Abstract

In the polymeric title complex, [Mn(C₉H₉O₂S)₂(C₁₀H₈N₂)(H₂O)₂]_n, the Mn²⁺ cation and the 4,4′-bipyridine ligand lie on a twofold rotation axis. The cation has an MnN₂O₄ octahedral environment, being coordinated by the O atoms of two water molecules and two monodentate (4-tolylsulfanyl)acetate anions, and by two N atoms of two 4,4′-bipyridine ligands. The latter bridge adjacent cations into linear chains parallel to [010]. The chains are further linked with each other into a two-dimensional network parallel to (100) via intermolecular O—H⋯O hydrogen bonds.

Comment

The title complex, (I), is isotypic with the Ni²⁺ (Lin et al., 2006), Co²⁺ (Zheng et al., 2006) and Cd²⁺ analogues (Cai et al., 2008).

The structure of (I) (Fig. 1) consists of linear polymeric chains parallel to [010]. The chains are formed through 4,4'-bipyridine ligands bridging the Mn²⁺ cations. The latter are in a slightly distorted MnN₂O₄ octahedral coordination environment defined by four O atoms of pairs of water molecules and monodentate (4-tolylsulfanyl)acetate anions. Intermolecular O—H···O hydrogen bonding between the water molecules and the carboxylate O atoms link neighboring chains into a two-dimensional network parallel to (100).

In comparison with the isotypic structures, the structural parameters are very similar; as expected, the metal—N and metal—O bond lengths differ slightly due to the differences of the ionic radii of Cd²⁺, Co²⁺, Mn²⁺ and Ni²⁺.

Experimental

Mn(CH₃COO)₂^.4H₂O (0.132 g, 0.5 mmol), (4-tolylsulfanyl)acetic acid (0.091 g, 0.5 mmol), 4,4'-bipyridine (0.039 g, 0.25 mmol) and water (18 ml) were sealed in a 25 ml Teflon-lined stainless-steel reactor. The solution was heated at 433 K for 72 h and then cooled to room temperature over a period of 72 h. Yellow crystals suitable for X-ray analysis were obtained.
