2-Amino-3-nitropyridinium perchlorate
The title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-), is comprised of discrete perchlorate anions and 2-amino-3-nitro-pyridinium cations. The anion has a typical tetra-hedral geometry while the cation presents a nearly planar [maximum deviation = 0.007 (8) Å] pyridinium ring. Undulating [C(5)H(6)N(3)O(2) (+)](n) chains extending along the c-axis direction are linked via N-H⋯O hydrogen bonds. The...
متن کامل2-Amino-3-carboxypyridinium perchlorate
The asymmetric unit includes two crystallographically independent equivalents of the title salt, C(6)H(7)N(2)O(2) (+)·ClO(4) (-). The cations and anions form separate layers alternating along the c axis, which are linked by N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds into a two-dimensional network parallel to (100). Further C-H⋯O contacts connect these layers, forming a three-dimensional network, in ...
متن کامل2-Amino-3-carboxypyrazin-1-ium perchlorate bis(2-aminopyrazin-1-ium-3-carboxylate) monohydrate
The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-)·2C(5)H(5)N(3)O(2)·H(2)O, comprises two symmetry-independent zwitterions, one cation, one perchlorate anion and one water mol-ecule. In the crystal, the three different types of organic entities are linked by N-H⋯O and N-H⋯N hydrogen bonds, forming undulating sheets parallel to (1-10). These sheets are in turn connected b...
متن کامل[(Z)-1-({3-[(3-Aminopropyl)(2-nitrobenzyl)amino]propyl}iminomethyl)naphthalen-2-olato]copper(II) perchlorate
In the title compound, [Cu(C(24)H(27)N(4)O(3))]ClO(4), the Cu(II) atom has a distorted square-planar coordination geometry and is surrounded by an N(3)O donor set composed of a secondary amine N, a primary amine H, an imino N and a naphthalen-2-olate O atom. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, mol-ecules are held together by inter-molecular N-H⋯O hydrogen bonds, leadi...
متن کامل2-(2-Hydroxy-3-methoxyphenyl)-1H-benzimidazol-3-ium perchlorate
In the title mol-ecular salt, C(14)H(13)N(2)O(2) (+)·ClO(4) (-), the ring systems in the cation are almost coplanar [dihedral angle = 5.53 (13)°]. Intra-molecular N-H⋯O and O-H⋯O hydrogen bonds generate S(6) and S(5) rings, respectively. In the crystal, the two H atoms involved in the intra-molecular hydrogen bonds also participate in inter-molecular links to acceptor O atoms of the perchlorate...
