Abstract: A novel supramolecular sodium N,N-piperazinebis(methylenephosphonate) Na2[(HO3PCH2)·NC4H8N(CH2PO3H)](H2O)8·2H2O, self-assembled into infinite1D chains, was synthesized by the reaction of N,N-piperazine bis(methylenephosphonic acid) with NaOH. Its structure was characterized by single crystal X-ray diffraction, ICP and elemental analysis. The compound crystallizes in triclinic system, space group P1 with a=0.659 06(2) nm, b=0.726 73(2) nm, c= 1.158 25(4) nm, α=79.751(2)°, β=75.833(2)°, γ=74.122(2)°, V=0.513 68(3) nm3, Z=2, Dc=1.611 Mg/m3, μ=0.331 mm-1, F(000)=264, S=1.098, R1=0.045 2, wR=0.136 0. In the crystal, edge sharing octahedron Na2O10 dimers and tetrahedron PO3C are assembled to an 1D chain via the bridges of heterocycle. 3D supramolecular framework is self-assembled from 1D chains through H-bonds.

Key words: Sodium N,N-piperazine bis(methylenephosphonate), Supermolecule, Single crystal structure
