Bis(2-amino-4-methyl-pyrimidin-1-ium) hexa-aqua-cobalt(II) disulfate dihydrate.

ABSTRACT: In the title hydrated mixed-cation salt, (C(5)H(8)N(3))(2)[Co(H(2)O)(6)](SO(4))(2)·2H(2)O, the complete octa-hedral hexa-aqua complex cation is generated by crystallographic inversion symmetry. In the crystal, the components are linked by O-H?O and N-H?O hydrogen bonds, the latter, involving pyrimidinium cations and sulfate anions, generating R(2) (2)(8) loops. These, together with ?-? inter-actions between centrosymmetrically related pyrimidinium cations [centroid-centroid separation = 3.5460?(8)?Å], lead to the formation of a three-dimensional network.

Bis(2,6-diamino-pyridin-1-ium) hexa-aqua-cobalt(II) disulfate dihydrate.

Project description:In the title compound, (C(5)H(8)N(3))(2)[Co(H(2)O)(6)](SO(4))(2)·2H(2)O, the complete complex cation is generated by crystallographic inversion symmetry, such that the Co(II) cation is octa-hedrally coordinated by six water mol-ecules. The organic cation is essentially planar, with a maximum deviation of 0.013?(1)?Å. In the crystal structure, the ions and mol-ecules are linked into a pseudo-layered three-dimensional supra-molecular network via O-H?O and N-H?O hydrogen bonds. Weak inter-molecular ?-? inter-actions further stabilize the crystal structure [centroid-centroid distance = 3.5231?(4)?Å].

Crystal structure of bis-(di-methyl-ammonium) hexa-aqua-cobalt(II) bis-(sulfate) dihydrate.

Project description:The title salt, (C2H8N)2[Co(H2O)6)](SO4)2·2H2O, is isotypic with (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O. The Co-O bond lengths in the [Co(H2O)6](2+) complex cation show very similar distances as in the related Tutton salt (NH4)2[Co(H2O)6)](SO4)2 [average 2.093 (17) Å], but are significantly longer than in the isotypic Ni(II) compound (Δd ≃ 0.04 Å). The cobalt cation reaches an overall bond-valence sum of 1.97 valence units. The S-O distances are nearly equal, ranging from 1.454 (4) to 1.470 (3) Å [mean 1.465 (12) Å]; however, the O-S-O angles vary clearly from 108.1 (2) to 110.2 (2)° [average bond angle 109.5 (9)°]. The non-coordinating water mol-ecules and di-methyl-ammonium cations connect the sulfate tetrahedra and the [Co(H2O)6](2+) octa-hedron via O-H⋯O and N-H⋯O hydrogen bonds of weak up to medium strength into a three-dimensional framework whereby the complex metal cations and sulfate anions are arranged in sheets parallel to (001).

Hexaaqua-cobalt(II) tetra-aqua-bis(2-amino-pyrazine-?N)cobalt(II) disulfate dihydrate.

Project description:The reaction of cobalt(II) sulfate and 2-amino-pyrazine affords the title salt, [Co(H(2)O)(6)][Co(C(4)H(5)N(3))(2)(H(2)O)(4)](SO(4))(2)·2H(2)O. The metal atoms in the tetra-aqua-coordinated and hexa-aqua-coordinated complex cations lie on centers of inversion in slightly distorted octa-hedral geometries. The cations, anions and solvent water mol-ecules are linked by O-H?O, O-H?N and N-H?O hydrogen bonds into a three-dimensional network.

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.

Bis[2-(pyrimidin-2-ylamino)pyrimidin-ium] hexa-molybdate.

Project description:The title compound, (C(8)H(8)N(5))(2)[Mo(6)O(19)], was prepared by reaction of Mo(CO)(6) and dipyrimidylamine in refluxing toluene. The hexa-nuclear polyoxomolybdate anions lie on centres of inversion. Each 2-(pyrimidin-2-ylamino)pyrimidinium cation forms an intra-molecular N-H⋯N hydrogen bond and the cations are linked through self-complementary pairs of N-H⋯N hydrogen bonds into dimers across centres of inversion. The cations and anions are inter-linked through C-H⋯O contacts.

Bis(2-amino-4-methyl-pyrimidin-3-ium) trans-diaqua-bis-(pyrazine-2,3-di-car-boxylato)cobaltate(II) hexa-hydrate.

Project description:In the crystal structure of the mononuclear title compound, (C(5)H(8)N(3))(2)[Co(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·6H(2)O or (ampymH)(2)[Co(pyzdc)(2)(H(2)O)(2)]·6H(2)O (ampym = 2-amino-4-methyl pyrimidine, pyzdcH(2) = pyrazine-2,3-dicarb-oxy-lic acid), the Co(II) ion is hexa-coordinated by two (pyzdc)(2-) groups in the equatorial plane and two water mol-ecules in axial positions, giving an N(2)CoO(4) bound set. The (pyzdc)(2-) anion acts as a bidentate ligand through one carboxyl-ate group O atom and pyrazine ring N atom. There are diverse N-H⋯ O and O-H⋯O and O-H⋯N hydrogen-bonding inter-actions, which lead to the formation of a three-dimensional supra-molecular architecture. Off-set or slipped π-π stacking inter-actions are also observed between adjacent pyrimidine rings with face-to-face distances of 3.6337 (9) Å.

Bis(7-amino-1,2,4-triazolo[1,5-a]pyrimidin-4-ium) bis-(oxalato-κO,O)cuprate(II) dihydrate.

Project description:The structure of the title ionic compound, (C(5)H(6)N(5))(2)[Cu(C(2)O(4))(2)]·2H(2)O, consists of a centrosymmetric copper(II) oxalate dianion, two monoprotonated mol-ecules of the adenine analog 7-amino-1,2,4-triazolo[1,5-a]pyrimidine (7atp) and two water mol-ecules of crystallization. The Cu(II) ion, located on an inversion center, exhibits a sligthly distorted square-planar coordination geometry, in which two oxalate anions bind in a bidentate fashion. The triazolopyrimidine ligand is protonated at the N atom in position 4, instead of its most basic N atom in position 3. This fact may be explained by the network stability, which is provided through the formation of a two-dimensional wave-like network parallel to (50[Formula: see text]) by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds. These nets are further connected via C-H⋯O inter-actions.

Crystal structure of tetra-aqua-bis(3,5-di-amino-4H-1,2,4-triazol-1-ium)cobalt(II) bis-[bis-(pyridine-2,6-di-carboxyl-ato)cobaltate(II)] dihydrate.

Project description:The asymmetric unit of the title compound, [Co(C2H6N5)2(H2O)4][Co(C7H3NO4)2]2·2H2O, features 1.5 Co(II) ions (one anionic complex and one half cationic complex) and one water mol-ecule. In the cationic complex, the Co(II) atom is located on an inversion centre and is coordinated by two triazolium cations and four water mol-ecules, adopting an octa-hedral geometry where the N atoms of the two triazolium cations occupy the axial positions and the O atoms of the four water mol-ecules the equatorial positions. The two triazole ligands are parallel offset (with a distance of 1.38 Å between their planes). In the anionic complex, the Co(II) ion is six-coordinated by two N and four O atoms of the two pyridine-2,6-di-carboxyl-ate anions, exhibiting a slightly distorted octa-hedral coordination geometry in which the mean plane of the two pyridine-2,6-di-carboxyl-ate anions are almost perpendicular to each other, making a dihedral angle of 85.87 (2)°. In the crystal, mol-ecules are linked into a three-dimensional network via C-H⋯O, C-H⋯N, O-H⋯O and N-H⋯O hydrogen bonds.
