Bis{bis-(azido-?N)bis-[bis-(pyridin-2-yl-?N)amine]cobalt(III)} sulfate dihydrate.

ABSTRACT: The search for new mol-ecular materials with inter-esting magnetic properties, using the pseudohalide azide ion and di-2-pyridyl-amine (dpa, C10H9N3) as a chelating ligand, led to the synthesis and structure determination of the title compound, [Co(N3)2(dpa)2]2SO4·2H2O. The crystal structure comprises discrete [Co(dpa)2(N3)2](+) cations, sulfate anions, as well as H2O solvent mol-ecules. The Co(III) cations display a slightly distorted octa-hedral coordination sphere defined by two N atoms from azide anions and four N atoms from the pyridyl rings of two dpa ligands. In the crystal, extensive C-H?O, N-H?O, and O-H?O inter-actions result in supra-molecular sheets that lie parallel to the ab plane. The sheets are further linked through O-H?N inter-actions between the water mol-ecules of one sheet and azide anions of another sheet, forming a supra-molecular framework.

Hexaaqua-cobalt(II) bis-[4-(pyridin-2-yl-meth-oxy)benzoate] dihydrate.

Project description:The Co(II) atom in the title salt, [Co(H(2)O)(6)](C(13)H(10)NO(3))(2)·2H(2)O, lies on a center of inversion in an octa-hedron of water mol-ecules. The cations, anions and uncoordinated water mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen bonds into a three-dimensional network.

Poly[[bis-[?2-1,2-bis-(pyridin-4-yl)ethene-?(2) N:N']bis-(thio-cyanato-?N)cobalt(II)] 1,2-bis-(pyridin-4-yl)ethene monosolvate dihydrate].

Project description:The asymmetric unit of the title compound, {[Co(NCS)2(C12H10N2)2]·C12H10N2·2H2O} n , consists of two independent Co(II) cations, four distinct thio-cyanate anions, six 1,2-bis-(pyridin-4-yl)ethene (4-bpe) mol-ecules and four lattice water mol-ecules. The Co(II) cations are each coordinated by two N-bonded thio-cyanate anions and four 4-bpe ligands within a slightly distorted CoN6 octa-hedron. The two independent Co(II) cations are linked by the 4-bpe ligands into two distinct layers, parallel to the ac and bc planes, that inter-penetrate. From this arrangement, channels are formed in which non-coordinated 4-bpe and lattice water mol-ecules are hydrogen-bonded into chains that elongate in the c-axis direction.

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.

The crystal packing is stabilized by inter-molecular C-H?F and C-H?O hydrogen bonds.

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 (?d ? 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).

Project description:The asymmetric unit of the title compound, [Co(C(9)H(7)O(4))(2)(C(12)H(10)N(2))(2)(H(2)O)(2)], consists of one Co(2+) ion, one mono-deprotonated 2-(4-carboxyl-atophen-yl)acetate carboxylic acid, one 1,2-bis-(pyridin-4-yl)ethane mol-ecule and one water mol-ecule. The Co(II) atom is situated on a crystallographic center of inversion and is octa-hedrally coordinated by two O atoms from two anions, two N atoms of two 1,2-bis-(pyridin-4-yl)ethane mol-ecules and two O atoms from two water mol-ecules. A three-dimensional network is established by inter-molecular O-H?O and O-H?N hydrogen bonds.

trans-Bis[2-(piperazin-1-yl)-ethan-amine]-bis-(saccharinato)cobalt(II).

Project description:In the centrosymmetric title complex, [Co(C(7)H(4)NO(3)S)(2)(C(6)H(15)N(3))(2)], the Co(II) ion is coordinated by two saccharinate (sac) anions and two neutral 2-piperazin-1-ylethanamine (ppzea) ligands, showing a distorted octa-hedral coordination. Sac is O-bonded via the carbonyl group, while ppzea acts as an N,N'-bidentate chelating ligand. The mol-ecules are connected by N-H⋯N and N-H⋯O hydrogen bonds, forming a linear chain running parallel to the crystallographic a axis. The compound is isostructural with the reported Ni, Zn, and Cd analogues.
