Ammonium 2-amino-pyrazine-3-carboxyl-ate.

ABSTRACT: The title compound NH(4) (+)·C(5)H(4)N(3)O(2) (-) crystallizes with two formula units in the asymmetric unit. In each anion, the carboxyl-ate is deprotonated and the planar amino group [angle sums of 359 (3) and 355 (3)° at N] remains protonated. In the crystal, the cations and anions are bridged by N-H⋯O and N-H⋯N hydrogen bonds, forming a three-dimensional network.

Ammonium tris-(3-amino-pyrazine-2-carboxyl-ato-?N,O)nickelate(II) trihydrate.

Project description:The Ni(II) atom in the title hydrated salt, (NH(4))[Ni(C(5)H(4)N(3)O(2))(3)]·3H(2)O, is N,O-chelated by the three 3-aminopyrazine-2-carboxyl-ate ligands, resulting in a distorted octa-hedral mer-NiN(3)O(3) geometry for the metal.

Acridinium 3-carb-oxy-pyrazine-2-carboxyl-ate.

Project description: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 [dihedral angle = 1.21(2)°] acridine systems. The shortest distance between the centroids of the six-membered rings within the cations is 3.6315 (8) Å. In addition, C-H⋯π edge-to-face inter-actions are present.

Project description:The asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-anti-prismatic geometry. The polymeric chains that run along the a axis inter-act with the lattice water mol-ecules, generating a three-dimensional hydrogen-bonded network. The formate ion is disordered over two positions with respect to the non-coordinated atoms in a 1:1 ratio.

Poly[[hepta-μ(2)-aqua-bis-(μ(2)-pyrazine-2-carboxyl-ato)dibarium] bis-(pyrazine-2-carboxyl-ate)].

Project description:In the layered title coordination polymer, {[Ba(2)(C(5)H(3)N(2)O(2))(2)(H(2)O)(7)](C(5)H(3)N(2)O(2))(2)}(n), the coordination geometries around the two independent Ba(II) ions can be described as bicapped square-anti-prismatic [BaNO(9)] arrangements. A two-dimensional polymeric framework with (6,3) topology can be observed in the ac plane, the nodes being provided by Ba(II) ions and the connectors being N and O atoms belonging to pyrazine-2-carboxyl-ate ligands and O atoms of bridging water mol-ecules. Non-coordinating pyrazine-2-carboxyl-ate ions are located between the polymeric layers in the crystal and are interconnected through extensive O-H⋯N,O hydrogen bonding.

Hexa-kis-(propyl-ammonium) benzene-1,2,4,5-tetra-carboxyl-ate 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate tetra-hydrate.

Project description:The title organic salt, 6C(3)H(10)N(+)·C(10)H(2)O(8) (4-)·C(10)H(4)O(8) (2-)·4H(2)O, contains seven independent entities in the asymmetric unit which comprises three propyl-ammonium cations, two water mol-ecules, half a 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate dianion (H(2)btc(2-)) and half a benzene-1,2,4,5-tetra-carboxyl-ate tetra-anion (btc(4-)), the latter two anions being located about centres of inversion. One of the water mol-ecules is disordered over two positions in a 0.55 (2):0.45 (2) ratio. The combination of mol-ecular ions and water mol-ecules results in an extensive and complex three-dimensional network of hydrogen bonds, the network being made up of nine unique N-H⋯O inter-actions between the ammonium cations and the anions, as well as four unique O-H⋯O inter-actions between the water mol-ecules and the anions.

rac-Ammonium cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate.

Project description:In the structure of the title compound, NH(4) (+)·C(8)H(11)O(4) (-), the carboxyl and carboxyl-ate groups of the cation adopt C-C-C-O torsion angles of 174.9?(2) and -145.4?(2)°, respectively, with the alicyclic ring. The ammonium H atoms of the cations give a total of five hydrogen-bonding associations with carboxyl-ate O-atom acceptors of the anion which, together with a carboxyl O-H?O(carboxyl-ate) inter-action give sheet structures which lie in the (101) planes.
