Abstract

A novel trinuclear hekzakis(mu(6)-2-benzoylbenzoato-O,O')-bis(3-picoline)-tri-zinc(II) complex, [Zn-3(bba)(6)(3-pic)(2)] 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 mu-2-benzoylbenzoato-O,O' bridges. The crystal packing of the trinuclear complex is stabilized by C-H center dot center dot center dot pi interaction between bba ligands. The characteristics of the carboxylate anions with typical nu(OCO)(asym) and nu(OCO)(sym) values are 1594 and 1368 cm(-1), respectively.
