“…In continuation of our interest on the antimony(III) [41–43] and bismuth(III) [44, 45] complexes with aminopolycarboxylate ligands, we report herein a novel antimony-based heterometallic complex [Sb 2 (edta) 2 - μ 4 -Er(H 2 O) 4 ]NO 3 ·4H 2 O; its composition and crystal structure have been characterized by elemental analyses, FTIR spectrum, single crystal X-ray diffraction, and thermal analysis. The complex has been evaluated for its antimicrobial activities by agar diffusion method.…”

The novel 3D edta-linked heterometallic complex [Sb2Er(edta)2(H2O)4]NO3·4H2O (H4edta = ethylenediaminetetraacetic acid) was synthesized and characterized by elemental analyses, single-crystal X-ray diffraction, powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermal analysis. The complex crystallizes in the monoclinic system with space group Pm. In the complex, each erbium(III) ion is connected with antimony(III) ions bridging by four carboxylic oxygen atoms, and in each [Sb(edta)]− anion, the antimony(III) ion is hexacoordinated by two nitrogen atoms and four oxygen atoms from the edta4− ions, together with a lone electron pair at the equatorial position. The erbium(III) ion is octacoordinated by four oxygen atoms from four different edta4− ions and four oxygen atoms from the coordinated water molecules. The carboxylate bridges between antimony and erbium atoms form a planar array, parallel to the (1 0 0) plane. There is an obvious weak interaction between antimony atom and oxygen atom of the carboxyl group from the adjacent layer. The degradation of the complex proceeds in several steps and the water molecules and ligands are successively emitted, and the residues of the thermal decomposition are antimonous oxide and erbium(III) oxide. The complex was evaluated for its antimicrobial activities by agar diffusion method, and it has good activities against the test bacterial organisms.

Structural Diversity of Bismuth(III) Thiophenemonocarboxylates Isolated from Aqueous Solutions

et al. 2017

Five novel BiIII–thiophenemonocarboxylate (BiIII–TMC) compounds containing pyridinium cations have been synthesized from room‐temperature reactions of bismuth precursors with 2‐thiophenecarboxylic acid (HTMC) and pyridine in water. The structures have been determined by single‐crystal X‐ray diffraction, and two of the compounds have been further characterized by Raman spectroscopy and thermogravimetric analysis. The solid‐state structures of the compounds are built from anionic BiIII building units that vary in nuclearity, overall connectivity, and dimensionality. When using bismuth nitrate at a relatively low metal/ligand ratio, Hpy[Bi(TMC)4(HTMC)] (1) is formed, which consists of mononuclear units charge‐balanced by second coordination sphere pyridinium cations. With increasing metal/ligand ratios, and by consequence, increasing nitrate concentration, nitrate and carboxylate‐bridged chains of [Bi2(TMC)3(NO3)]– units in Hpy[Bi2(TMC)6(NO3)] (2), and nitrate‐bridged [Bi2(TMC)3(NO3)2]2– dimers in Hpy[Bi(TMC)3(NO3)] (3) are isolated. Starting from Bi2O3, polymorphs (Hpy)2[Bi2(TMC)8] (4) and (Hpy)2[Bi2(TMC)8] (5) are formed, both of which contain bismuth centers bridged by carboxylate groups to form dimeric units that are charge‐balanced by pyridinium cations. Presented herein is a discussion of the synthetic conditions over which 1–5 were isolated, and their solid‐state structural chemistry. The thermal stability of 1 and 3, and the spectroscopic characterization of the compounds, are also reported.
