Two novel 3-D oxalate-containing bismuth compounds of formula (C{sub 3}N{sub 2}H{sub 5}){sub 2} [Bi{sub 2}(C{sub 2}O{sub 4}){sub 4}(H{sub 2}O){sub 2}].2H{sub 2}O 1 and [NH(C{sub 2}H{sub 5}){sub 3}][Bi{sub 3}(C{sub 2}O{sub 4}){sub 5}] 2 were obtained by hydrothermal synthesis and characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic P2/n space group with a=9.7541(13)A, b=17.7404(15)A, c=14.6321(6)A, {beta}=97.280(3){sup o}, Z=4, R{sub 1}=0.0340 and wR{sub 2}=0.0766 for unique 4734 reflections I>2{sigma}(I). Compound 2 belongs to the orthorhombic Pbcn space group with a=14.803(4)A, b=19.783(7)A, c=8.202(2)A, Z=4, R{sub 1}=0.0222 and wR{sub 2}=0.0568 for unique 2472 reflections I>2{sigma}(I). The Bi{sup III} centers have nine-fold coordination for 1 and eight-fold for 2 with the Bi atoms in distorted monocapped square antiprism and distorted dodecahedron, respectively. And oxalate ligands adopt different coordination modes: bidentate for 1, bidentate and tricoordinate for 2. Compounds 1 and 2 are both 3-D open-framework structures containing channels with guest molecules. These two compounds exhibit intense blue luminescence with the emission peaks at 419nm for 1 and 442nm for 2, respectively, in the solid state at room temperature. These compounds with novel structural frameworks could be useful in the field of photoactive materials.
