Quaternary tryptammonium salts: N,N-dimethyl-N-n-propyltryptammonium (DMPT) iodide and N-allyl-N,N-dimethyltryptammonium (DMALT) iodide

N,N′,N′′-Tricyclo­hexyl­guanidinium iodide

In the title compound, C(19)H(36)N(3) (+)·I(-), the orientation of the cyclo-hexyl rings around the planar (sum of N-C-N angles = 360°) CN(3) (+) unit produces steric hindrance around the N-H groups. As a consequence of this particular orientation of the tricyclo-hexyl-guanidinium cation (hereafter denoted CHGH(+)), hydrogen bonding is restricted to classical N-H⋯I and non-clasical (cyclo-hex-y...

4-Eth­oxy­carbonyl-N,N,N-trimethyl­anilinium iodide

In the title molecular salt, C(12)H(18)NO(2) (+)·I(-), the C atoms of the ethyl group are disordered over two sets of sites [occupancies of 0.76 (4) and 0.24 (4)]. In the crystal, ion pairs linked by weak C-H⋯I interactions occur.

QTAIM study of Bonding and Structure of Pure Atomic Clusters,Part III : Nn Clusters (n= 4,6)

DFT and QTAIM computations have been performed on numbers of pure nitrogen cluster speciesi.e. Nn (n = 4, 6) for investigating the structure and bonding. This study is critical since thesemolecules have been nominated as the good synthetic targets of High Energy Materials (HEM).0nthe other hand the decomposition mechanism is closely depends on the bonding pattern. Thislatter concept was searche...

Diaqua­iodido(2,3,5,6-tetra-2-pyridyl­pyrazine-κ3 N 2,N 1,N 6)manganese(II) iodide monohydrate

The asymmetric unit of the title compound, [MnI(C(24)H(16)N(6))(H(2)O)(2)]I·H(2)O, consists of a cationic Mn(II) complex, an I(-) anion and a solvent water mol-ecule. In the complex, the Mn(II) ion is six-coordinated in a considerably distorted octa-hedral environment defined by three N atoms of the tridentate 2,3,5,6-tetra-2-pyridyl-pyrazine (tppz) ligand, one I(-) anion and two O atoms of two...
