Hydrothermal syntheses and single crystal structural characterization of M(H2O)6(OPTA)2 [M = Co(II), Ni(II), Zn(II); OPTA = 1-oxopyridinium-2-thioacetato]

Abstract

A new class of compounds of the family M(H 2 O) 6 (OPTA) 2 (where M = Co(II), Ni(II), and Zn(II); OPTA = 1-oxopyridinium-2-thioacetato) was prepared from the appropriate metal acetates, 1-oxopyridinium-2-thioacetic acid (OPTAH), and potassium hydroxide in hydrothermal media and structurally characterized. The structure is constructed from M(H 2 O) 6 2+ and two anions of OPTAH (C 7 H 6 NO 3 S) linked through hydrogen bonding into an extended network.

“…The key step in the design of coordination polymers is to select suitable multidentate bridging ligands and spacers. Many pyridine-based carboxylate ligands (Kumaresan et al, 2006;Hussain, 1996;Fariati et al, 1998) have been used to obtain coordination polymers but, to the best of our knowledge, very little is known about the coordination chemistry of 1-oxopyridinium-2-thiopropionic acid, HOPTP (Ramasubramanian et al, 2007). The HOPTP ligand possesses several features.…”

Supramolecular network formed through O-H⋯O and π-π stacking interactions: Hydrothermal syntheses and crystal structures of M(H2O)6](optp)2 (M = Mg, Ni, Zn, and optp = 1-oxopyridinium-2-thiopropionate)

“…The coordination geometry of barium(II) ions in [Ba(μ-opta) 2 (H 2 O) 3 ] n ⋅3nH 2 O, was described as a distorted dodecahedron, 14 in which the opta anions and a water molecule were forming bridges between two Ba(II) ions whereas in transition metal complexes, the metal ions (cobalt, nickel and zinc) were coordinated only with six water molecules and have distorted octahedral geometry. 15 In this paper, we report the synthesis and structural characterization of simple ionic salt of type [M(H 2 O) 6 ](optp) 2 with magnesium, nickel and zinc cations.…”
