Abstract:

Two novel 3-D oxalate-containing bismuth compounds of formula (C3N2H5)(2) [Bi-2(C2O4)(4)(H2O)(2)](.)2H(2)O 1 and [NH(CH5)(3)] [Bi-3(C2O4)(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) angstrom, b = 17.7404(15) angstrom, (.)c = 14.6321(6) angstrom, beta = 97.280(3)degrees, Z = 4, R-1 = 0.0340 and wR(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)angstrom, b = 19.783(7) angstrom, c = 8.202(2) angstrom, Z = 4, R-1 = 0.0222 and wR(2) = 0.0568 for unique 2472 reflections I > 2 sigma(I). The Bi-III centers have ninefold coordination for I 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 I 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 419 nm for 1 and 442 nm 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. (c) 2006 Elsevier Inc. All rights reserved.
