catena-Poly[[bis(2-hydroxy-2-phenylacetato-κ²O¹,O²)zinc(II)]-μ-1,2-di-4-pyridylethane-κ²N:N′]

Abstract

The title compound, [Zn(C8H6O3)2(C12H12N2)]n, consists of [Zn(Hopa)2] (H2opa = 2-hydr­oxy-2-phenyl­acetic acid or mandelic acid) units bridged by 1,2-di-4-pyridylethane (bpe) ligands, forming a polymeric chain developing parallel to the b axis. The bridging bpe ligand is arranged around a twofold axis passing through the middle of the ethane C—C bond. The geometry around the ZnII ion is distorted octa­hedral, constructed by four O atoms from two Hopa− ligands and two N atoms from two bridging bpe ligands. O—H⋯O hydrogen bonds link the chains, forming a three-dimensional network.

“…acids and humic acids, mainly found in soil, is being extensively investigated. As models to examine these interactions we have previously used copper(II) and zinc(II) benzoates as building blocks and reported the structures of copper(II) and zinc(II) benzoates with quinoxaline, 6-methylquinoline, 3-methylquinoline, di-2-pyridylketone, andtrans-1-(2pyridyl)-2-(4-pyridyl)ethylene (Lee, et al, 2008;Yu, et al, 2008;Park, et al, 2008;Shin, et al, 2009;Yu, et al, 2009;Song, et al, 2009). The related paddle-wheel type structures for Zn complexes have been previouly reported (Necefoglu, et al, 2002;Zeleňák, et al,2004;Kamakar, et al, 2006;Ohmura, et al, 2005).…”

“…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.…”
