The synthesis and structural characterization of a novel Bi-Mo double cubane cluster coupled by two bridging oxygen atoms {[Mo-3(BiI3)OS3(mu-OAc)(2)(py)(3)](2)(mu-O)(2)}center dot 2(H2O)

With [Mo-3(mu(3)-O) (mu-S)(3)(mu-OAc)(2)(dtp)(2)(py)](dtp = S2P(OC2H5)(2))( -); OAc = OOCCH3-; py = C5H5N) as the starting material, the reaction toget her with BiI3 in presence of (H2O) results in a novel Bi-Mo double-cubane c luster coupled by two bridging oxygen atoms {[Mo-3(BiI3)(mu(3)-O) (mu(3)-S) (3) (mu-OAc)(2)(py)(3)](2)(mu-O)(2)}. 2(H2O) 2. The cluster 2 has been char acterized by IR, Raman, UV-Vis, NMR and single-crystal X-ray study. A compa rison is made between these results and those of the previously reported si ngle cubane Bi-Mo cluster [Mo-3(BiI3) (mu(3)-S)(4)(mu-OAc) (dtp)(3)(py)] 1. (C) 1998 Elsevier Science Ltd.
