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.
