5,6-Dioxo-1,10-phenanthrolin-1-ium nitrate.

ABSTRACT: In the title salt, C(12)H(7)N(2)O(2) (+)·NO(3) (-), the monoprotonated cation is connected to the nitrate anion by a hydrogen bond. Weak C-H⋯O hydrogen bonds hold the planar cations together in a layer structure.

3,4,7,8-Tetra-methyl-1,10-phenanthrolin-1-ium nitrate monohydrate.

Project description:In the crystal of the title compound, C(16)H(17)N(2) (+)·NO(3) (-)·H(2)O, the tetra-methyl-1,10-phenanthrolinium cations, nitrate anions and lattice water mol-ecules are all located on a mirror plane with the methyl H atoms of the cation equally disordered over two sites about the mirror plane. The cation, anion and water mol-ecule are linked by O-H⋯O and N-H⋯O hydrogen bonds into a sheet parallel to the bc plane. π-π stacking between phenanthroline ring systems is observed in the crystal structure, the centroid-centroid distance being 3.4745 (6) Å.

1,10-Phenanthrolin-1-ium hydrogen d,l-tartrate dihydrate.

Project description:In the title hydrated molecular salt, C(12)H(9)N(2) (+)·C(4)H(5)O(6) (-)·2H(2)O, the cation is almost planar (r.m.s. deviation = 0.014 Å); the carbon skeleton of the anion assumes a trans conformation [C-C-C-C torsion angle = -179.86 (14)°]. The carboxyl end of one hydrogen tartrate anion forms a short hydrogen bond to the carboxyl-ate end of another anion [O⋯O = 2.508 (2) Å] in a head-to-tail manner, forming a chain; the chains and water mol-ecules inter-act, generating an O-H⋯O hydrogen-bonded layer. The cation binds to the layer by an N-H⋯O hydrogen bond.

Bis(1,10-phenanthrolin-1-ium) hexa-bromidoplatinate(IV) dihydrate.

Project description:The asymmetric unit of the title compound, (C(12)H(9)N(2))(2)[PtBr(6)]·2H(2)O, contains a protonated 1,10-phenanthroline cation (H-phen), one half of a [PtBr(6)](2-) anionic complex and a solvent water mol-ecule.
