Abstract

In the title mononuclear complex, [Mn(C₁₄H₁₀NO₃)₂(CH₃OH)₄], the Mn^II atom, lying on an inversion centre, exhibits a distorted octahedral geometry, defined by two O atoms from two monodentate ligands and four O atoms from four methanol molecules. The crystal structure involves intramolecular O—H⋯N and O—H⋯O and intermolecular O—H⋯O hydrogen bonds.

Comment

General molecular mechanics method for transition metal carboxylates and the multiple coordination modes in manganese(II) complexes have been reported recently (Deeth, 2008). Information on the structures of manganese(II) carboxylates continues to be collected, and at the same time new applications of such complexes are being discovered in magnetic properties, potential biological significance and ferrimagnet (Huang et al., 2004). The chemistry of organo-manganese(II) complexes of Schiff base has stemmed from the reported biocidal and catalytic activities of organo-manganese(II) compounds (Dubois et al., 2008). We report here a new monomeric manganese(II) compound, which contains the Schiff base ligand, N-(4-carboxyphenyl)salicylideneimine (Fig.1). The Mn^II atom has a distorted octahedral geometry (Table 1). There exist intra- and intermolecular hydrogen bonds in the crystal structure (Table 2). The intermolecular hydrogen bonds is used to form a two-dimensional supramolecular network (Fig. 2).

Experimental

Manganese(II) acetate tetrahydrate (0.049 g, 0.2 mmol) was dissolved in 8 ml deionized water, giving a transparent solution (A), and N-(4-carboxyphenyl)salicylideneimine (0.097 g, 0.4 mmol) was dissolved in 10 ml me thanol (B). Then solution B was mixed with A and a suspension was obtained. Ammonia was added to the above mixture dropwise under magnetic stirring until pH value is neutral. The resulting suspension was transferred into a 25 ml Teflon-lined stainless-steel autoclave. The autoclave was sealed and maintained at 363 K for 12 h under autogenous pressure. After the reaction was completed, the resulting colourless block crystals were collected by filtration.
