3 may cause electron transfer from Sn2+ to [Mo3OS3] core to result in the shortening of Mo-Mo bond distances. The compound crystallizes in the monoclinic space group P21/n with refined lattice parameters ofa=13.012(4),b=22.877(6),c=18.585(6) Å,β=96.34(3)°,V=5498(3)Å3, andZ=4. Full matrix refinement converged with final agreement factor ofR=0.054,R w=0.064.
