Hydrothermal Syntheses and Characterizations of Two One-dimensional Molybdenum 1,4-Butylenediphosphonates

1 INTRODUCTION Interest in metal phosphonate chemistry has in- creased in recent years, not only because of their rich structural chemistry[1～3] but also owing to their potential applications in catalysis, absorption and intercalation reaction[4～6]. The introduction of a se- cond metal-ligand component as a charge-compen- sating unit and structure-directing component into polyoxomolybdenum/oxovanadium organodi-phos- phonates has provided us a powerful method to syn- thesize this family o…     

一个新的锡硫配合物(Et4N)[Sn2I6SOCH3]的合成、结构及量子化学研究

以锡粉、碘粉、硫粉和四乙基碘化铵为原料,在无水甲醇中,通过溶剂热反应合成了1个新的锡髧配合物(Et4N)[Sn2I6SOCH3]。对其进行了X-射线单晶衍射、元素分析的表征以及量子化学研究。该化合物属于单斜晶系,空间群为P21,a=0.728 65 nm,b=1.836 81 nm,c=1.016 25 nm,β=107.209°,V=1.299 2 nm3,Z=2。结构分析表明,化合物中的阴离子[Sn2I6SOCH3]-是由2个共边的SnSI3O三角双锥组成。电荷分布和前沿轨道的组成充分证实了配合物中配位键的存在。
