Crystal structure of bis-(aceto-nitrile-?N)bis-(4-benzoyl-pyridine-?N)bis-(thio-cyanato-?N)cobalt(II).

ABSTRACT: The crystal structure of the title compound, [Co(NCS)₂(C₂H₃N)₂(C₁₂H₉NO)₂], consists of cobalt(II) cations that are octa-hedrally coordinated by the N atoms of two terminal thio-cyanate anions, two aceto-nitrile mol-ecules and two 4-benzoyl-pyridine ligands. The discrete complexes are located on centres of inversion. They are connected by weak inter-molecular C-H?O and C-H?S hydrogen-bonding inter-actions between one of the pyridine H atoms and the carbonyl O atom, and between one of the methyl H atoms of the aceto-nitrile mol-ecule and the thio-cyanate S atoms into layers parallel to (101). No pronounced inter-molecular inter-actions are observed between these layers.

Crystal structure, synthesis and thermal properties of bis-(aceto-nitrile-?N)bis-(4-benzoyl-pyridine-?N)bis-(iso-thio-cyanato-?N)nickel(II).

Project description:In the crystal structure of the title com-pound, [Ni(NCS)2(CH3CN)2(C12H9NO)2] or Ni(NCS)2(4-benzoyl-pyridine)2(aceto-nitrile)2, the NiII ions are octa-hedrally coordinated by the N atoms of two thio-cyanate anions, two 4-benzoyl-pyridine ligands and two aceto-nitrile mol-ecules into discrete com-plexes that are located on centres of inversion. In the crystal, the discrete com-plexes are linked by centrosymmetric pairs of weak C-H?S hydrogen bonds into chains. Thermogravimetric measurements prove that, upon heating, the title com-plex loses the two aceto-nitrile ligands and transforms into a new crystalline modification of the chain com-pound [Ni(NCS)2(4-benzoyl-pyridine)2], which is different from that of the corresponding CoII, NiII and CdII coordination polymers reported in the literature. IR spectroscopic investigations indicate the presence of bridging thio-cyanate anions but the powder pattern cannot be indexed and, therefore, this structure is unknown.

Crystal structure of bis-(4-benzoyl-pyridine-?N)bis-(methanol-?O)bis-(thio-cyanato-?N)cobalt(II).

Project description:The crystal structure of the title compound, [Co(NCS)2(C12H9NO)2(CH3OH)2], consists of cobalt(II) cations that are octa-hedrally coordinated by two N-terminal bonding thio-cyanato anions, two methanol mol-ecules and two 4-benzoyl-pyridine ligands into discrete complexes that are located on centres of inversion. These complexes are further linked by O-H?O hydrogen bonding between the hy-droxy H atom of the methanol ligand and the carbonyl O atom of the 4-benzoyl-pyridine ligand of a neighboring complex into layers parallel to (101). No pronounced inter-molecular inter-actions are observed between these layers.

Crystal structures of tetra-kis-(pyridine-4-thio-amide-?N)bis-(thio-cyanato-?N)cobalt(II) monohydrate and bis-(pyridine-4-thio-amide-?N)bis-(thio-cyanato-?N)zinc(II).

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:Reaction of Co(NCS)2 or Ni(NCS)2 with pyridine-4-thio-amide in different solvents led to the formation of two compounds with composition [Co(NCS)2(C2H3N)(C6H6N2S)3]·2CH3CN (1) and [Ni(NCS)2(C6H6N2S)4]·5CH3OH (2), respectively. The asymmetric unit of compound 1 consists of one cobalt(II) cation, two thio-cyanate anions, three pyridine-4-thio-amide ligands, one coordinating and two solvate aceto-nitrile mol-ecules. One of the two aceto-nitrile solvate mol-ecules is disordered over two sets of sites in a 0.62:0.38 ratio. The asymmetric unit of compound 2 comprises of one nickel(II) cation, two thio-cyanate anions, four N-bonding pyridine-4-thio-amide ligands and five methanol solvate mol-ecules. In compound 1, the cobalt(II) cations are octa-hedrally coordinated into discrete complexes by two terminal N-bonding thio-cyanate anions, the N atoms of three pyridine-4-thio-amide ligands and one aceto-nitrile mol-ecule. Additional aceto-nitrile solvate mol-ecules are located between the complexes,. The complexes and solvate mol-ecules are linked via inter-molecular hydrogen bonding into a three-dimensional framework. In compound 2, the nickel(II) cations are likewise octa-hedrally coordinated by two terminal N-bonded thio-cyanate anions and four N-bonding pyridine-4-thio-amide ligands into discrete complexes. From their arrangement cavities are formed, in which the methanol solvate mol-ecules are located. Again, the complexes and solvate mol-ecules are linked into a three-dimensional framework by inter-molecular hydrogen bonding.

Project description:The asymmetric unit of the title compound, [Fe(NCS)2(C12H9NO)4], consists of an FeII ion that is located on a centre of inversion, as well as two 4-benzoyl-pyridine ligands and one thio-cyanate anion in general positions. The FeII ions are coordinated by two N-terminal-bonded thio-cyanate anions and four 4-benzoyl-pyridine ligands into discrete complexes with a slightly distorted octa-hedral geometry. These complexes are further linked by weak C-H⋯O hydrogen bonds into chains running along the c-axis direction. Upon heating, this complex loses half of the 4-benzoyl-pyridine ligands and transforms into a compound with the composition Fe(NCS)2(4-benzoyl-pyridine)2, that might be isotypic to the corresponding MnII compound and for which the structure is unknown.

Crystal structure of bis-(2,2'-bi-pyridine-κ(2) N,N')bis-(thio-cyanato-κN)mang-anese(II) 2,2'-bi-pyridine monosolvate.

Project description:In the crystal structure of the mononuclear title compound, [Mn(NCS)2(C10H8N2)2]·C10H8N2, the Mn(II) cation is coordin-ated in an all-cis configuration by two N-bound thio-cyanate anions and two 2,2'-bi-pyridine ligands within a slightly distorted octa-hedral environment. The asymmetric unit consists of one Mn(II) cation, two thio-cyanate anions and two 2,2'-bi-pyridine ligands, as well as two non-coordinating 2,2'-bi-pyridine ligands that are each located on centres of inversion. In the crystal structure, the discrete [Mn(NCS)2(C10H8N2)2] complex mol-ecules are arranged in such a way that cavities are formed, in which the solvent 2,2'-bi-pyridine mol-ecules are located. Apart from van der Waals forces, there are no remarkable inter-molecular inter-actions present in the crystal structure.

Crystal structure of di-aqua-bis-(4-cyano-pyridine-κN)bis-(thio-cyanato-κN)iron(II) 4-cyano-pyridine disolvate.

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 iron cations are coordinated by two N-bonded thiocyanate anions, two (pyridine)N-bonded 4-cyano-pyridine ligands and two water mol-ecules into discrete complexes. 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-?S)bis(thio-cyanato-?N)cobalt(II).

Project description:In the course of systematic investigations on the synthesis of Co(NCS)2 coordination compounds with different thio-urea ligands, the title compound, [Co(NCS)2(C5H12N2S)2], was obtained. In this compound the CoII cations are coordinated by two crystallographically independent N-bonded thio-cyanate anions and two tetra-methyl-thio-urea ligands into discrete complexes that are located in general positions and show a strongly distorted tetra-hedral geometry. Inter-molecular C-H?S hydrogen bonds of different strength can be observed between the discrete complexes, which are connected by pairs of hydrogen bonds into zigzag-like chains that elongate in the b-axis direction. These chains are additionally linked by strong C-H?S hydrogen bonds along the a-axis direction, resulting in the formation of layers that are parallel to the ab plane. There is also one weak intra-molecular C-H?S hydrogen bond between two neighbouring thio-urea ligands within the complexes. Comparison of the experimental PXRD pattern with that calculated from the single-crystal data prove that a pure phase has been obtained. Thermoanalytical investigations reveal that this compound melts at 364?K and decomposes upon further heating.

Diammine(2,2'-bipyridine)-bis(thio-cyan-ato--?N)cobalt(III) diamminetetra-kis(thio-cyanato--?N)chromate(III) aceto-nitrile disolvate.

Project description:The new heterometallic title complex, [Co(NCS)(2)(C(10)H(8)N(2))(NH(3))(2)][Cr(NCS)(4)(NH(3))(2)]·2CH(3)CN, has been prepared using the open-air reaction of cobalt powder, Reineckes salt and 2,2'-bipyridine (dpy) in acetonitrile. The crystal structure consists of discrete cationic [Co(NCS)(2)(NH(3))(2)(dpy)](+) and anionic [Cr(NCS)(4)(NH(3))(2)](-) building blocks, both with 2 symmetry, and acetonitrile solvent mol-ecules, which are linked together by N-H?N hydrogen bonds, forming extended supra-molecular chains. Furthermore, N-H?S, C-H?S and C-H?N hydrogen bonds inter-link neighbouring chains into a three-dimensional framework. The Co atom is in an elongated octa-hedral coordination environment with two N atoms from the dpy ligands and two NCS-groups in the equatorial plane and with two NH(3) mol-ecules at the axial positions. The Cr(III) ion is octa-hedraly coordinated by two NH(3) mol-ecules at the axial positions and four NCS-groups in the equatorial plane. Intensity statistics indicated non-merohedral twinning with the twin matrix [100; 0[Formula: see text]0; [Formula: see text]0[Formula: see text]]. The refined ratio of the twin components is 0.530?(1):0.470?(1).
