(Received 1 March 2011; accepted 21 March 2011; online 26 March 2011)

In the title complex, [Mn(CH3CO2)2(C11H9N5)], the MnII atom is coordinated by the pyridine N atom and two pyrazole N atoms from a 2,6-bis­(pyrazol-3-yl)pyridine ligand and four O atoms from two bidentate acetate ligands. The complex mol­ecules are linked by inter­molecular N—H⋯O hydrogen bonds into a chain along [010]. ππ inter­actions between the pyridine rings and between the pyrazole rings [centroid–centroid distances = 3.772 (2) and 3.546 (2) Å] connect the chains.

Experimental top

2,6-Bis(pyrazol-3-yl)pyridine (0.1 mmol) was dissolved in methanol (2.5 ml) with 0.2 mmol of trimethylamine. Mn(OAc)2 (0.2 mmol) in methanol (2.5 ml) was added into the resulting solution. After stirring at room temperature for 1 h, the resulting yellow solution was put into a tube layered with aether. Yellow crystals were obtained in three days.

Refinement top

H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 (aromatic), 0.96 (CH3) and N—H = 0.86 Å and with Uiso(H) = 1.2(1.5 for methyl)Ueq(C, N).
