Abstract

Reaction of trans-[(η⁵-C₅Me₅) ₂Mo₂(μ-S)₂S₂] (1) with 2 equiv of CuI in CH₂Cl₂ at ambient temperature or in refluxing MeCN afforded two isomeric clusters, [(η ⁵-C₅Me ₅)₂Mo₂(μ₃- S)₃S(CuI) ₂] (2) and [(η⁵-C₅-Me₅) ₂Mo₂(μ₃-S)₄(CuI)₂] (3). Compound 3 could also be prepared either by refluxing an acetonitrile solution of 2 or by heating 2 in the solid state at 120 °C. Compounds 2 and 3 were fully characterized by elemental analysis, IR, UV-vis, ¹H NMR, ESI-MS, and single-crystal X-ray crystallography. The molecular structure of 2 consists of an incomplete cubane-like core in which the trans structure of 1 was retained, while that of 3 contains a cubane-like core in which the trans structure of 1 was converted into the cis structure. The trans-to-cis isomerization from 2 to 3 either in solution or in the solid state was explored by means of ¹H NMR spectroscopy or X-ray powder diffraction. In addition, the third-order nonlinear optical (NLO) properties of 1-3 in CH ₂Cl₂ were investigated by using the Z-scan technique. The hyperpolarizability γ values for the two isomers (5.65 × 10 ^-30 esu (2) and 1.18 × 10^-29 esu (3)) are larger than that of their cluster precursor 1 (3.07 × 10^-30 esu).
