Disordered structure of propane-1,2-diaminium dichloride
In the title compound, C(3)H(12)N(2) (2+)·2Cl(-), the cations are disordered over two well resolved positions in a 0.525 (13):0.475 (13) ratio. The disorder involves two C atoms which assume positions that make an almost mirror-sym-metrical system. Similar disorder is observed both at room temperature and at 120 (1) K. The conformation of the NCCN chain in both components is close to trans (the...
متن کاملCrystal structure of bis(propane-1,3-diaminium) hexafluoridoaluminate diaquatetrafluoridoaluminate tetrahydrate
The title compound, (C3H12N2)2[AlF6][AlF4(H2O)2]·4H2O, was obtained by a solvothermal method in ethanol as solvent and with aluminium hydroxide, HF and 1,3-di-amino-propane as educts. The asymmetric unit contains a quarter each of two crystallographically independent propane-1,3-di-ammonium dicat-ions, [AlF6](3-) and [AlF4(H2O)2](-) anions and four water mol-ecules. The cations, anions and thre...
متن کامل2,5-Dibenzoylbenzene-1,4-diaminium dichloride
The asymmetric unit of the title compound, C(20)H(18)N(2)O(2) (2+)·2Cl(-), is composed of one-half of the 2,5-dibenzoyl-benzene-1,4-diaminium dication, located on a centre of inversion, and one Cl(-) ion. The dihedral angle between the central benzene ring and the benzoyl phenyl ring is 53.3 (2)°. In the crystal structure, ions are linked to form a two-dimensional network parallel to the (10) p...
متن کاملPropane-1,2-diaminium bis(4-methoxybenzoate)
The asymmetric unit of the title salt, C(3)H(12)N(2) (2+)·2C(8)H(7)O(3) (-), contains two 4-meth-oxy-benzoate anions and one propane-1,2-diaminium cation. All the amino H atoms of the cation are involved in N-H⋯O hydrogen bonds with the carboxyl-ate O atoms of the anions.
متن کاملCrystal structure of N 1-benzyl-N 1,N 2,N 2-trimethylethane-1,2-diaminium dichloride
In the title mol-ecular salt, C12H22N2 (2+)·2Cl(-), which was obtained as a by-product in the attempted synthesis of a mercury derivative, the conformation of the N-C-C-N bond in the cation is anti [torsion angle = 175.1 (10)°]. In the crystal, the cations are linked to the anions by N-H⋯Cl hydrogen bonds, generating ion-triplets. These are linked by numerous weak C-H⋯Cl inter-actions, generati...
