Abstract top

In the centrosymmetric dinuclear title compound, [Mn2Cl4(C15H14N4)2(H2O)2], the MnII atom is coordinated by an N,N'-bidentate ligand, a water molecule, a terminal chloride ion and two bridging chloride ions in a distorted MnN2OCl3 octahedral geometry. The Mn...Mn separation is 3.6563 (9) Å. In the crystal structure, O-H...N and O-H...Cl hydrogen bonds help to establish the packing.

Comment top

The 1,2,4-triazole ring can act as a bidentate ligand in coordination chemistry (e.g. Klingele et al., 2005; Kume et al. 2006). We report here the synthesis and crystal structure analysis of the title compound, (I).

The structure of (I) is shown in Fig.1. The title compound is a centrosymmetric dinuclear maganese(II) complex bridged by two chloride ions (Table 1). The dihedral angle between the triazole and pyridine rings is 9.42 (24)°, and that between the triazole and benzene rings is 80.53 (12)°. In the crystal, O—H···N and O—H···Cl hydrogen bonds (Table 2) help to establish the packing.

Experimental top

To a warm solution of 0.501 g of 3-ethyl-4-phenyl-5-(2-pyridyl)-1,2,4-triazole (2.0 mmol) in 10 ml ethanol, 0.792 g of manganese(II) chloride tetrahydrate (4.0 mmol) in 10 ml water was added. The filtrate was left to stand at room temperature for several days, and pale yellow blocks of (I) were collected.

Refinement top

The H atoms were gemoetrically placed (C—H = 0.93–0.97Å, O—H = 0.85Å) and refined as riding with Uiso(H) = 1.2Ueq(carrier) or 1.5Ueq(methyl C).

Special details top

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
