Anhydrous pentaguanidinium dihydrogen nonavanado(IV)platinate(IV)
The title compound, (CH(6)N(3))(5)[H(2)PtV(9)O(28)], containing the nona-vanadoplatinate(IV) polyanion, was obtained by hydro-thermal reaction. The polyanion has approximate C(2v) symmetry. The two Pt-bound μ(2)-O atoms are protonated in the polyanion. The heteropolyanions form inversion-generated dimers, {[H(2)PtV(9)O(28)](2)}(10-), held together by each of the two μ(2)-O-H⋯μ(2)-O and μ(2)-O-H...

متن کامل2-Phenylanilinium dihydrogen phosphate
In the crystal structure of the title compound, C(12)H(12)N(+)·H(2)PO(4) (-), the dihydrogen phosphate anions and the 2-phenyl-anilinium cations are associated via O-H⋯O and N-H⋯O hydrogen bonds so as to build inorganic layers around the x = 1/2 plane. The organic entities are anchored between these layers through C-H⋯O hydrogen bonds, forming a three-dimensional infinite network. The dihedral ...
متن کامل2-Cyanoanilinium dihydrogen phosphate
In the cation of the title compound, C(7)H(7)N(2) (+)·H(2)PO(4) (-), the nitrile group and the benzene ring are almost coplanar (r.m.s. deviation = 0.0035 Å). The cations and anions are connected by inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, together with π-π inter-actions [centroid-centroid distance = 3.8131 (9) Å], forming a three-dimensional network.
متن کاملOrphenadrinium dihydrogen citrate
In the title salt, C(18)H(24)NO(+)·C(6)H(7)O(7) (-), the dihedral angle between the benzene rings in the cation is 74.2 (5)°. In the crystal, anion-anion O-H⋯O hydrogen bonds and weak O-H⋯O inter-actions form infinite chains along [100]. Between these chains, cation-anion N-H-O hydrogen bonds are observed, forming an alternate pattern of cation and anion layers and leading to a two-dimensional ...
