Crystal structure of tetra-kis-(isonicotinamide-κN)bis-(thio-cyanato-κN)cobalt(II)-isonicotinamide-ethanol (1/2/1).

ABSTRACT: The asymmetric unit of the title compound, [Co(NCS)2(C6H6N2O)4]·2C6H6N2O·C2H5OH, comprises one Co(II) cation, two thio-cyanate anions, four coordinating and two solvent isonicotinamide molecules and one ethanol solvent mol-ecule. The Co(II) cations are octa-hedrally coordinated by four N-coordinating isonicotinamide ligands and two terminally N-bonded thio-cyanate anions. These discrete complexes are linked by inter-molecular N-H⋯O and N-H⋯S hydrogen-bonding inter-actions into a three-dimensional network. The two isonicotinamide and the ethanol solvent mol-ecules are embedded in channels of this network and are linked through further N-H⋯O and N-H⋯N hydrogen bonds to the network. The ethanol solvent mol-ecule is disordered over two sets of sites (occupancy ratio 0.6:0.4).

Crystal structure of bis-(isonicotinamide-κN (1))bis-(thio-cyanato-κN)zinc.

Project description:The asymmetric unit of the title complex, [Zn(SCN)2(C6H6N2O)2], consists of one Zn(2+) cation located on a twofold rotation axis, as well as of one thio-cyanate anion and one neutral isonicotinamide ligand, both occupying general positions. The Zn(2+) cation is tetra-hedrally coordinated into a discrete complex by the N atoms of two symmetry-related thio-cyanate anions and by the pyridine N atoms of two isonicotinamide ligands. The complexes are linked by inter-molecular C-H⋯O and N-H⋯O, and weak inter-molecular N-H⋯S hydrogen-bonding inter-actions into a three-dimensional network.

Pyridinium bis-(pyridine-κN)tetra-kis-(thio-cyanato-κN)ferrate(III).

Project description:In the title compound, (C5H6N)[Fe(NCS)4(C5H5N)2], the Fe(III) ion is coordinated by four thio-cyanate N atoms and two pyridine N atoms in a trans arrangement, forming an FeN6 polyhedron with a slightly distorted octa-hedral geometry. Charge balance is achieved by one pyridinium cation bound to the complex anion via N-H⋯S hydrogen bonding. The asymmetric unit consists of one Fe(III) cation, four thio-cyanate anions, two coordinated pyridine mol-ecules and one pyridinium cation. The structure exhibits π-π inter-actions between pyridine rings [centroid-centroid distances = 3.7267 (2), 3.7811 (2) and 3.8924 (2) Å]. The N atom and a neighboring C atom of the pyridinium cation are statistically disordered with an occupancy ratio of 0.58 (2):0.42 (2).

Tetra-kis(4-benzoyl-pyridine-κN)bis-(iso-thio-cyanato-κN)manganese(II).

Project description:The asymmetric unit of the title compound, [Mn(NCS)2(C12H9NO)4], consists of one MnII cation located on a centre of inversion, one thio-cyanate anion and two 4-benzoyl-pyridine co-ligands. The MnII cation is octa-hedrally coordinated by two terminally N-bonded anionic ligands and four N-bonded 4-benzoyl-pyridine co-ligands within a slightly distorted octa-hedron. Individual complexes are linked by inter-molecular C-H⋯O hydrogen-bonding inter-actions into chains running along the c-axis direction. Simultaneous thermogravimetry and differential scanning calorimetry measurements reveal a decomposition in two separate steps, in each of which two co-ligands are removed. The compound obtained after the first step has the composition [Mn(NCS)2(C12H9NO)2] and is of unknown structure, before in the second step decomposition into [Mn(NCS)2] is observed. Magnetic susceptibility measurements show the MnII cations to be in the high-spin state, and that weak anti-ferromagnetic inter-actions between the complexes are present.
