文摘
Using multiethylenemultiamine to direct the crystallization of inorganic frameworksthrough multipoint hydrogen bonds, two new oxovanadium borophosphates, denoted VBP-J1 and VBP-J2, have been synthesized by hydrothermal methods as well as under refluxconditions. Powder X-ray diffraction patterns indicate that VBP-J1 and VBP-J2 are structuralanalogues. Structure determinations show that both VBP-J1, [H3NC2H4NH2C2H4NH2C2H4NH3]4H[NH4(VO)12{O3POB(O)2OPO3}6]·14H2O and VBP-J2, [H3NC2H4NH2C2H4NH2C2H4NH3]4H[K(VO)12{O3POB(O)2OPO3}6]·16H2O crystallize in the orthorhombic space group Pbcawith crystal data: a = 21.454(11) Å, b = 16.315(6) Å, c = 29.651(12) Å,

VBP-J1 and VBP-J2 are constructedby edge-sharing {V2O10} binuclear unit and {BP2O10} trimer to form interesting 12-memberring crown-shaped clusters with NH4+ and K+ cations encapsulated in the clusters. Thering diameters are 5.873 × 5.412 × 5.561 Å for VBP-J1 and 5.758 × 5.421 × 5.236 Å forVBP-J2. An extended network of multiple hydrogen bonds among anions, cations, and watermolecules links the structure in three dimensions.
