(Received 27 June 2011; accepted 21 July 2011; online 30 July 2011)

In the crystal structure of the title compound, [MnCl2(C14H14N4)2]n, the MnII atom, lying on an inversion center, is coordinated by four N atoms from four 1,4-bis­(imidazol-1-ylmeth­yl)benzene (bimb) ligands and two Cl− anions in a distorted octa­hedral geometry. The bimb ligands bridge the MnII atoms, forming a two-dimensional polymeric complex, which is composed of a 52-membered [Mn4(bimb)4] ring with distances of 7.7812 (2) and 27.4731 (9) Å between opposite metal atoms. Weak C—H⋯π inter­actions are present in the crystal structure.

Comment top

The supramolecular coordination assemblies are of great interest not only for their variety of architectures but also for the potential applications as functional materials (Maspoch et al., 2007; Ockwig et al., 2005). Many nitrogen-containing ligands have been successfully employed in the construction of the coordination compounds due to they can satisfy and even mediate the coordination needs of the metal center and consequently generate more meaningful architectures, in which supramolecular contacts (hydrogen bonding, π-π stacking) frequently occur (Zang et al., 2006; Zhang et al. 2009). To further explore various factors that influence the formation of result structures in the assembly reactions, we undertake synthetic and structural studies on one novel Mn(II) coordination polymers based on the highly flexible bidentate ligand 1,4-bis(imidazol-1-ylmethyl)-benzene (1,4-bimb): [Mn(bimb)2Cl2]n).

The metal-ligand connectivity pattern of complex is depicted in Figure 1. There are one kind of Mn(II) ion, one kind of Cl- and two kinds of bimb ligands in the structure. Metal center displays a symmetrical Cl2N4 octahedral geometry, and the related bond distances and bond angles are all symmetrically equivalent. Four N atoms from different bimb ligands comprise the equatorial plane, while two Cl- occupy the axial positions. Each bimb ligand acts as a µ2-bridge in trans-conformation with the planes of the two imidazole rings parallel. As shown in Figure 2, two rows of Mn(II) cations are linked together through bimb ligands to form a meso-helix running along the a-axis. Adjacent meso-helixes are associated together by sharing metal ions to form a two-dimensional architecture, in which large 52-membered rings [Mn4(bimb)4] with the opposite Mn···Mn distances being 7.7812 (2) Å and 27.4731 (9) Å are detected. If the metal center is considered as a four-connected node, the individual two-dimensional network can be described as a (4,4)-net. Further investigation shows that C8—H8···Cl1i hydrogen bonding is contribute to the stability of the layer. Neighboring layers are arranged parallel with the coordinated Cl- closed to H2 atoms of imidazole ring from adjacent layer, and interlayer C2—H2···Cl1ii hydrogen bonds can be detected which lead to the formation of the three-dimensional supromolecular structure, as shown in Figure 3. The hydrogen-bonding geometry is listed in Table 1.

Experimental top

1,4-Bis(imidazol-1-ylmethyl)-benzene (bimb) was prepared according to the literature (Hoskins et al., 1997), all other starting materials were of analytical grade and obtained from commercial sources without further purification. The title compound was synthesized hydrothermally in a Teflon-lined stainless steel container by heating a mixture of 1,4-bis(imidazol-1-ylmethyl)-benzene (bimb) (0.0119 g, 0.05 mmol), MnCl2.4H2O (0.0099 g, 0.05 mmol) and NaOH (0.0040 g, 0.1 mmol) in 7 ml of distilled water at 120°C for 3 days, and then cooled to room temperature. Yellow block crystals were obtained in 68% yield based on manganese.

Refinement top

H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93 Å, Uiso(H) = 1.2Ueq(C) for aromatic H, and C—H = 0.97 Å, Uiso(H) = 1.2Ueq(C) for CH2.

Special details top

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.
