Synthesis, crystal structure and thermal properties of poly[bis-[μ-3-(amino-meth-yl)pyridine-κ² N:N']bis(thio-cyanato-κN)manganese(II)].

ABSTRACT: The reaction of Mn(NCS)₂ with a stoichiometric amount of 3-(amino-meth-yl)pyridine in ethanol led to the formation of the title compound, [Mn(NCS)₂(C₆H₈N₂)₂] _n , which is isotypic to its Zn, Co and Cd analogues. The manganese cation is located on a centre of inversion and is octa-hedrally coordinated in an all-trans configuration by two terminal N-bonded thio-cyanate anions as well as four 3-(amino-meth-yl)pyridine co-ligands, of which two coordinate with the pyridine N atom and two with the amino N atom. The 3-(amino-meth-yl)pyridine co-ligands connect the Mn^II cations into layers extending parallel to (10). These layers are further connected into a three-dimensional network by relatively strong inter-molecular N-H⋯S hydrogen bonding. Comparison of the experimental X-ray powder diffraction pattern with the calculated pattern on the basis of single-crystal data proves the formation of a pure crystalline phase. IR measurements showed the CN stretching vibration of the thio-cyanate anions at 2067 cm^-1, which is in agreement with the presence of terminally N-bonded anionic ligands. TG-DTA measurements revealed that the title compound decomposes at about 500 K.

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.

Project description: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.

Synthesis, crystal structure and thermal properties of poly[bis-[μ2-3-(amino-meth-yl)pyridine]-bis-(thio-cyanato)-cobalt(II)].

Project description:The reaction of Co(NCS)2 with 3-(amino-meth-yl)pyridine as coligand leads to the formation of crystals of the title compound, [Co(NCS)2(C6H8N2)2] n , that were characterized by single-crystal X-ray analysis. In the crystal structure, the CoII cations are octa-hedrally coordinated by two terminal N-bonded thio-cyanate anions as well as two pyridine and two amino N atoms of four symmetry-equivalent 3-(amino-meth-yl)pyridine coligands with all pairs of equivalent atoms in a trans position. The CoII cations are linked by the 3-(amino-meth-yl)pyridine coligands into layers parallel to the ac plane. These layers are further linked by inter-molecular N-H⋯S hydrogen bonding into a three-dimensional network. The purity of the title compound was determined by X-ray powder diffraction and its thermal behavior was investigated by differential scanning calorimetry and thermogravimetry.

Project description:In the title one-dimensional coordination polymer, [Mn(NCS)(3)(C(10)H(16)N(3))](n), the Mn(II) atom is coordinated by an N,N'-bidentate Schiff base and four thio-cyanate ligands in a distorted octa-hedral N(5)S geometry. Bridging thio-cyanate ligands inter-connect adjacent [Mn(NCS)(2)(C(10)H(16)N(3))] units, giving rise to helical chains extending along the b axis. The chains are further linked through N-H?S hydrogen bonds, leading to a three-dimensional supra-molecular network.

Inter-molecular N-H?N and N-H?S hydrogen bonds link the copper complex mol-ecules into an infinite two-dimensional network.

Project description:The asymmetric unit of the title compound [Mn(NCS)(2)(C(9)H(13)N)(4)] consists of one Mn(II) cation located on a center of inversion, one thio-cyanato anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.60:0.40 ratio.

Bis{μ-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}bis-[(thio-cyanato)manganese(III)].

Project description:The reported structure is a monoclinic polymorph of the title compound, [Mn(2)(C(16)H(14)N(2)O(2))(2)(NCS)(2)], which has been characterized previously in an ortho-rhom-bic form. Each Mn(III) atom is chelated by a tetra-dentate 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate ligand and by the N atom of a thio-cyanate anion, in a square-pyramidal arrangement. The complexes form centrosymmetric dimers, with an Mn-O contact of 2.557 (3) Å trans to each thio-cyanate anion, completing a distorted octa-hedral coordination geometry.

Synthesis, crystal structure and thermal properties of bis-(aceto-nitrile-κN)bis-(3-bromo-pyridine-κN)bis-(thio-cyanato-κN)cobalt(II).

Project description:Single crystals of the title compound, [Co(NCS)2(C5H4BrN)2(C2H3N)2], were obtained by the reaction of Co(NCS)2 with 3-bromo-pyridine in aceto-nitrile. The CoII cations lie on crystallographic inversion centers and are coordinated by two N-bonded thio-cyanate anions, two 3-bromo-pyridine and two aceto-nitrile ligands thereby forming slightly distorted CoN6 octa-hedra. In the crystal, these complexes are linked by C-H⋯S and C-H⋯N hydrogen bonds into a three-dimensional network. In the direction of the crystallographic b-axis, the complexes are arranged into columns with neighboring 3-bromo-pyridine ligands stacked onto each other, indicating π-π inter-actions. The CN stretching vibration of the thio-cyanate anions is observed at 2066 cm-1, in agreement with the presence of only N-bonded anionic ligands. TG-DTA measurements reveal that in the first mass loss the aceto-nitrile ligands are removed and that in the second step, half of a 3-bromo-pyridine ligand is lost, leading to the formation of a polymeric compound with the composition [(Co(NCS)2)2(C5H4BrN)3] n already reported in the literature.

Bis(acetyl-acetonato-κ(2) O,O')(pyridine-κN)(thio-cyanato-κN)manganese(III): a redetermination using data from a single crystal.

Project description:In the crystal structure of the title compound, [Mn(C5H7O2)2(NCS)(C5H5N)], the Mn(3+) cation is coordin-ated by two acetyl-acetonate anions, one terminal thio-cyanate anion and one pyridine ligand within a slightly distorted octa-hedron. The asymmetric unit consists of half a complex mol-ecule with the Mn(3+) cation, the thio-cyanate anion and the pyridine ligand located on a mirror plane. The acetyl-acetonate 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.

Synthesis, crystal structure and thermal properties of tetra-kis-(3-methyl-pyridine-κN)bis-(thio-cyanato-κN)nickel(II).

Project description:Reaction of Ni(NCS)2 with 3-methyl-pyridine in water leads to the formation of crystals of the title compound, [Ni(NCS)2(C6H7N)4]. All of them are of poor quality and non-merohedrally twinned but a refinement using data in HKLF-5 format leads to a reasonable structure model and reliability factors. The crystal structure of the title compound consists of discrete complexes, in which the nickel cations are sixfold coordinated by two terminal N-bonded thio-cyanate anions and four 3-methyl-pyridine ligands within slightly distorted octa-hedra. One of the 3-methyl-pyridine ligands is disordered and was refined using a split model. The discrete complexes are arranged into layers. X-ray powder diffraction proves that pure samples have been obtained, and in the IR spectrum, the CN stretching vibration is observed at 2072 cm-1, in agreement with the presence of only terminally coordinated thio-cyanate anions. Comparing the calculated powder pattern with those of the residues obtained by solvent removal from several solvates already reported in the literature proves that, in each case, this crystalline phase is formed. Assessing the crystal structures of the solvates in comparison with that of the ansolvate reveals some similarities.
