(Received 15 July 2009; accepted 23 July 2009; online 8 August 2009)

In the cation of the title compound, [Mn(C11H13N5)2](ClO4)2·CH3CN, the metal atom is located on a twofold rotation axis and is six-coordinated by six N atoms from two different 2,6-bis­(4,5-dihydro-1H-imidazol-2-yl)pyridine (bip) ligands in a distorted octahedral geometry. The O atoms of the perchlorate anions are disordered with occupancies in the ratio 0.593 (10):0.407 (10). In the crystal, mol­ecules are stabilized by two N—H⋯O hydrogen bonds, forming zigzag chains along the a axis, which are further inter­connected by N—H⋯O hydrogen bonds and π–π inter­actions [centroid–centroid distance = 3.50 (1) Å] into a three-dimensional network.

Comment top

The construction supramolecular architectures is currently of great interest owing to their intriguing network topologies and potential functions such as adsorption, ion exchange, shape-selective catalysis, non-linear and magnetic materials (Yaghi et al., 1998; Hagrman et al., 1999). The protonation and deprotonation of an imidazole ligand is believed to play an important role in the mechanism of the coordination chemistry (Bordo, et al., 2001). We described previously a number of such metal complexes, including imidazole ligand, and have concluded that hydrogen bonding involving this group influences the geometry around the metal atom and the crystallization mechanism (Ren, Ye, He et al., 2004; Ren, Ye, Zhu et al., 2004; Ren et al., 2007, 2009). We report here the preparation and crystal structure of a mononuclear coordination complex, [Mn(bip)2](ClO4)2.CH3CN (I) (bip is 2,6-bis(4,5-dihydro-1H-imidazol-2-yl)pyridine).

The crystal structure of (I) crystallizes in the monoclinic space group C2/c. As shown in Fig. 1, the title compound consists of a [Mn(bip)2]2+ cation, two perchlorate counter ions and one Acetonitride molecular. The manganese(II) atom in the cation is in a distorted tetrahedral geometry, being coordinated with six nitrogen atoms from two neutral tridentate ligands bip. The Mn(1)—N bond lengths of The equatorial 2.292 (4), 2.284 (4), 2.251 (4) Å, which are slightly shorter than the metal-imidazole (Stupka, et al., 2004; Hammes et al., 2005; Haga et al., 1996; Böca et al., 2005) and longer than the metal-imidazole (Ren, et al., 2009). The N—Mn(1)—N bond angle is in the range of 70.17 (15)–147.1 (2) /%. Two bip ligands of adjacent molecules are parallel to each other with a distance of 3.50 Å, showing the presence of π-π interaction. The molecules further interconnected into three-dimensional network through hydrogen bond between the oxygen atom of perchlorate counter-ion and the uncoordination nitrogen atoms of bip ligands.

Experimental top

All the reagents and solvents employed were commercially available and used as received without further purification. The ligand 2,6-bis(4,5-dihydro-1H-imidazol-2-yl)pyridine (bip) was synthesized by literature methods (Baker et al., 1991).

A solution of MnCl24H2O (0.2 mmol, 40 mg) and NaClO4 (0.4 mmol, 50 mg) in acetonitrile (10 ml), was added dropwise to a stirred solution of bip (0.4 mmol, 86 mg) in methanol(10 ml) at 60 K. Yellow single crystals suitable for X-ray diffraction were obtained by slow diffusion of diethyl ether into the clear filtrate for two days in 60% yield. Elemental analysis, Found: C, 39.68; H, 3.93; N, 21.15%. Calc. for C24H29Cl2MnN11O8: C, 39.70; H, 4.00; N, 21.23%. Main IR bands (KBr, cm-1): 3370m, 3204 s, 2938m, 2887m, 1595m, 1567 s, 1531 s, 1453 s, 1283 s, 1209w, 1144 s,1116 s, 1089 s, 1028w, 1010m, 953w, 830w, 752w, 663w, 636m, 628m.

Refinement top

The H atom attached to N(2) atom was refined isotropically. All the other H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms with N—H and C—H distances of 0.90 Å and 0.96 Å, respectively, and Uiso(H) = 1.2 times of those of their parent atoms (Å2). The O atoms are resolved into two positions by PART instructions. The occupancy for the unprimed O atoms is set at 21 and that of the primed atoms at -21. The clorine-oxygen distances were restrained to 1.44 Å (and the oxygen-oxygen interaction to 2.35 Å). Additionally, the vibration of the oxygen atoms were made isotropic by an ISOR restraint. The O atoms are resolved into two positions and give the site occupany of the major component.

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.
