Abstract

In the title compound, [Zn₄(C₁₁H₉N₂O₂)₄(C₇H₅O₂)₄]·2(CH₃)₂CO·CH₃OH, the tetranuclear molecule lies on a fourfold inversion axis. Zn^II ions and μ₃-O atoms in the cubane core occupy alternating vertices, forming two interpenetrating tetrahedra. Each Zn^II ion is further coordinated by two N atoms from two different (py)₂C(OH)O ligands (py is pyridyl) and one O atom from a monodentate benzoate ligand, forming a distorted octahedral environment. The (py)₂C(OH)O ligand acts in an η¹:η³:η¹:μ₃ manner, forming two five-membered ZnNCCO chelating rings with two different Zn^II atoms sharing a common C—O bond, and an alkoxide-type bond to a third Zn^II ion. There are four symmetry-related intramolecular O—H⋯O hydrogen bonds between the two types of ligands. In the asymmetric unit, there is a half-occupancy acetone solvent molecule and a half-occupancy methanol solvent molecule that lies on a twofold rotation axis.

Comment

Transition metal ions have, recently, received attention as the major cationic contributors to the inorganic composition of natural water and biological fluids (Daniele, et al., 2008). While the main interest is focused on the interaction of transition metal ions with biologically active molecules such as amino acids, proteins, sugars and nucleotides, the study on the interaction of the transition metal ions with fulvic acids and humic acids, mainly found in soil, is in incipient stages. As models to examine the interaction, therefore, we have previously used copper(II) benzoate as a building block and reported the structures of copper(II) benzoates with quinoxaline, 6-methylquinoline, and 3-methylquinoline (Lee, et al., 2008; Yu, et al., 2008; Park, et al., 2008). In this work, we have employed zinc(II) benzoate as a building block and di-2-pyridyl ketone as a ligand. We report herein the structure of the product of zinc(II) benzoate with di-2-pyridyl ketone.

The crystal structure contains tetranuclear [Zn₄(O₂CPh)₄{(py)₂C(OH)O}₄] molecules (Fig. 1), similar to the corresponding Mn₄ cubane compound (Stoumpos, et al., 2008). The tetramolecular molecule lies on a fourfold inversion center and hence the asymmetric unit contains a quarter of a molecule. Zn^II ions and µ₃-O atoms in the cubane [Zn^II₄(µ₃-OR)₄]⁴⁺ core occupy alternate vertices. Thus, the molecule consists of two interpenetrating tetrahedra: one contains four µ₃-O atoms originating from the (py)₂C(OH)O ligands, and the other contains four Zn^II atoms. Each Zn^II center is coordinated by two N atoms from two different (py)₂C(OH)O ligands and one O atom from a monodentate PhCO₂^- ligand to form a distorted octahedral geometry. The (py)₂C(OH)O ligands acts as η¹:η³:η¹:µ₃ to form two five-membered ZnNCCO chelating rings with two different Zn^II ions sharing a common C—O edge and an alkoxide-type bond to a third Zn^II ion. This ligation mode is common for the hydrated di-2-pyridyl ketone, (py)₂C(OH)O^- (Papaefstathiou & Perlepes, 2002; Papatriantafyllopoulou,et al., 2007). There are intramolecular hydrogen bonds interactions between the protonated O atom of the (py)₂C(OH)O ligand and the uncoordinated O atom of the monodentate PhCO₂ group.

Experimental

38.0 mg (0.125 mmol) of Zn(NO₃)₂^.6H₂O and 35.5 mg (0.25 mmol) of C₆H₅COONH₄ were dissolved in 4 ml water and carefully layered by 4 ml solution of a mixture of acetone, methanol and ethanol (2/2/2) of di-2-pyridyl ketone ligand (46.1 mg, 0.25 mmol). Crystals of the title compound suitable for X-ray analysis were obtained in a few weeks.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
