Abstract
A new open framework of rare earth organic compounds, {Ho2(BDOA)3(H2O)2}n, is hydrothermally synthesized and structurally determined by X-ray single-crystal diffraction. The compound belongs to triclinic space group P1, cell parameters: a=0.60912(12)nm, b=1.0636(2)nm, c=1.3477(3)nm, α=96.66(3), β=96.574(1)°, γ=97.64(3), V=0.789.3(3)nm3, Z=1, Dc= 3.938mg/m3, R1=0.0471, R2=0.0524, the minimum and maximum residual peak for 2955 And -1721 e/nm3. The Ho is bridged by BDOA, leading to 3D openframework.
