Özet
A dimeric sodium supported borate complex, [Na(py)][B(hyncaH(-2))(2)](2) (1) (py = pyridine, hynca = 1-hydroxynaphthalene-2-carboxylic acid), has been synthesised by the reaction of NaBH4 with two equivalents of hynca in anhydrous THF and following crystallization from py/H2O solution afforded borate ester derivative. The complex has been fully characterized by FT-IR in the solid state and by NMR (H-1 and C-13) spectroscopy and electrospray ionization mass spectrometry in solution. The molecular structure of the title compound was determined by single crystal X-ray diffraction. Structure analysis of complex 1 confirmed the presence of an anionic complex [B(hyncaH(-2))(2)](-) in which boron atom is coordinated simultaneously by two hynca ligands utilising both alkoxide and carboxylate groups for bonding. The Na atom is six- coordinate to five O atoms of hydroxy carboxylic acid and one pyridine N atom. Crystal data: crystal system, monoclinic, a = 10.971(3) angstrom, b = 6.839(3) angstrom, c = 30.545(5) angstrom, beta = 92.20(2)degrees, space group P2(1)/c (#14), V = 2,290( 1) angstrom(3), Z = 4.
