Tetra-μ-benzoato-bis[(6-methylquinoline)copper(II)]

Abstract

In the title compound, [Cu2(C7H5O2)4(C10H9N)2], the paddle-wheel-type dinuclear complex is constructed by four bridging benzoate groups and two terminal 6-methyl­quinoline ligands. The asymmetric unit contains one-half of the whole mol­ecule, and there is an inversion center at the mid-point of the Cu⋯Cu bond. The octa­hedral coordination of each Cu atom, with four O atoms in the equatorial plane, is completed by the N atom of the 6-methyl­quinoline mol­ecule [Cu—N = 2.212 (2) Å] and by another Cu atom [Cu⋯Cu = 2.6939 (13) Å]. The Cu atom lies 0.234 Å out of the plane of the four O atoms. The molecular packing is stabilized by one intramolecular C—H⋯O as well as C—H⋯π and π–π interactions.

“…In attempting to model the interaction, we have extensively studied the interaction of the transition metal carboxylates e.g. copper(II), cadmium(II), and zinc(II) benzoates with a variety of spacers such as quinoxaline, 6-methylquinoline, 3-methylquinoline, trans-1-(2pyridyl)-2-(4-pyridyl)ethylene, and di-2-pyridyl ketone (Lee et al, 2008;Yu et al, 2008;Shin et al, 2009;Yu et al, 2009;Yu et al, 2010;Kim et al, 2011). However, nickel as a metal ion source has rarely been used.…”

“…The interaction of transition metal ions with biologically active molecules such as amino acids, proteins, sugars, and various acids is of great importance in biological systems (Daniele, et al, 2008;Parkin, 2004;Tshuva & Lippard, 2004;Stoumpos, et al, 2009). As models to examine the interaction, we have intensively studied the interaction of transition metal ions with various acids such as benzoic acid, fulvic acids and humic acids and have reported a variety of structures of copper(II), cadmium(II), and zinc(II) benzoates with quinoxaline,6-methylquinoline, 3-methylquinoline, trans-1-(2pyridyl)-2-(4-pyridyl)ethylene, and di-2-pyridyl ketone (Lee, et al, 2008;Yu, et al, 2008;Park, et al, 2008;Shin, et al, 2009;Song, et al, 2009;Yu, et al, 2008Yu, et al, ,2009Yu, et al, ,2010Kim, et al, 2011). In this work, we have employed nickel (II) chloride as a building block and quinaldic acid as a ligand.…”
