N,N'-Bis(2-aza-niumylbenz-yl)ethane-1,2-diaminium tetra-chloride.

ABSTRACT: The title compound, C(16)H(26)N(4) (4+)·4Cl(-), is based on a fully protonated tetra-amine. In the cation, both benzene rings are connected by an all-trans chain, and the rings are almost parallel, with an angle between the mean planes of 8.34?(12)°. The benzene rings are arranged in such a way that the NH(3) (+) substituents are oriented cis with respect to the central chain. This arrangement is a consequence of multiple N-H?Cl hydrogen bonds, involving all N-H groups in the cation and the four independent Cl(-) anions. These contacts have strengths ranging from weak to strong (based on H?Cl separations), and generate a complex three-dimensional crystal structure with no preferential crystallographic orientation for the contacts.

Project description:In the two anions of the title salt, C(2)H(10)N(2) (2+)·2C(8)H(5)N(8) (-)·2H(2)O, the central aromatic rings make dihedral angles of 13.53?(6) and 6.53?(7)° with the deprotonated tetra-zole rings, and 11.39?(6) and 10.41?(9)° with the other tetra-zole groups.

N,N'-Bis(2-amino-benz-yl)ethane-1,2-diaminium dinitrate.

Project description:In the title salt, C16H24N4 (2+)·2NO3 (-), both the cation and anion are placed in general positions, although the cation displays non-crystallographic inversion symmetry, with the aliphatic chain extended in an all-trans conformation. The benzene rings are almost parallel, with a dihedral angle between their mean planes of 3.3?(6)°. The nitrate ions are placed in the vicinity of the protonated amine groups, forming efficient N-H?O inter-ion hydrogen bonds. Each nitrate ion in the asymmetric unit bridges two symmetry-related cations, forming an R 4 (4)(18) ring, a common motif in organic ammonium nitrate salts. This results in the formation of chains along [010] with alternating cations and anions. The neutral amine groups are involved in slightly weaker N-H?O hydrogen bonds with the nitrate O atoms, and there are also a number of C-H?O hydrogen bonds present. The resulting supra-molecular structure is based on a two-dimensional network extending in the ab plane.

Project description:In the title compound, C(2)H(10)N(2) (2+)·2C(9)H(3)Br(4)O(4) (-)·CH(4)O, the N atoms of the ethane-1,2-diamine mol-ecule are protonated.

In addition, the crystal structure exhibits a C-Br?O halogen bond [3.20?(3)?Å] and a Br?Br inter-action [3.560?(2)?Å].

Crystal structure of N,N'-[(ethane-1,2-di-yl)bis-(aza-nediylcarbono-thio-yl)]bis-(benzamide).

Project description:The reaction of benzoyl chloride and ethyl-endi-amine in the presence of potassium thio-cyanate yielded a white solid, C18H18N4O2S2, which consists of two benzoyl-thio-ureido moieties connected by an ethyl-ene chain.

Ethane-1,2-diaminium dipicrate dihydrate.

Project description:The title compound, C(2)H(10)N(2) (2+)·2C(6)H(2)N(3)O(7) (-)·2H(2)O, crystallizes with a complete picrate anion and half an ethyl-enediammonium dication on a mirror plane, and two half-water mol-ecules (both on a mirror plane) in the asymmetric unit. The N atoms from separate half ethyl-enediammonium dications are in near proximity to a phenolate O atom and two o-NO(2) groups from the picrate anion, which, along with the water mol-ecule form N-H?O, O-H?O and weak intermolecular C-H?O hydrogen bonds that create cyclic patterns with graph-set descriptors R(2) (4)(8), R(4) (4)(12), and R(4) (4)(16). The crystal packing is strongly influenced by these inter-molecular inter-actions between symmetry-related water mol-ecules, the half ethyl-enediammonium dication and the picrate anion, forming a three-dimensional supermolecular structure.
