Synthesis and Structural Characterization of N,N′- Dipropyl-N,N,N′,N′-tetramethyl-1,2- ethylenediammonium Dichloride and Dibromide
N,N′ -Dipropyl-N,N,N′ ,N′-tetramethyl-1,2-ethylenediammonium dichloride (1) and dibromide (2) were prepared by the reaction of N,N,N′,N′-tetramethyl-1,2-ethylenediamine and the corresponding 1-halopropane. The structures of the compounds were characterized by single-crystal X-ray diffraction. 1 · 2H2O crystallizes in the triclinic crystal system, space group P1, with Z = 1, and 2 in the monocli...
متن کاملBiguanidinium dichloride
The asymmetric unit of the title compound, C(2)H(9)N(5) (2+)·2Cl(-), is composed of one diprotonated biguanidinium cation and two chloride anions. The diprotonated cation consists of two planar halves twisted by 36.42 (6)°. The ions are associated in the crystal structure by extensive hydrogen bonding into a three-dimensional network; the diprotonated biguanidinium cation is hydrogen bonded to ...
متن کاملEthylenediammonium dichloride
The title ionic compound, C(2)H(10)N(2) (2+)·2Cl(-), crystallizes with a center of symmetry within the cation. Each of the positively charged ammonium ends of the mol-ecule is trigonally hydrogen bonded to three different chloride counter-ions, while each of the chloride ions is trigonally hydrogen bonded to three different ethyl-enediammonium cations. The hydrogen-bonding network leads to stab...
متن کامل1,1′-Methylenedipyridinium dichloride monohydrate
In the crystal structure of the title salt, C(11)H(12)N(2) (2+)·2Cl(-)·H(2)O, the dication adopts a butterfly shape [dihedral angle between rings = 69.0 (1)°] with the water mol-ecule lying in the V-shaped cavity. Each O-H bond of the water molecule lies parallel to an aromatic ring and forms an O-H⋯Cl inter-action to a chloride anion. The methyl-ene C atom in the dication and the water O atoms...
متن کامل4-Ammoniobenzamidinium dichloride
The crystal structure of the title compound, C(7)H(11)N(3) (2+)·2Cl(-), has been determined as part of a project focusing on the ability of the benzamidine system to form strong hydrogen bonds in aqueous media. It is commonly used as a ligand in affinity chromatography for purification and immobilization of enzymes. A twofold rotation axis runs along the axis of the cation. The orientation of t...
