A new zinc phosphonate Zn(H2O)PO3–C13H9·H2O with a columnar structure was synthesized in hydrothermal conditions. This compound crystallizes in space group P21/c [a = 15.832(4) A, b =5.1915(10) A, c = 17.519(4) A and β = 114.479(6)°]. Its inorganic framework consists of isolated chains of corner-sharing ZnO3(H2O) and PO3C tetrahedra. These chains are linked to fluorene cycles, forming hybrid columns
在水热条件下合成了一种具有柱状结构的新型膦酸锌Zn(H2O)PO3–C13H9·H2O。该化合物在空间群 P21/c [a = 15.832(4) A, b =5.1915(10) A, c = 17.519(4) A 和 β = 114.479(6)°] 中结晶。其无机骨架由共角 ZnO3(H2O) 和 PO3C 四面体的孤立链组成。这些链与芴循环相连,形成混合柱,通过 C–H……π 键相互连接。这种混合材料的光致发光特性表明,它的发射带相对于母膦酸的发射带发生红移。这种效应是基于无机锌膦酸盐链施加的结构限制来解释的。
