[NH3(CH2)6NH3][P2V5O17]·3.83H2O: A new 3D Organic‐templated Vanadophosphate with Extra‐large 16‐Membered Ring Constructed from Nanosized P–O–V Wheels

A new porous 3D vanadophosphate, [NH3(CH2)6NH3][P2V5O17]·3.83H2O (1) is synthesized by using NH2(CH2)6NH2 as template, and characterized by single crystal structural analysis, X-ray diffraction, IR spectroscopy, TG analysis, and powder XRD. Single crystal analysis shows that compound 1 crystallizes in cubic shape, space group Imm with cell dimensions: a = b = c = 26.5068(8) A, V = 18624.0(10) A3, Z = 24. Structural refinement indicates that the inorganic framework of 1 is constructed from nanosized P–O–V wheels.
