Synthesis, Characterization, and Crystal Structures of a Novel [Zn 3(Bba)6(3-Pic)2] Complex (Bba = 2-Benzoylbenzoat, 3-Pic = 3-Picoline)

Abstract

A novel trinuclear hekzakis(μ<inf>6</inf>-2-benzoylbenzoato-O,O')-bis(3- picoline)-tri-zinc(II) complex, [Zn<inf>3</inf>(bba)<inf>6</inf>(3-pic) <inf>2</inf>] has been synthesized and characterized by elemental analysis, Fourier-transform infrared (FT-IR), ultraviolet/visible (UV/Vis), and mass spectroscopy, thermal methods, and single-crystal x-ray diffraction. The three Zn(II) centers are in two different coordination environments. The central Zn(II) is in a distorted octahedral geometry, while the two terminal Zn(II) centers adopt a distorted tetrahedral geometry. The central and the terminal metal centers are connected through tri μ-2-benzoylbenzoato-O,O' bridges. The crystal packing of the trinuclear complex is stabilized by C-H ⋯π interaction between bba ligands. The characteristics of the carboxylate anions with typical (OCO)<inf>asym</inf>and (OCO)<inf>sym</inf> values are 1594 and 1368 cm-1, respectively. Copyright © Taylor & Francis Group, LLC.
