| Abstract: | The hydrothermal synthesis and X‐ray single crystal diffraction analysis of a novel three‐dimensional organo‐zincophosphite, HO(CH2)2NH3]2·Zn3(HPO3)4], are described. The framework is built up from strictly alternating vertex‐linked ZnO4 tetrahedron and HPO3 pseudo pyramid incorporating ethanolamine (EOA) cations into its channels. The structure is formed through ZnO4 tetrahedron connecting with two kinds of four‐membered ring chains along different directions. There are three intersecting channels with eight‐membered ring windows along 0 1 0], 0 4 15] and 0 – 4 15], which have not been found in organo‐zincophosphites before. Crystal data: HO(CH2)2NH3]2·Zn3(HPO3)4], Mr=640.21, Orthorhombic, Fdd2, a=2.8528 nm, b=0.8426 nm, c=1.6159 nm, Z=8, V=3.884 nm3, R1=0.0219, wR2=0.0544. |
