Crystal structure of bis(3,5-dimethylpyridine-κN)bis(methanol-κO)bis(thiocyanato-κN)cobalt(II)

The asymmetric unit of the title complex, [Co(NCS)2(C7H9N)2(CH3OH)2], comprises of one CoII cation located on a centre of inversion, one thiocyanate ligand, one methanol ligand and one 3,5-dimethylpyridine ligand. The CoII cation is octahedrally coordinated by two terminal N-bonding thiocyanate anions, two methanol molecules and two 3,5-dimethylpyridine ligands into a discrete complex. The complex molecules are linked by intermolecular O—H...S hydrogen bonding into chains that elongate in the direction parallel to the b axis

Crystal structure of diaquabis(2-chloropyridine-κN)bis(thiocyanato-κN)nickel(II)

The asymmetric unit of the title compound, [Ni(NCS)2(C5H4ClN)2(H2O)2], consists of one nickel(II) cation that is located on a center of inversion and one thiocyanate anion, one water molecule and one 2-chloropyridine ligand all occupying general positions. The NiII cation is octahedrally coordinated by two terminal N-bound thiocyanato ligands, two aqua ligands and two N-bound 2-chloropyridine ligands into discrete complexes. Individual complexes are linked by intermolecular O—H...S and O—H...Cl hydrogen-bonding interactions into a layered network extending parallel to the bc plane. Weak interactions of types C—H...S and C—H...Cl consolidate the crystal packing

Redetermination of bis(acetylacetonato-κ2O,O′)(1,10-phenanthroline-κ2N,N′)manganese(II)

In the crystal structure of the title compound, [Mn(C5H7O2)2(C12H8N2)], the Mn2+ cation is coordinated by one bidentate 1,10-phenanthroline ligand and two acetylacetonate anions within a slightly distorted N2O4 octahedron. The asymmetric unit consists of one Mn2+ cation situated on a twofold rotation axis, one half of a 1,10-phenanthroline ligand and one acetylacetonate anion. In comparison with the previous determination based on visually estimated intensities recorded on precession photographs, the current redetermination with image-plate data reveals bond lengths and angles with much higher precision

Crystal structure of poly[[(2,2′-bipyridine)manganese(II)]-di-μ-thiocyanato]

In the crystal structure of the polymeric title compound, [Mn(NCS)2(C10H8N2)]n, the MnII cations are coordinated by one chelating 2,2′-bipyridine ligand and four thiocyanate anions (two N- and two S-coordinating), forming a distorted [MnN4S2] octahedron. The asymmetric unit consists of one manganese cation located on a twofold rotation axis and half of a 2,2′-bipyridine ligand, the other half being generated by the same twofold rotation axis, as well as one thiocyanate anion in a general position. The MnII cations are linked by two pairs of μ1,3-bridging thiocyanate ligands into chains along the c axis; because the N atoms of the 2,2′-bipyridine ligands, as well as the N and the S atoms of the thiocyanate anions, are each cis-coordinating, these chains show a zigzag arrangement

Bis(acetylacetonato-κ2O,O′)(pyridine-κN)(thiocyanato-κN)manganese(III): a redetermination using data from a single crystal

In the crystal structure of the title compound, [Mn(C5H7O2)2(NCS)(C5H5N)], the Mn3+ cation is coordinated by two acetylacetonate anions, one terminal thiocyanate anion and one pyridine ligand within a slightly distorted octahedron. The asymmetric unit consists of half a complex molecule with the Mn3+ cation, the thiocyanate anion and the pyridine ligand located on a mirror plane. The acetylacetonate anion is in a general position. The title compound was previously described [Stults et al. (1975). Inorg. Chem. 14, 722–730] but could only be obtained as a powder. Suitable crystals have now been obtained for a high-precision single-crystal structure determination

Crystal structure of bis(4-benzoylpyridine-κN)bis(methanol-κO)bis(thiocyanato-κN)cobalt(II)

The crystal structure of the title compound, [Co(NCS)2(C12H9NO)2(CH3OH)2], consists of cobalt(II) cations that are octahedrally coordinated by two N-terminal bonding thiocyanato anions, two methanol molecules and two 4-benzoylpyridine ligands into discrete complexes that are located on centres of inversion. These complexes are further linked by O—H...O hydrogen bonding between the hydroxy H atom of the methanol ligand and the carbonyl O atom of the 4-benzoylpyridine ligand of a neighboring complex into layers parallel to (101). No pronounced intermolecular interactions are observed between these layers

Crystal structure of tetraaquabis(thiocyanato-κN)nickel(II)–2,5-dimethylpyrazine (1/4)

In the crystal structure of the title compound, [Ni(NCS)2(H2O)4]·4C6H8N2, the NiII cations are coordinated by four water ligands and two trans-coordinated terminally N-bonded thiocyanate anions in a slightly distorted octahedral geometry. The asymmetric unit consists of a Ni2+ cation located on a centre of inversion, two water molecules and one thiocyanate ligand, as well as two uncoordinated 2,5-dimethylpyrazine ligands in general positions. In the crystal, discrete complex molecules are linked into a three-dimensional network by O—H...N hydrogen bonding between the water H atoms and the 2,5-dimethylpyrazine N atoms

Crystal structure of diaquabis(2,6-dimethylpyrazine-κN)bis(thiocyanato-κN)cobalt(II) 2,5-dimethylpyrazine trisolvate

In the crystal structure of the title compound, [Co(NCS)2(C6H8N2)2(H2O)2]·3C6H8N2, the CoII cation is coordinated by two terminally N-bound thiocyanate anions, two water molecules and two 2,6-dimethylpyrazine ligands, forming a discrete complex with a slightly distorted octahedral N4O2 coordination environment. The asymmetric unit contains one CoII cation and three halves of 2,5-dimethylpyrazine solvate molecules, all entities being completed by inversion symmetry, as well as one thiocyanate anion, an aqua ligand and a 2,6-dimethylpyrazine ligand, all in general positions. In the crystal, discrete complexes are arranged in a way that cavities are formed where the noncoordinating 2,5-dimethylpyrazine molecules are located. The coordination of the latter to the metal is prevented due to the bulky methyl groups in vicinal positions to the N atoms, leading to a preferential coordination through the 2,6-dimethylpyrazine ligands. The complex molecules are linked by O—H...N hydrogen bonds between the water H atoms and the N atoms of 2,5-dimethylpyrazine solvent molecules, leading to a layered structure extending parallel to (100)
