Abstract

<p>Bismuth carboxylates of the composition Bi(anth)(3)center dot Solv (1a: Solv = 0.5MeNO(2)center dot 0.5H(2)O, 1b: Solv = 0.5MeCN) were isolated from the reaction of BiPh3 with three equivalents of anthranilic acid (Hanth, 2-aminobenzoic acid) in nitromethane and acetonitrile, respectively. The composition of the soluble compounds 1a and 1b was established by NMR and infrared spectroscopy, and elemental analysis. The thermal behavior was evaluated by thermogravimetric analysis (TGA), and bismuth oxide and bismuth were observed as final decomposition products in air and helium, respectively. Both compounds 1a and 1b crystallize in the monoclinic space group P2(1)/n with formation of a one-dimensional coordination poly-mer of Bi-N-bridged dimers, which crystallize with non-coordinating solvent molecules to give [Bi(anth)(3)center dot Solv](infinity), as was shown by single-crystal X-ray diffraction analysis. The reaction of [Bi6O4(OH)(4)(NO3)(6)]center dot H2O with anthranilic acid resulted in the polynuclear bismuth oxido anthranilato nitrate [{Bi38O45(anth)(4)(NO3)(20)(DMSO)(24)}{Bi38O45(anth)(4)(NO3)(20)(DMSO)(24)}]center dot 6DMSO (2) upon crystallization from DMSO. Compound 2 crystallizes in the triclinic space group P (1) over bar with two crystallographically independent molecules in the asymmetric unit and represents the first example of a bismuth oxido cluster bearing anthranilate ligands.</p>
