Acridinium 3-carboxypyrazine-2-carboxylate
The title ion pair, C(13)H(10)N(+)·C(6)H(3)N(2)O(4) (-), contains a protonated acridine cation and a 3-carb-oxy-pyrazine-2-carboxyl-ate monoanion, which are linked together through O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds. These hydrogen bonds generate a C(10) chain graph-set motif. The crystal structure is further stabilized by extensive π-π stacking inter-actions between nearly parallel [di...
متن کامل3-Hydroxypyridinium-2-carboxylate
Comparable to many amino acids, the title compound, C(6)H(5)NO(3), is a substitution product of picolinic acid. The mol-ecule shows approximate non-crystallographic C(s) symmetry. Like many amino acids, the mol-ecule is present in its zwitterionic state. Intra- as well as inter-molecular hydrogen bonds are observed, the latter connecting the mol-ecules into zigzag chains along the crystallograp...

In the mol-ecule of the title compound, C(11)H(12)ClN(3)O(3), the five membered ring adopts an envelope conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
متن کاملAcridinium 2-hydroxybenzoate
In the title compound, C(13)H(10)N(+)·C(7)H(5)O(3) (-) or (acrH)(+)(Hsal)(-), the asymmetric unit contains one acridinium cation and one salicylate anion. The acridinium N atom is protonated and the carb-oxy-lic acid group of salicylic acid is deprotonated. Both moieties are planar, with an r.m.s. deviation of 0.0127 Å for the acr cation and 0.0235 ° for the sal anion. They are aligned with a d...
متن کاملcatena-Poly[[(aqualithium)-μ-3-carboxypyrazine-2-carboxylato-κ4 O 2,N 1:O 3,N 4] monohydrate]
The polymeric structure of the title compound {[Li(C(6)H(3)N(2)O(4))(H(2)O)]·H(2)O}(n), contains two symmetry-independent Li(I) complex units, both having distorted trigonal-bipyramidal coordination environments. The Li(I) ions are bridged by both the N and O atoms of the ligands, generating two symmetry-independent polymeric chains propagating along the b-axis direction. In both ligands, the s...
