N,N′-Bis[2-(methoxycarbonyl)ethyl]ethane-1,2-diammonium dichloride
In the crystal structure of the title compound, C(10)H(22)N(2)O(4) (2+)·2Cl(-) or (H(2)Me(2)eddp)Cl(2) (H(2)Me(2)eddp(2+) is the dimethyl N,N'-di-3-propane-carboxylato-ethane-1,2-diyldiimin-ium cation), the packing is stabilized by an infinite two-dimensional ⋯Cl⋯H-N-H⋯Cl⋯ hydrogen-bonding network. In addition, short C-H⋯Cl contacts are observed.
متن کاملN,N′-Dicyclohexylethylenediammonium dichloride
In the title compound, C(14)H(30)N(2) (2+)·2Cl(-), the N,N'-dicyclo-hexyl-ethyl-enediammonium cation posseses crystallographic symmetry, and thus the compound crystallizes with two formula units per unit cell. In the crystal, the cations and anions are linked by N-H⋯Cl hydrogen bonds, giving a two-dimensional network with {6,3} topology.
متن کامل(m-Phenylenedimethylene)diammonium dichloride
The asymmetric unit of the title compound, C(8)H(14)N(2) (2+)·2Cl(-), contains one and a half of the dications and three chloride anions. The half molecule is completed by crystallographic twofold symmetry with two C atoms lying on the rotation axis. The two ammonium groups in each cation adopt a trans conformation with respect ot the benzene ring. The ammonium groups and chloride anions are in...

1.1 Définitions élémentaires Définition 1. Soit P ∈ k[X ] et a ∈ k. On dit que a est une racine de P si P (a) = 0, ou de manière équivalente si X − a divise P . On appelle multiplicité de a le plus grand entier μ tel que (X − a) divise P . Proposition 1. Si P ∈ k[X ] admet a1, . . . , al pour racines, de multiplicités respectives μ1, . . . , μl, alors il existe Q ∈ k[X ] tel que P = Q∏(X − ai)i...
متن کاملRedetermination of trans-cyclohexane-1,4-diammonium dichloride
A redetermination of the crystal structure of the title compound, C(6)H(16)N(2) (2+)·2Cl(-), was undertaken. All atomic coordinates including those of the H atoms were refined freely. The cation is located on a centre of symmetry. Important for the crystal structure are wavy hydrogen-bonded layers that are formed by ammonium groups and chloride anions, giving hydrogen-bonded rings.
