Crystal structure and thermal properties of bis-[μ-2-(meth-oxy-carbonyl-hydrazinyl-idene)acetato-κ³ N ¹,O:O]bis-[di-aqua-(thio-cyanato-κN)manganese(II)] tetra-hydrate.

ABSTRACT: The title compound, [Mn₂(C₄H₅N₂O₄)₂(NCS)₂(H₂O)₄]·4H₂O (I), exists as a centrosymmetric dimer. Each dimeric unit consists of tridentate (O,O,N)-chelating Schiff bases with symmetry-maintained μ-O-bridged carboxyl-ate anions, terminally bound thio-cyanate anions, and ligated and solvated water mol-ecules. The complex exhibits a distorted octa-hedron geometry and the centrosymmetric μ-O-bridged carboxyl-ate anions connect the two manganese atoms to form an M ₂O₂ ring. In the crystal, the mol-ecules are inter-linked via strong N-H⋯O and O-H⋯O hydrogen-bonding contacts and weak O-H⋯S inter-molecular inter-actions, forming a three-dimensional mol-ecular network.

Crystal structure of aqua-tris-(isonicotinamide-κN)bis-(thio-cyanato-κN)cobalt(II) 2.5-hydrate.

Project description:The asymmetric unit of the title compound, [Co(NCS)2(C6H6N2O)3(H2O)]·2.5H2O, comprises one CoII cation, three isonicotinamide ligands, two thio-cyanate anions, one aqua ligand and two water solvent mol-ecules in general positions, as well as one water solvent mol-ecule that is located on a twofold rotation axis. The CoII cations are octa-hedrally coordinated by two terminally N-bonded thio-cyanate anions, one water mol-ecule and three isonicotinamide ligands, each coordinating via the pyridine N atom. The discrete complexes are linked by inter-molecular O-H⋯O, N-H⋯O and N-H⋯S hydrogen bonding into a three-dimensional network that contains cavities in which the solvent water mol-ecules are located. The latter are linked by further O-H⋯O hydrogen bonds to the network. There are additional short contacts present in the crystal, indicative of weak C-H⋯S, C-H⋯O and C-H⋯N inter-actions.

Project description:The asymmetric unit of the title compound, [Co(NCS)2(C6H6NS)4]·CH3OH, consists of one cobalt(II) cation, two thio-cyanate anions, four pyridine-4-carbo-thio-amide ligands and one methanol mol-ecule that are located in general positions.

These complexes are linked into a three-dimensional network via inter-molecular N-H⋯S hydrogen bonding between the amino H atoms and the thio-cyanate and pyridine-4-carbo-thio-amide S atoms. From this arrangement, channels are formed in which the methanol solvate mol-ecules are embedded and linked to the host structure by inter-molecular O-H⋯S and N-H⋯O hydrogen bonding.

Di-aqua-bis-(nicotinamide-κN (1))bis-(thio-cyanato-κN)nickel(II).

Project description:In the title complex, [Ni(NCS)2(C6H6N2O)2(H2O)2], the Ni(II) ion is located on an inversion center and is coordinated in a distorted octa-hedral environment by two N atoms from two nicotinamide ligands and two water mol-ecules in the equatorial plane, and two N atoms from two thio-cyanate anions in the axial positions, all acting as monodentate ligands. In the crystal, weak N-H⋯S hydrogen bonds between the amino groups and the thio-cyanate anions form an R 4 (2)(8) motif. The complex mol-ecules are linked by O-H⋯O, O-H⋯S, and N-H⋯S hydrogen bonds into a three-dimensional supra-molecular structure.

When the three longer Pb⋯S inter-actions are considered, the eight-coordinate geometry is based on a dodeca-hedron. The Pb(CH(3)COO)(2)(NCS)](-) anion has mirror symmetry. The potassium cations connect the other constituents into a three-dimensional network through electrostatic K⋯N and K⋯S inter-actions.

Project description:Reaction of Co(NCS)2 and Zn(NCS)2 with 4-pyridine-thio-amide led to the formation of compounds with composition [Co(NCS)2(C6H6N2S)4]·H2O (1) and [Zn(NCS)2(C6H6N2S)2] (2), respectively. The asymmetric unit of compound 1, consists of one cobalt(II) cation, two thio-cyanate anions, four 4-pyridine-thio-amide ligands and one water mol-ecule whereas that of compound 2 comprises one zinc(II) cation that is located on a twofold rotation axis as well as one thio-cyanate anion and one 4-pyridine-thio-amide ligand in general positions. In the structure of compound 1, the cobalt(II) cations are octa-hedrally coordinated by two terminal N-bonding thio-cyanate anions and by the N atoms of four 4-pyridine-thio-amide ligands, resulting in discrete and slightly distorted octa-hedral complexes. These complexes are linked into a three-dimensional network via inter-molecular N-H⋯S hydrogen bonding between the amino H atoms and the thio-cyanate S atoms. From this arrangement, channels are formed in which the water mol-ecules are embedded and linked to the host structure by inter-molecular O-H⋯S and N-H⋯O hydrogen bonding. In the structure of compound 2, the zinc(II) cations are tetra-hedrally coordinated by two N-bonding thio-cyanate anions and the N atoms of two 4-pyridine-thio-amide ligands into discrete complexes. These complexes are likewise connected into a three-dimensional network by inter-molecular N-H⋯S hydrogen bonding between the amino H atoms and the thio-amide S atoms.

Project description:The asymmetric unit of the title compound, [Fe(NCS)2(C6H4N2)2(H2O)2]·2C6H4N2, comprises one FeII cation occupying an inversion centre as well as one thio-cyanate anion, one water mol-ecule and two 4-cyano-pyridine mol-ecules in general positions.

The resulting coordination polyhedron can be described as a slightly distorted octa-hedron. The discrete complexes are connected through centrosymmetric pairs of (pyridine)C-H⋯N(cyano) hydrogen bonds into chains that are further linked into a three-dimensional network through inter-molecular O-H⋯N hydrogen bonds involving the 4-cyano-pyridine solvent mol-ecules.

Crystal structure of bis-(tetra-methyl-thio-urea-κS)bis-(thio-cyanato-κN)nickel(II).

Project description:In the course of our investigations regarding transition-metal thio-cyanates with thio-urea derivatives, the title compound, [Ni(NCS)2(C5H12N2S)2], was obtained. The asymmetric unit consists of one thio-cyanate anion and one tetra-methyl-thio-urea mol-ecule on general positions, as well as one NiII cation that is located on a twofold rotational axis. In this compound, discrete complexes are formed in which the NiII cations are surrounded by two trans-N-bonding thio-cyanate anions as well as two trans-S-bonding tetra-methyl-thio-urea mol-ecules within a distorted square-planar coordination geometry. The discrete complexes are linked by pairs of weak C-H⋯S hydrogen bonds between the thio-cyanate S and one of the tetra-methyl-thio-urea methyl hydrogen atoms into chains along the crystallographic a- and c-axis directions, which are combined into layers parallel to the ac plane. X-ray powder diffraction proves that a pure crystalline phase was obtained and measurements using thermogravimetry and differential thermoanalysis reveal that the compound decomposes at about 408 K, where all tetra-methyl-thio-urea mol-ecules are lost.
