新型一维多酸化合物Sr_4H_2[Bi_2W_(20)Mn_2O_(70)(H2O)_6]·22H_2O的合成和表征

Synthesis and characterization of new 1D polyoxometalate Sr_4H_2[Bi_2W_(20)Mn_2O_(70)(H_2O)_6]·22H_2O

在水溶液中通过Na12[Bi2W22O74(OH)2]·44H2O,MnSO4和SrCl2反应得到了一个基于[Bi2W20Mn2O70(H2O)6]10-和Sr2+的新型一维多酸化合物Sr4H2[Bi2W20Mn2O70(H2O)6]·22H2O。X-单晶衍射分析表明该化合物中[Sr(H2O)3]2+单元、[Sr(H2O)7]2+单元和[Bi2W20Mn2O70(H2O)6]10-离子分别作为二、一和六连接点。

A new 1D polyoxometalate compounds Sr4H2[Bi2W20Mn2O70（H2O）6]·22H2O based on the [Bi2W20Mn2O70 （H2O）6]^10-and Sr^2＋ions was synthesized by the reaction of Na12[Bi2W22O74（OH）2]·H2O, MnSO4,and SrCl2 in aqueous solution. X-ray diffraction analysis reveals that the [Sr（H2O）3]2＋unit, [Sr（H2O）7]^2＋unit and [Bi2W20Mn2O70（H2O） 6]^10-anion in the compound Sr4H2[Bi2W20Mn2O70（H2O）6]·22H2O act as two-connected, one connected and ten connected nodes, respectively.
