Ethylenediaminium hemioxalate thiocyanate
In the title compound, C(2)H(10)N(2) (2+)·0.5(C(2)O(4))(2-)·NCS(-), the ethyl-enediaminium dication adopts a (+)-synclinal conformation with an N-C-C-N torsion angle of 62.64 (15)°. The oxalate dianion lies across an inversion centre. In the crystal structure, the ions are linked through N-H⋯N, N-H⋯O and C-H⋯S hydrogen bonds, leading to the formation of a three-dimensional network.
متن کاملEthylenediaminium niobium oxyfluoride.
The title compound, bis(ethylenediaminium) mu-oxo-bis[tetrafluorooxoniobium(V)], (C2H10N2)2[Nb2O3F8], is a novel organically templated niobium oxyfluoride. It consists of isolated [Nb2O3F8]4- octahedral dimers charge balanced by ethylenediaminium cations, two of which lie about inversion centres. Two NbO2F4 octahedra are fused through a common O atom to form the dimers. Characteristic short ter...
متن کامل3-Carboxyanilinium hemioxalate
In the title compound, C(7)H(8)NO(2) (+)·0.5C(2)O(4) (2-), the asymmetric unit consists of an 3-carboxy-anilinium cation, and one-half of an oxalate anion, which lies on a twofold rotation axis. The crystal packing is consolidated by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. The structure is built from infinite chains of cations and oxalate anions extending parallel to the b and c axes. T...
متن کامل2-Ethyl-1H-imidazol-3-ium hemioxalate oxalic acid monohydrate
In the title compound, C(5)H(9)N(2) (+)·0.5C(2)O(4) (2-)·C(2)H(2)O(4)·H(2)O, the anions, cations and water mol-eculars are linked by N-H⋯O and O-H⋯O hydrogen bonds which define a tightly bound three-dimensional structure. The title compound is a layered structure as viewed along the a or c axis; one layer contains water and oxalic acid mol-ecules, the other the imidazolium cation. The C atoms o...
متن کاملN-[2-(2-Chlorophenyl)-2-hydroxyethyl]propan-2-aminium hemioxalate
The asymmetric unit of the title compound, C(11)H(17)ClNO(+)·0.5C(2)O(4) (2-), consists of one N-[2-(2-chloro-phen-yl)-2-hydroxy-ethyl]propan-2-ammonium cation and one-half of a centrosymmetric oxalate anion. In the cation, the C/C/N plane of the ethyl-ammonium group is almost perpendicular to the benzene ring, with a dihedral angle of 88.72 (17)°. In the crystal structure, the two components a...
