|Abstract:||A novel dimolybdenum complex in which the metal atoms are bridged by two different chalcogens and two thiolato ligands has been synthesised and structurally characterised. This complex shows a large third-order optical nonlinearity as measured by degenerate four-wave mixing with picosecond excitation at 532 nm. A hyperpolarisability (gamma) of 1.2 x 10(-30) esu has been obtained. The structure of the complex was established by the single-crystal X-ray diffraction method. It consists of a Mo-Mo unit, which is bridged by one S, one Te and two (SPh) groups. Each Mo atom also has a (eta(5)-C5H5) group attached to it. (C) 2000 Elsevier Science S.A. .|
