title: Triaqua-(1,4,7-triaza-cyclo-nonane-κN,N,N)nickel(II) bromide nitrate.
abstract: In the title half-sandwich compound, [Ni(C(6)H(15)N(3))(H(2)O)(3)]Br(NO(3)), the central Ni(II) ion, lying on a threefold rotation axis, is six-coordinated by three amine N atoms from the face-capping triaza macrocycle and three water O atoms in a slightly distorted octa-hedral geometry. In the crystal, O-H⋯O hydrogen bonding and weak O-H⋯Br inter-actions associate the Ni(II) cations and the counter-ions into a three-dimensional supra-molecular network.
