The 2(C6H6O7)2(H2O)4]·C12H12N2·2H2O, comprises half of a centrosymmetric dimer, half of a 1,2-bis(pyridin-4-yl)ethane and one water molecule. Two citrate ligands bridge two MnII ions, the MnII ion being coordinated by four O atoms from the citrate(2−) ligands and two water O 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 which is further stabilized by intermolecular π–π interactions [centroid–centroid distance = 3.792 (2) Å].

Citric acid (19.4 mg,0.1 mmol) and Mn(NO3)2.H2O(18.3 mg, 0.1 mmol) were dissolved in 4 ml H2O and carefully layered by 4 ml acetonitrile solution of 1,2-bis(pyridin-4-yl)ethane (38.0 mg, 0.2 mmol). Suitable crystals of the title compound were obtained in a month.
H atoms bonded to C atoms were placed in calculated positions with C—H distances of 0.93 Å for aromatic C atoms and 0.97 Å for methylene C atoms. They were included in the
in riding-motion approximation with Uiso(H) = 1.2Ueq(C). H atom bonded to O atom was placed in the calculated position with O—H distance of 0.82 Å for carboxylate O atom, and it was included in the in riding-motion approximation with Uiso(H) = 1.5Ueq(C). The position of O—H atom of the hydroxyl group was refined with O—H = 0.93 Å and Uiso(H) = 1.5Ueq(N). The positions of O—H atoms of the coordinated water ligands were refined with O—H = 0.86 Å and Uiso(H) = 1.2Ueq(N). The positions of O—H atoms of the free water molecule were refined with O—H = 0.96 Å and Uiso(H) = 1.2Ueq(N).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), we have intensively studied the interaction of the transition metal ions with the various acids such as benzoic acid, citric acid, and amino acids. Therefore, we have reported a variety of structures of copper(II), cadmium(II), nickel(II), cobalt(II), and zinc(II) benzoates with quinoxaline, 6-methylquinoline, 3-methylquinoline, trans-1-(2-pyridyl)-2-(pyridin-4-yl)ethylene, and di-2-pyridyl ketone (Lee, et al., 2008; Yu, et al., 2008; Park, et al., 2008; Shin, et al., 2009; Song, et al., 2009; Yu, et al., 2008, 2009; Kim, et al., 2011). However, manganese as a metal π-π interactions [centroid = C11–C15/N11; centroid–centroid distance = 3.792 (2) Å symmetry code: 1-x, -y, 2-z ].
was rarely used. In this work, we have employed manganese(II) nitrate as a building block and citric acid as a ligand. We report here on the structure of new tetraaquadicitratodimanganese(II)-1,2-bis(pyridin-4-yl)ethane-dihydrate, [Mn2(H2O)4(C6H8O7)2].(C12H12N2).2(H2O). The molecular structure of the title compound is shown in Fig. 1. The of the title compound, C24H36Mn2N2O20 , comprises half of a centrosymmetric dimer , half of a 1,2-bis(pyridin-4-yl)ethane ligand and one water molecule. Two citrate ligands bridge two MnII ions, and each MnII is coordinated by four oxygen atoms from the citrates ligand and two water oxygen atoms, forming a distorted octahedral environment. In the crystal, O—H···O hydrogen bonds link the cetrosymmetric dimer and free H2O components into a three-dimensional structure.

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. |

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), we have intensively studied the interaction of the transition metal ions with the various acids such as benzoic acid, citric acid, and amino acids. Therefore, we have reported a variety of structures of copper(II), cadmium(II), nickel(II), cobalt(II), and zinc(II) benzoates with quinoxaline, 6-methylquinoline, 3-methylquinoline, trans-1-(2-pyridyl)-2-(pyridin-4-yl)ethylene, and di-2-pyridyl ketone (Lee, et al., 2008; Yu, et al., 2008; Park, et al., 2008; Shin, et al., 2009; Song, et al., 2009; Yu, et al., 2008, 2009; Kim, et al., 2011). However, manganese as a metal ion source was rarely used. In this work, we have employed manganese(II) nitrate as a building block and citric acid as a ligand. We report here on the structure of new tetraaquadicitratodimanganese(II)-1,2-bis(pyridin-4-yl)ethane-dihydrate, [Mn2(H2O)4(C6H8O7)2].(C12H12N2).2(H2O). The molecular structure of the title compound is shown in Fig. 1. The asymmetric unit of the title compound, C24H36Mn2N2O20 , comprises half of a centrosymmetric dimer , half of a 1,2-bis(pyridin-4-yl)ethane ligand and one water molecule. Two citrate ligands bridge two MnII ions, and each MnII is coordinated by four oxygen atoms from the citrates ligand and two water oxygen atoms, forming a distorted octahedral environment. In the crystal, O—H···O hydrogen bonds link the cetrosymmetric dimer and free H2O components into a three-dimensional structure. The crystal structure is further stabilized by intermolecular π-π interactions [centroid = C11–C15/N11; centroid–centroid distance = 3.792 (2) Å symmetry code: 1-x, -y, 2-z ].
