title: trans-Dichlorido(1,4,8,11-tetra-azacyclo-tetra-deca-ne)manganese(III) tetra-fluorido-borate.
abstract: In the title manganese(III) complex, [MnCl(2)(C(10)H(24)N(4))]BF(4) or trans-[MnCl(2)(cyclam)]BF(4) (cyclam is the tetra-dentate amine ligand 1,4,8,11-tetra-azacyclo-tetra-deca-ne), the Mn(III) ions occupy the center of a distorted octa-hedron coordinated by all four ligand nitro-gen donors in the macrobicyclic cavity and two chloride ions occupy the axial positions. Intra-molecular hydrogen bonding involving the coordinated chloride ions and the hydrogen atoms of the cyclam ligand is observed. Inter-molecular hydrogen bonding involving the tetrafluoridoborate anion and hydrogen atoms of the cyclam ligand leads to an infinite one-dimensional chain along the a axis. The tetra-fluoridoborate and inorganic units are linked by N-H⋯F hydrogen bonds. The structure may be compared with those of analogous compounds [MnCl(2)(cyclam)]ClO(4) and [Mn(CN)(2)(cyclam)]ClO(4).
