[?-N,N'-Bis(2-pyridylmethyl-ene)ethane-1,2-diamine]bis-{aqua-[N,N'-bis-(2-pyridyl-methyl-ene)ethane-1,2-diamine]manganese(II)} tetra-kis(perchlorate).

ABSTRACT: The cation of the salt, [Mn(2)(C(14)H(14)N(4))(3)(H(2)O)(2)](ClO(4))(4), lies on a center of inversion, the center lying midway along the ethyl-ene chain of the bridging N,N'-bis-(2-pyridylmethyl-ene)ethane-1,2-diamine ligand. The Mn atom is chelated by two atoms N atoms of this bridging ligand, and is also coordinated by four N atoms of another ligand. The Mn atom is seven-coordinated in a penta-gonal-bipyramidal environment. The crystal structure displays inter-molecular ?-? inter-actions between adjacent pyridine rings, with a shortest centroid-centroid distance of 3.784?(3)?Å. The perchlorate is linked to the dinuclear cation by O-H?O hydrogen bonds.
