Synthesis and Crystal Structure of [MoOS_3Cu_3I(dmpzm)_2]·2(MeCN)_(0.5) (dmpzm=Bis(3,5-dimethylpyrazolyl)methane)

1 INTRODUCTION The synthesis of molybdenum-copper-sulfur clus- ters from the preformed clusters with certain nitro- gen donor ligands remains attractive due to their rich chemistry and electro/photonic properties[1~6]. How- ever, the third-order nonlinear optical performances of these Mo/Cu/S clusters have been limited due to their relatively low solubility in common organic solvents[5]. One possible way to tackle this problem is to introduce bulky organic ligands into the cluster framew…

Synthesis and Crystal Structure of a Hydrogen-bonded Supramolecular Compound [(C_6H_5N_2O)_3·Cu_1._5]·6H_2O

1 INTRODUCTION The binding of metal ions by proteins and pep- tides is of fundamental interest due to the impor- tance of metal ions in biological systems. Metals may be part of the active sites of enzymes, stabilize the macromolecular structure of proteins and affect enzymes or membranes to control cell metabolism[1]. Therefore, for many years there has been a great in- terest in the study of complexes able to mimic these active sites of metalloproteins. In this case, metal complexes of…

簇合物[(η5-C5Me5)WS3{Cu(PPh3)}3Cl](PF6)的合成及晶体结构

Reaction of a preformed cluster [{(η⁵-C₅Me₅)WS₃}₃Cu₇(MeCN)₉](PF₆)₄ (1) in MeCN with LiCl and PPh₃ gave rise to a tetranuclear cationic cluster [(η⁵-C₅Me₅)WS₃{Cu(PPh₃)}₃Cl](PF₆) (2). The title compound 2 was characterized by elementary analysis, IR, UV-Vis, ¹H NMR, and its crystal structure was determined by X-ray single crystal diffraction. It belongs to monoclinic, space group P2₁/c with a=1.799 8(4) nm, b=2.083 6(4) nm, c=1.913 5(4) nm, β=113.63(3)°, V=6.574(3) nm³, Z=4. The cluster cation [(η⁵-C₅Me₅)WS₃{Cu(PPh₃)}₃Cl]⁺ of 2 contains a strongly distorted, cubane-like structure [WS₃Cu₃Cl] in which one Cl weakly fills into the void of the nido-like [WS₃Cu₃] fragment with three relatively long Cu-Cl distances.

Synthesis and Crystal Structure of Cubane—typeMolybdenum Cluster ComplexMo4S4（DTP）4[μ—SOP（OEt）2]2

1 INTRODUCTION Trinuclear molybdenum complexes with Mo3(3-S)(-O)n(-S)3n (n = 0~3) cores have been extensively studied on their diversified reactions towards various organic ligands and many metals. Many derivatives with Mo3S4 core have been rationally synthesized from the cation precursor [Mo3S4(H2O)9]4+ and its neutral derivative Mo3(3-S)(-S)3(DTP)4(H2O)[1]. However, due to their structural lability, complexes with Mo3(3-S)(-O)n(-S)3n (n = 1~3) cores have been reported limitedl…
