1-Methylpiperazine-1,4-diium dipicrate
IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: 1-methyl-piperazine-1,4-diium bis-(2,4,6-trinitro-phen-ol-ate)], C(5)H(14)N(2) (2+)·2C(6)H(2)N(3)O(7) (-), the ionic components are connected by relatively strong N-H⋯O hydrogen bonds into centrosymmetric six-membered conglomerates, which comprise two dications and four anions. Besides Coulombic inter-actions, only weak C-H⋯O inte...
متن کاملBis(1-methylpiperazine-1,4-diium) tetrachloridocuprate(II)
The title compound, (C(5)H(14)N(2))[CuCl(4)], was synthesized by hydro-thermal reaction of CuCl(2) with 1-methyl-piperazine in an HCl/water solution. Both amine N atoms are protonated. The piperazine ring adopts a chair conformation. The Cu-Cl distances in the tetrahedral anion are in the range 2.2360 (7)-2.2732 (7) Å. In the crystal, moderately strong and weak inter-molecular N-H⋯Cl hydrogen b...
متن کامل1-(2-Azaniumylethyl)piperazine-1,4-diium trinitrate
In the title salt, C(6)H(18)N(3) (3+)·3NO(3) (-), the piperazine ring adopts a chair conformation and the ethyl-ammonium group is equatorial relative to the piperazine ring, and in an all-trans conformation. In the crystal, strong charge-assisted N-H⋯O hydrogen bonds link the piperazinediium trications and the nitrate anions into a three-dimensional network.
