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…     

Synthesis and Crystal Structure of a Two—dimensional Polymeric Holmium

The title polymeric complex [Ho(H2saln)1.5(NO3)3](H2saln=N,N'-bissalicyclidene-ethylenediamine) C24H24N6O12Ho was prepared and its crystal was characterized by X-ray diffraction. The ligand is dischiff base from salicylaldehyde and ethylenediamine. The complex crystallizes in trigonal system, space group Pc1(No. 165), Mr=753.42, a=15.818(2), c=16.978(3) , V=3681(2) 3, Dx=1.360 g/cm3, Z=4, μ=2.2286 mm-1, F(000)=1492, R=0.049, Rw=0.061. In the complex the coordination number of Ho(Ⅲ) is 9 with the geometry of a tricapped trigonal prism. All of the coordination atoms are oxygen atoms. The Ho(Ⅲ) ions are bridged by the dischiff base to form an infinite two-dimensional polymeric network, parellel to the (001) plane.
