Abstract

Two isostructural crown-like heteroselenometallic cluster compounds, [Et4N]4[(μ5-WSe4)(CuX) 5(μ-X)2] (X = Cl 1, Br 2), were prepared from the reactions of [Et4N]2[WSe4] with CuX and [Et4N]X• xH2O in the presence of 2-picoline and characterized by single-crystal diffraction analysis. The [(μ5- WSe4)(Cu-X)5(μ-X)2]4- anions in the cluster compounds consists of five CuX fragments coordinated to the five edges of the tetrahedral [WSe4]2- moiety along with two bridging halides connected to each of the two pairs of the symmetric copper atoms, exhibiting a novel crown-like core structure. The nonlinear optical absorption and refraction of cluster compound 2 were determined to be α2 = 6.15 × 10-10 m/W and n 2 = 4.18 × 10-11 esu, respectively.
