A novel 3-D compound of (enH{sub 2}){sub 1.5}[Bi{sub 3}(C{sub 2}O{sub 4}){sub 6}(CO{sub 2}CONHCH{sub 2}CH{sub 2}NH{sub 3})].6.5H{sub 2}O has been hydrothermally synthesized and characterized by IR, ultraviolet-visible diffuse reflection integral spectrum (UV-Vis DRIS), fluorescence spectra, TGA and single crystal X-ray diffraction. It crystallizes in the monoclinic system, space group C2/c with a=31.110(8)A, b=11.544(3)A, c=22.583(6)A, {beta}=112.419(3){sup o}, V=7497(3)A{sup 3}, Z=8, R{sub 1}=0.0463 and wR{sub 2}=0.1393 for unique 7686 reflections I>2{sigma}(I). In the title compound, the Bi atoms have eight-fold and nine-fold coordination with respect to the oxygen atoms, with the Bi atoms in distorted dodecahedron and monocapped square antiprism, respectively. The 3-D framework of the title compound contains channels and is composed of linkages between Bi atoms and oxalate units, forming honeycomb-like layers with two kinds of 6+6 membered aperture, and pillared by oxalate ligands and monamide groups. The channels have N-ethylamine oxalate monamide group {sup -}CO{sub 2}CONHCH{sub 2}CH{sub 2}NH{sub 3}{sup +}, which is formed by the in situ reaction of en and oxalate acid. At room temperature, the complex exhibits intense blue luminescence with an emission peak at 445nm.
