Hydrothermal synthesis and crystal structure of (H_2bpp)_3 [Mo_5P_2O_(23)]·H_2O: A twofold interpenetrating 3D supramolecular architecture constructed of Standberg-type polyoxometalate

摘要

A novel three-dimensional (3D) supramolecular assembly of Standberg-type polyoxometalate and flexible organic molecule (H_2bpp)_3[Mo_5P_2O_(23)]·H_2O (1) [bpp = 1,3-bis(4-pyridyl)propane] has been hydrothermally synthesized and structurally characterized by singlecrystal X-ray diffraction, IR spectra, elemental analysis and thermogravimetric analysis (TGA). X-ray analyses show that compound 1 represent a twofold interpenetrating 3D supramolecular architecture constructed of Standberg-type polyoxometalate and bpp molecular through the hydrogen bonds as well as electrostatic interactions.
