(Received 8 November 2012; accepted 15 November 2012; online 24 November 2012)

The asymmetric unit of the title compound, [Mn2(C6H6O7)2(H2O)4]·C12H10N2·2H2O, contains half of the centrosymmetric Mn complex dimer, half of a 1,2-bis­(pyridin-4-yl)ethene mol­ecule, which lies across an inversion center, and one water mol­ecule. Two citrate ligands bridge two MnII ions, and each MnII atom is coordinated by four O atoms from the citrate ligands (one from hy­droxy and three from carboxyl­ate groups) and two water O atoms, forming a distorted octa­hedral environment. In the crystal, O—H⋯O and O—H⋯N hydrogen bonds link the centrosymmetric dimers and lattice water mol­ecules into a three-dimensional structure which is further stabilized by inter­molecular ππ inter­actions [centroid–centroid distance = 3.959 (2) Å]. Weak C—H⋯O hydrogen bonding interactions are also observed.

Complexes involving citric acid have often been used as models to examine the interaction between transition metal ions with biologically active molecules (Daniele et al., 2008; Parkin, 2004; Tshuva & Lippard, 2004; Stoumpos et al., 2009). Quite recently, our group has reported two novel compounds from the reaction of manganese(II) and zinc(II) nitrates as the building blocks and citric acid as the ligand (Hwang, et al., 2012a,b). In order to study the effects of spacer ligands on the interaction between transition metal ions with citric acid (Yu, et al., 2009; Kim, et al., 2011), in this work, we have attempted to employ 1,2-bis(4-pyridyl)ethene as a spacer source. We report here the resulting structure in which the 1,2-bis(4-pyridyl)ethene molecule does not function as a spacer but co-crystallises with the Mn complex to form bis(µ-2-carboxymethyl-2-hydroxybutanedioato)bis[diaquamanganese(II)]– 1,2-bis(pyridin-4-yl)ethene–water(1/1/2).

The molecular structure of the title compound is shown in Fig. 1. The asymmetric unit of the title compound, C24H34Mn2N2O20, contains half of the centrosymmetric Mn complex dimer, half of a 1,2-bis(pyridin-4-yl)ethene molecule, which lies across an inversion center, and one water molecule. Two citrate ligands bridge two MnII ions, and each MnII is coordinated by four oxygen atoms from the citrate ligands (one hydroxyl and three carboxylate, with one bridging) and two water oxygen atoms, forming a distorted octahedral environment. In the crystal, O—H···O hydrogen bonds link the centrosymmetric dimers and lattice water molecules into a three-dimensional structure. The crystal structure is further stabilized by intermolecular π-π interactions [centroid = C11–C15/N11; centroid–centroid distance = 3.959 (2) Å symmetry code: 1 - x, 2 - y, z].

Experimental top

Citric acid (19.4 mg, 0.1 mmol) and Zn(NO3)2.6H2O (30.4 mg, 0.1 mmol) were dissolved in 4 ml H2O and carefully layered by 4 ml of an acetonitrile solution of 1,2-bis(4-pyridyl)ethene (37.6 mg, 0.2 mmol). Suitable crystals of the title compound were obtained from this solution within two weeks.

Refinement top

H atoms bound to C were placed in calculated positions with C—H distances of 0.95 Å for aromatic C atoms and 0.99 Å for methylene C atoms. They were included in the refinement using the riding-motion approximation with Uiso(H) = 1.2Ueq(C). H atoms bound to O were located in difference Fourier maps and refined with their O–H distances restrained as follows and Uiso(H) = 1.2Ueq(O). Hydroxyl O—H = 0.860 (2) Å, coordinated water molecules O—H = 0.930 (2) Å the free water molecule O—H = 0.930 (2) Å.

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.
