-N,N,N',N'-Tetrakis(2-pyridylmethyl)hexane-1,6-diamine]bis[dichloridomanganese(II)]The asymmetric unit of the title compound, [Mn2Cl4(C30H36N6)], contains one-half of the formula unit; a centre of inversion is located at the mid-point of the molecule. The two Mn2+ ions are bridged by the dual tridentate N,N,N',N'-tetrakis(2-pyridylmethyl)hexane-1,6-diamine ligand to form a dinuclear complex. Each Mn atom is five-coordinated in an approximately square-pyramidal geometry by three N atoms from the ligand and two Cl atoms. Intermolecular

interactions between adjacent pyridine rings with a centroid-centroid distance of 3.576 (2) Å are reported.
To a solution of N,N,N',N'-tetrakis(2-pyridylmethyl)hexane-1,6-diamine (0.50 g, 1.04 mmol) in EtOH (15 ml) was added MnCl2.4H2O (0.21 g, 1.06 mmol) and stirred for 1 h at room temparature. The volume of the solvent was reduced to 3 ml and ether (20 ml) was added. The so formed precipitate was separated by filtration and washed with EtOH/ether and dried under vacuum, to give a pale yellow powder (0.36 g). Crystals suitable for X-ray analysis were obtained from the slow evaporation of a MeOH solution. MS (FAB): m/z 570, 572 (Mn(tphn)Cl+).
H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.93 Å (aromatic) or 0.97 Å (CH2) and Uiso(H) = 1.2Ueq(C)].

The asymmetric unit of the title compound, [Mn2Cl4(C30H36N6)], contains one half of the formula unit; a centre of inversion is located in the midpoint of the compound (Figs. 1 and 2). In the complex, the two Mn2+ ions are bridged by the hexadentate ligand N,N,N',N'-tetrakis(2-pyridylmethyl)hexane-1,6-diamine (tphn) to form a centrosymmetric dinuclear complex. Mn atoms are five-coordinated in an approximately square pyramidal geometry by three N atoms from the tphn ligand and two Cl atoms. The Mn—N(amine) bond length (2.339 (2) Å) is slightly longer than the Mn—N(pyridyl) bond lengths (2.246 (3) and 2.232 (2) Å). The complex displays intermolecular π-π interactions between adjacent pyridine rings. The shortest distance between Cg1 (the centroid of six-membered ring N1—C5) and Cg1i (symmetry code i: 2 - x, 1 - y, 1 - z) is 3.576 (2) Å.
