Octane-1,8-diyldipyridinium dibromide dihydrate
The asymmetric unit of the title compound, C(18)H(26)N(2) (2+)·2Br(-)·2H(2)O, consists of one-half of the organic cation, one Br(-) anion and one water mol-ecule. The organic cation is situated on a centre of inversion. The dihedral angle between the pyridine ring and the plane of the central linkage is 59.3 (1)°. The cations, anions and water mol-ecules are linked via O-H⋯Br, C-H⋯Br and C-H⋯O ...
متن کامل2,2′-Ethylenediisoquinolinium dibromide dihydrate
In the title compound, C(20)H(18)N(2) (2+)·2Br(-)·2H(2)O, the complete dication is generated by a crystallographic centre of symmetry. In the crystal, O-H⋯Br, C-H⋯Br and C-H⋯O hydrogen bonds and π-π stacking [shortest centroid-centroid separation = 3.657 (2) Å] help to establish the packing.

The organic cation in the title compound, C(14)H(18)N(2) (2+)·2Br(-)·2H(2)O, is situated on an inversion centre. The cations, anions and water mol-ecules are linked via O-H⋯Br, C-H⋯Br and C-H⋯O hydrogen bonds, and π-π stacking inter-actions between adjacent pyridine rings, with a centroid-centroid separation of 3.8518 (17) Å.
متن کاملBromido(1,4,7,10,13-pentaazacyclohexadecane)cobalt(III) dibromide dihydrate
The title salt, [CoBr(C11H27N5)]Br2·2H2O, contains a complex cation with mirror symmetry and two Br(-) counter-anions that are likewise located on the mirror plane. The central Co(III) atom of the complex cation has one Br(-) ion in an axial position, one N atom of the penta-dentate macrocyclic ligand in the other axial position and four N atoms of the ligand in equatorial positions, defining a...
متن کامل1,4-Dimethylpiperazine-1,4-diium dibromide dihydrate
In the title hydrated mol-ecular salt, C(6)H(16)N(2) (2+)·2Br(-)·2H(2)O, the complete 1,4-dimethyl-piperazine-1,4-diium dication is generated by crystallographic inversion symmetry and both exocyclic C-N bonds are in equatorial orientations. In the crystal, the components are linked by N-H⋯O and O-H⋯Br hydrogen bonds, generating chains propagating in [110].
