摘要：
The pentanuclear cluster complex (NEt4)(2)[MoS4(CuBP)(4)] has been prepared in acetone as a new candidate for nonlinear optical activity. The NLO properties of the cluster were studied, giving n(2) = -4.2 x 10(-11) esu and beta = 2.2 x 10(-10) m W-1. The structure of the complex has been determined by single-crystal X-ray diffraction. The coordination environment around each copper atom is distorted tetrahedral with two N donors of the bidentate bis(pyrazolyl)borate ligands and two S donors of the MoS4 group, offering a structural model for some copper proteins. The Mo atom retains the tetrahedral geometry of the free [MoS4](2-) anion and lies on a position with crystallographic S-4 symmetry. (c) 2006 Elsevier Ltd. All rights reserved.
