The article conveys some information:
Structural modulation of transition metal carboxylates was studied by employing different auxiliary ligands in the reactions of metal acetates with substituted benzoic acids. Neutral transition metal benzoates [Cu(tbba)2(imH)2] (1), [Cu(tipba)2(2,4,6-collidine)2] (2), [Co(tbba)2(dmpH)2] (3), [Co(tipba)2(imH)2] (4), [M(tmba)2(pymeH)2] (M = Cu (5), Co (6) and Zn (7)), [Zn(tmba)2(pydmeH2)] (8), [Cu2(tmba)2(pydmeH2)2][(tmba)2(tmbaH)2] (9) and [Zn2(dmp)2(tbba)2(dmpH)2] (10) were isolated as products from the reaction between the resp. metal acetates and substituted benzoic acids (acids used: 4-tert-butylbenzoic acid (tbbaH), 2,4,6-triisopropylbenzoic acid (tipbaH), 2,4,6-trimethylbenzoic acid (tmbaH)) and N-donor auxiliary ligands (imidazole (imH), 3,5-dimethylpyrazole (dmpH), 2,4,6-collidine, 2-pyridinemethanol (pymeH), and pyridine-2,6-dimethanol (pydmeH2)). The new complexes were characterized by both anal. and spectroscopic methods. The mol. structures of 1-10 have further been established by single crystal x-ray diffraction studies. The complexes 1-8 are mononuclear, while compounds 9 and 10 are dinuclear due to the role of benzoic acid in 9 and pyrazolate anion as bridging ligand in 10. The geometry around the metal ion is square-planar in 1 and 2, tetrahedral in 3, 4 and 10, octahedral in 5-7 and 9 and trigonal-bipyramidal in 8. Complexes with ligands that contain addnl. functional groups such as >NH and -OH are involved in hydrogen bonding interactions. These weak interactions give 1-dimensional linear polymers or 2-dimensional sheets.2,6-Pyridinedimethanol(cas: 1195-59-1Name: 2,6-Pyridinedimethanol) was used in this study.
2,6-Pyridinedimethanol(cas: 1195-59-1) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.Name: 2,6-Pyridinedimethanol
