The title compound, [Mn(C5H7O2)2(C12H16N3O2)2], is isostructural with its NiII-containing analogue [Hao, Mu & Kong (2008). Acta Cryst. E64, m957]. The comprises one-half of the molecule and the MnII ion is located on an inversion centre. The coordination geometry around the MnII ion is slightly distorted octahedral, comprised of four O and two N atoms, in which the four O atoms in the equatorial plane come from two pentane-2,4-dionate ligands and the two N atoms in the axial coordination sites from 4,4,5,5-tetramethyl-2-(4-pyridyl)imidazoline-1-oxyl 3-oxide.

A mixture of Manganese(II) acetylacetonate (0.5 mmol) and 2-(4-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (1 mmol) in 20 ml methanol was refluxed for one day. The resulted solution was filtered. The filtrate was kept in the open flask and evaporated naturally at room temperature. Several days later, pink blocks of (I) were obtained with a high yield of ca 67% based on MnII. Anal. Calc. for C34H46MnN6O8: C 56.53, H 6.37, N 11.64%; Found: C 56.45, H 6.29, N 11.58%.
All H atoms were placed in calculated positions with C—H = 0.93 Å and C—H = 0.96 distances and refined as riding with Uiso(H) = 1.2 and 1.5 Ueq(carrier).

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. |

Due to the interesting structures from supramolecular assemblies as well as potential applications on smart optoelectronic, magnetic and porous materials, the design and synthesis of metal–organic coordination polymers have attracted considerable attention (Eddaoudi et al., 2000; Hye & Myunghyun, 1998; Li et al., 1999; Tabares et al., 2001). In this paper, we report the structure of the title compound, (I).
As shown in Fig. 1, the asymmetric unit comprises a half of the molecule and MnII ion locates on an inversion centre. The coordination geometry around MnII is slightly distorted octahedral, comprised of four O and two N atoms. In which, the four oxygen atoms in the equatorial plane come from two pentane-2,4-dionate and the two nitrogen atoms in the axial coordination sites from 2-(4-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide. The Mn—N and Mn—O bond lengths are in the range of 2.178 (2)–2.178 (2) and 2.0151 (17)–2.0386 (17) Å, respectively.
