The title compound Cs[(VO)2(OH)(O3PCH2CH2PO 3)] 1 was synthesized hydrothermally from a mixture of CsVO3, H2O3PCH2CH2PO3H 2, and H2O in the mole ratio 1 : 1.22 : 535 and heated to 200°C for 48 hr. Phosphonate 1 is formed in 45% yield and crystallizes in the monoclinic space group P21/c witha=11.798(2) Å,b=11.056(2) Å,c=8.682(2) Å,β=104.92(3)°,V=1094.3(4) Å3,Z=4, andR=0.054. The framework consists of complimentary inorganic V/P/O layers joined by ethylenediphosphonate ligands, creating an inorganic bilayer. The bilayers are seperated by an interlamellar region of Cs+cations. There are two unique VO5square pyramids from which the inorganic V/P/O layers are constructed.
