In the title compound, C(19)H(26)N(2) (2+)·2Cl(-), the piperazinediium ring exhibits a chair conformation. The dihedral angle between the two benzene ring planes is 76.45 (13)°. Both amine-group H atoms participate in hydrogen bonding with the two Cl atoms.
The title compound, (C(5)H(14)N(2))[CuBr(4)], was synthesized by hydro-thermal reaction of CuBr(2) with 1-methyl-piperazine in an HBr/water solution. Both amine N atoms are protonated. The Cu-Br distances in the tetrahedral anion are in the range 2.3809 (11)-2.4131 (11) Å. In the crystal, moderately strong and weak inter-molecular N-H⋯Br hydrogen bonds link the anion and cation units into an in...
In the title compound, {(C(5)H(14)N(2))[Cd(2)Cl(6)]·H(2)O}(n), the asymmetric unit contains one piperazinediium cation, one [Cd(2)Cl(6)](2-) anion and a water mol-ecule. The coordination geometries of the two Cd(2+) cations are distorted octa-hedral. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride bridges, generating polymeric chains parallel to [010]. Neighbouring chai...
We report herein the solvent and temperature effects on the emission of the intermolecular exciplexes 1-cyanonaphthalene/triethylamine and 1-methylnaphthalene/triethylamine and the intramolecular exciplexes formed by the bichromophoric compounds diethyl-(3-naphthalen-1-yl-propyl)-amine (I), diethyl-(2-naphthalen-1-yl-ethyl)-amine (II), 3-[ethyl-(2-naphthalen-1-yl-ethyl)-amino]-propionitrile (II...
In the title salt, C10H10N2(2+)·2C7H4NS2(-), the complete 4,4'-bipyridine-1,1'-diium dication is generated by a center of symmetry. In the crystal, N-H⋯N hydrogen bonds are observed between the cations and anions.
In the title hydrated mol-ecular salt, C(6)H(16)N(2) (2+)·2Br(-)·2H(2)O, the complete 1,4-dimethyl-piperazine-1,4-diium dication is generated by crystallographic inversion symmetry and both exocyclic C-N bonds are in equatorial orientations. In the crystal, the components are linked by N-H⋯O and O-H⋯Br hydrogen bonds, generating chains propagating in [110].
