title: Pentaethylenehexaminemanganese(II) pentaborate.
abstract: The title compound, (pentaethylenehexamine-kappa(6)N)manganese(II) 4,4',6,6'-tetrahydroxy-2,2'-spirobi(cyclotriboroxane)(1-), [Mn(C(10)H(28)N(6))][B(5)O(6)(OH)(4)](2), was synthesized under mild solvothermal conditions. The B(5)O(6)(OH)(4)(-) units are connected to one another via hydrogen bonds, forming a three-dimensional framework with large channels along the a and c axes, in which the templating [Mn(C(10)H(28)N(6))](2+) cations are located. The Mn(II) complex cation has a twofold axis and the coordination geometry of the MnN(6) group is that of a distorted trigonal prism.
