Synthesis and Crystal Structure of aNovelPolythiotungstate Compound[PPh4]2[（S）2W（μ—S）2（O）W（THF）（μ—S）2W（S）2]

1 INTRODUCTION Polythiotungstate complexes can be prepared from the protonation of one sulfur atom of [WS4]2－ and subsequent intramolecular redox reactions[1,2]. For example, [(S)2W(m-S)2W(m-S)2W(S)2]2 was formed by the acidification of a diluted aqueous solution of (NH4)2[WS4] with dilute H2SO4[3]. When a diluted aqueous solution containing [WS4]2 was acidified with 0.1mol/L HCl, [(S)2W(m-S)2(O)- W(H2O)(m-S)2W(S)2]2 was formed[4]. [(S)2W- (m-S)2(S)W(m-S)2W(S)2]2 was form…

Synthesis,Crystal Structure and Characterization of a New Mixed-valence Cu（Ⅰ）/Cu（Ⅱ） Complex [Cu（bipy）（Me2dtc）CuI2]n

A new one-dimensional mixed-valence Cu(Ⅰ)/Cu(Ⅱ) complex [Cu(bipy)(Me2dtc)CuI2]n 1 (bipy = 2,2′-bipyridine and Me2dtc = N,N-dimethyldithiocarbamate) has been synthesized under solution condition, and characterized by elemental analysis, IR spectrum, single-crystal X-ray diffraction and magnetic property. The crystal belongs to the tetragonal system, space group P4122 with a = b = 11.6504(16), c = 13.466(3) , V = 1827.8(5) 3, Z = 4, Dc = 2.389 g/cm3, Mr = 657.27, λ(MoKa) = 0.71073 , μ = 5.931 mm·1, F(000) = 1236, the final R = 0.0483 and wR = 0.1245. A total of 2102 unique reflections were collected, of which 2009 with I > 2σ(I) were observed. 1 consists of polymeric [CuII2]nnanions and [CuII(bipy)(Me2dtc)]+ cations. It is interesting that the cations of 1 interact through π-π stacking interactions after rotating 90° to form one-dimensional chains parallel to the anion chains. The magnetic study indicates antiferromagnetic behavior for this complex.

Synthesis and Crystal Structure of the Polymorphic Isomer [Cu（dafone）2（H2O）2]（Hphth）2

1 INTRODUCTION The metal-containing supramolecular frame- works can be constructed through coordinate cova- lent or supramolecular contacts such as hydrogen- bond and π-π stacking[1 ～ 3]. Extended networks possessing higher dimensionalities can be obtained by assembly of coordination polymers (or comple- xes) with lower dimensionalities via hydrogen bond interactions[4～13]. However, normally the higher di- mensional networks are generated by one-dimen- sional chains through hydrogenbo…
