Abstract top

The title compound, [Mn(C11H11N2O3)2(H2O)2], consists of discrete mononuclear complex molecules. The MnII atom is located on an inversion center and coordinated by two N atoms and two O atoms, each pair in a trans mode, from two 3-(2-hydroxyethyl)-2-methyl-4-oxopyrido[1,2-a]pyrimidin-9-olate ligands and by two water molecules. The coordination geometry around the MnII atom is slightly distorted octahedral. Molecules are linked by O-H...O hydrogen bonds into a three-dimensional network.

Comment top

In the past decade, much attention has been paid to the design and synthesis of self-assembling systems with organic ligands containing N and O donors (Bayot et al., 2006; Chen et al., 2007). Quinolin-8-ol is such a ligand and the crystal structure of a complex containing it has been reported (Wu et al., 2006). We report here the synthesis and crystal structure of the title compound.

In the title compound (Fig. 1), the MnII atom is located on a crystallographic inversion center and adopts a distorted octahedral coordination geometry. The coordination environment is defined by two N atoms and two O atoms from two ligands in the equatorial plane and by two water molecules in the axial positions (Table 1). Intermolecular O—H···O hydrogen bonds involving the hydroxyl groups and water molecules as donors connect the molecules into a three-dimensional network (Table 2; Fig. 2).

Experimental top

Manganese carbonate (0.028 g, 0.1 mmol) was added with constant stirring to a ethanol solution (10 ml) containing 3-(2-hydroxyethyl)-2-methyl-9-hydroxylpyrido[1,2-a]pyrimidin-4-one (0.022 g, 0.1 mmol). The mixture was then filtered off. After a few days, brown single crystals in the form of rectangular blocks deposited. They were separated off, washed with cold ethanol and dried in air at room temperature.

Refinement top

H atoms bound to C atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 (aromatic), 0.97 (CH2) and 0.96 Å (CH3) and Uiso(H) = 1.2(or 1.5 for methyl)Ueq(C). H atoms of hydroxyl group and water molecule were located in a difference Fourier map and refined isotropically, with a restraint of O—H = 0.82 (1) Å for the hydroxyl group.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
