Bis(2-amino-3-carb-oxy-pyrazin-1-ium) sulfate dihydrate.

ABSTRACT: The crystal structure of the title compound, 2C(5)H(6)N(3)O(2) (+)·SO(4) (2-)·2H(2)O, displays a variety of N-H?O and O-H?O hydrogen bonds in which all potential donors and acceptors are involved. In the crystal, cations and anions are inter-connected, forming R(3) (3)(10) and R(2) (2)(8) ring motifs whereas the anions and water mol-ecules form R(2) (3)(10) rings, which develop in chains running along [100]. The resulting three-dimensional network exhibits undulating sheets parallel to (011), marked by the presence of R(6) (6)(26) rings in which six cations are involved.

Bis(5-amino-3-carb-oxy-1H-1,2,4-triazol-4-ium) sulfate dihydrate.

Project description:The crystal structure of the title compound, 2C(3)H(5)N(4)O(2) (+)·SO(4) (2-)·2H(2)O, displays a three-dimensional framework in which mixed infinite chains [oriented parallel to (510) and ([Formula: see text]10)] inter-fere, forming tunnels extending parallel to the c axis. Inter-molecular O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonds ensure the unity of the structure and generate centrosymmetric R(4) (4)(14) and R(4) (2)(8) rings. The S atom lies on a twofold axis.

Project description:In crystal structure of the title compound, C(5)H(6)N(3)O(2) (+)·NO(3) (-)·H(2)O, inter-molecular N-H?O, O-H?N and O-H?O hydrogen bonds link the cations, anions and water mol-ecules into ribbons extending in [10]. Weak inter-molecular C-H?O hydrogen bonds further link these ribbons into sheets parallel to (3).

2-Amino-3-carb-oxy-pyrazin-1-ium dihydrogen phosphate.

Project description:In the crystal structure of the title compound, C(5)H(6)N(3)O(2) (+)·H(2)PO(4) (-), the dihydrogen phosphate anions are linked through short O-H?O hydrogen bonds, forming infinite double chains running parallel to the b axis. Centrosymetric N-H?O hydrogen-bonded cationic dimers form bridges between these chains by means of inter-molecular N-H?O and O-H?O hydrogen bonds, leading to a two-dimensional network parallel to (100) in which R(3) (3)(12), R(4) (3)(10) R(2) (2)(8) and C(4) graph-set motifs are generated. Weak inter-molecular C-H?O hydrogen bonds connect these layers, forming a three-dimensional network.

2-Amino-3-carb-oxy-pyrazin-1-ium perchlorate bis-(2-amino-pyrazin-1-ium-3-carboxyl-ate) monohydrate.

Project description: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 by O-H?N and O-H?O hydrogen bonds involving perchlorate anions and water mol-ecules, forming a three-dimensional network. Intra-molecular N-H?O and weak inter-molecular C-H?O hydrogen bonds are also present.

Bis(2-amino-3-carb-oxy-pyridinium) sulfate trihydrate.

Project description:In the title compound, 2C(6)H(7)N(2)O(2) (+)·SO(4) (2-)·3H(2)O, there are two independent cations which are connected into N-H?O hydrogen-bonded dimers. In the crystal, O-H?O hydrogen-bonded sulfate-water sheets run parallel to (001) and are linked into a three-dimensional network via inter-molecular N-H?O and O-H?O hydrogen bonds through the 2-amino-nicotinium dimers. Further stabilization is provided by weak inter-molecular C-H?O hydrogen bonds. R(4) (3)(10) and R(2) (2)(8) graph-set rings are observed. The crystal studied was an inversion twin with refined components of 0.45?(6) and 0.55?(6).

Tetra-aqua-bis-(piperazin-1-ium)cobalt(II) bis-(sulfate) dihydrate.

Project description:In the centrosymmetric title compound, [Co(C4H11N2)2(H2O)4](SO4)2·2H2O, the Co(II) atom is coordinated in a distorted octa-hedral geometry by four water O atoms and two piperazinium N atoms. These four water O atoms define an equatorial plane with a maximum deviation of 0.0384 (1) Å while the two piperazinium N atoms complete the octa-hedron in the axial positions. Neighboring complex mol-ecules and sulfate anions are connected through an extensive network of N-H⋯O and O-H⋯O hydrogen bonds, which link the different chemical species into layers in the ab plane. Additional Owater-H⋯O hydrogen bonds involving the non-coordinating water mol-ecules and C-H⋯O inter-actions connect these layers into a three-dimensional supra-molecular structure.

Poly[[bis-(?-3-amino-5-carb-oxy-benzoato-?(2)N:O(1))diaqua-zinc] dihydrate].

Project description:The Zn(II) atom in the title polymeric compound, {[Zn(C(8)H(6)NO(4))(2)(H(2)O)(2)]·2H(2)O}(n), lies on a center of inversion and is coordinated by two amine N atoms and two carboxyl-ate O atoms from two 3-amino-5-carb-oxy-benzoate anions along with two water mol-ecules in a distorted octa-hedral geometry. The bridging nature of the anion generates a layer motif parallel to (100). Hydrogen bonds of the N-H?O and O-H?O types exist in the structure. One H atom of the coordinated water mol-ecule and one H atom of the solvent water mol-ecule are each disordered over two positions in a 1:1 ratio.

Project description:The title salt, C(14)H(16)N(4) (2+)·2C(14)H(9)O(4)S(2) (-)·2H(2)O, was obtained by the co-crystalization of 2,2'-dithio-dibenzoic acid with 1,4-bis-(imidazol-1-ylmeth-yl)benzene.

O-H?O, O-H?S and N-H?O hydrogen-bonding inter-actions among the components lead to the formation of a three-dimensional network.
