The title complex, [Mn2(C8H7O3)4(C12H8N2)2]·0.5CH3OH, is a carboxylate-bridged dinuclear MnII complex with four phenoxyacetate ions and two 1,10-phenanthroline molecules as ligands. Each of the four phenoxyacetate anions bridges the pair of Mn atoms. The is completed by a half-occupancy methanol solvent molecule. Face-to-face π–π stacking interactions between the aromatic rings of 1,10-phenanthroline molecules belonging to adjacent Mn2 complexes, with an interplanar separation of circa 3.4 Å, and weak C—H⋯O hydrogen bonds connect the dinuclear units into a three-dimensional supramolecular framework.

[Mn3O(O2CCH2OPh)6(pyridine)2(H2O)] was synthesized according to the literature method of Sessoli et al., (1993). To a solution of [Mn3O(O2CCH2OPh)6(pyridine)2(H2O)] (0.15 mmol 0.18 g) in MeCN (8 ml) and CH3OH (2 ml), powdered 1,10-phenanthroline (0.15 mmol 0.030 g) was added. The resulting solution was stirred for 0.5 h., filtered and layered with two volumes of Et2O. After two weeks, light brown crystals of (I) were collected by filtration, washed with Et2O, and dried in vacuo. The yield was approximately 20%.
Carbon-bound H atoms were positioned geometrically, with C—H = 0.97 Å for methylene groups, 0.93 Å for aromatic groups, and 0.96 Å for the methyl groups of MeOH. They were refined using a riding model, with Uiso(H) = 1.2Ueq(carrier C) for the complex and Uiso(H) = 1.5Ueq(C57) for the MeOH molecule. The hydroxyl H atom H13a was positioned geometrically and freely refined. Occupancy for the methanol molecule was refined in preliminary cycles and fixed to 1/2 for final
Finally, geometry for phenyl ring C1···C6 was constrained by fitting the six C atoms to a regular hexagon with C?C bond lengths of 1.39 Å.The rational design, synthesis and characterization of novel supramolecular frameworks are currently of great interest. One of the greatest challenges in this area is the construction of porous materials from metal ions and organic ligands as building blocks (Yaghi et al., 1997). As part of our search for new porous metal-organic frameworks, we are studying complexes of transition metals with phenoxyacetate ligands (Jiang et al., 2005, 2006). Here, the title compound, (I), a novel dinuclear MnII complex with 1,10-phenanthroline as co-ligands, is reported.
Complex (I) exists as a dinuclear unit, with four bidentate phenoxyacetate anions bridging the pair of MnII atoms (Fig. 1). Two N atoms from 1,10-phenanthroline molecules bind to the MnII atoms, and both MnII atoms thus possess a distorted octahedral coordination geometry. The
is completed by 1/2 methanol solvate. The Mn—O distances are in the range 2.087 (2) to 2.351 (3) Å, and the average distance for Mn—N bonds is 2.31 Å. The planes of two coordinated phenanthroline molecules are set approximately perpendicular to each other.Interestingly, The Mn2 units further link to each other into a microporous framework (Fig. 2) by π-stacking from the plane of 1,10-phenanthroline of symmetry-related molecules and C—H···O hydrogen bond interactions between alternating molecules. These supramolecular interactions are illustrated in Fig. 3. The C—H···O hydrogen bonds that exist in the peripheral ligands of adjacent Mn2 complexes are formed via the H donor atoms from phenyl group and acceptor O atoms of OCH2 groups of phenoxyacetate ligands. It is noteworthy that the contacts are almost linear (C—H···O: 174.9°). The structural significance is that the dipole-monopole and dipole-dipole contributions to electrostatic energy are maximum at 180° and zero at 90°. Therefore, this interaction may be considered as an efficient C—H···O hydrogen bond.
The overall three-dimensional supramolecular structure is also stabilized by significant offset face-to-face π···π stacking interactions between the aromatic rings of 1,10-phenanthroline molecules belonging to adjacent Mn2 complexes, with an interplanar separation of ca 3.4 Å and θ = 21.9° (Fig. 3).

The rational design, synthesis and characterization of novel supramolecular frameworks are currently of great interest. One of the greatest challenges in this area is the construction of porous materials from metal ions and organic ligands as building blocks (Yaghi et al., 1997). As part of our search for new porous metal-organic frameworks, we are studying complexes of transition metals with phenoxyacetate ligands (Jiang et al., 2005, 2006). Here, the title compound, (I), a novel dinuclear MnII complex with 1,10-phenanthroline as co-ligands, is reported.
Complex (I) exists as a dinuclear unit, with four bidentate phenoxyacetate anions bridging the pair of MnII atoms (Fig. 1). Two N atoms from 1,10-phenanthroline molecules bind to the MnII atoms, and both MnII atoms thus possess a distorted octahedral coordination geometry. The asymmetric unit is completed by 1/2 methanol solvate. The Mn—O distances are in the range 2.087 (2) to 2.351 (3) Å, and the average distance for Mn—N bonds is 2.31 Å. The planes of two coordinated phenanthroline molecules are set approximately perpendicular to each other.
Interestingly, The Mn2 units further link to each other into a microporous framework (Fig. 2) by π-stacking from the plane of 1,10-phenanthroline of symmetry-related molecules and C—H···O hydrogen bond interactions between alternating molecules. These supramolecular interactions are illustrated in Fig. 3. The C—H···O hydrogen bonds that exist in the peripheral ligands of adjacent Mn2 complexes are formed via the H donor atoms from phenyl group and acceptor O atoms of OCH2 groups of phenoxyacetate ligands. It is noteworthy that the contacts are almost linear (C—H···O: 174.9°). The structural significance is that the dipole-monopole and dipole-dipole contributions to electrostatic energy are maximum at 180° and zero at 90°. Therefore, this interaction may be considered as an efficient C—H···O hydrogen bond.
The overall three-dimensional supramolecular structure is also stabilized by significant offset face-to-face π···π stacking interactions between the aromatic rings of 1,10-phenanthroline molecules belonging to adjacent Mn2 complexes, with an interplanar separation of ca 3.4 Å and θ = 21.9° (Fig. 3).
