Abstract

In the title compound, [MnCl(C₁₀H₁₂N₂O)(H₂O)₃]Cl, the Mn^II ion has a distorted octahedral coordination environment formed by one N and one O atom from the chelating 3-dimethylamino-1-(2-pyridyl)prop-2-en-1-one ligand, one chloride anion and three coordinated water molecules. Intermolecular O—H⋯O and O—H⋯Cl hydrogen bonds link the cations and anions into layers parallel to the ac plane.

Comment

We have taken many efforts on synthesizing new ligands with pyridyl group and reported a monomeric Cd (II) complex using 3-dimethylamino-1-(4-pyridyl-)prop-2-en-1-one as ligand (Dong et al., 2009). Here we obtain an analogous ligand, 3-dimethylamino-1-(2-pyridyl-)prop-2-en-1-one by similar method, and report a new Mn (II) complex, viz. the title compound, [Mn(C₁₀H₁₂N₂O)(H₂O)₃Cl]⁺.Cl^- (I).

In (I) (Fig. 1), the Mn^II center shows an octahedral coordination geometry formed by NO₄Cl. Cholride anions are involved in formation of O—H···Cl hydrogen bonds (Table 1), which link cations and anions into layers parallel to ac plane along with the intermolecular O—H···O hydrogen bonds (Table 1).

Experimental

Ligand was prepared following the procedure reported in the literature (Sun et al., 2008). A solution of the ligand (0.1 mmol) and MnCl₂ (0.1 mmol) in 40 ml of methanol was refluxed for 2 h, and then cooled to room temperature and filtered. Single crystals suittable for X-ray analysis were grown from the methanol solution by slow evaporation at room temperature in air. Anal. Calcd. for C₁₀H₁₈MnN₂O₄Cl₂: C, 33.72; H, 5.09; N, 7.87. Found: C, 33.68; H, 5.13; N, 7.83.
