Crystal structure of bis-[4-(4-chloro-benz-yl)pyridine-?N]bis-(thio-cyanato-?N)zinc.

ABSTRACT: In the crystal structure of the title compound, [Zn(NCS)2(C12H10ClN)2], the Zn(2+) cation is N-coordinated by two terminally bonded thio-cyante anions and by two 4-(4-chloro-benz-yl)pyridine ligands within a slightly distorted tetra-hedron. The asymmetric unit consists of half of the discrete complex, the central Zn(2+) cation of which is located on a twofold rotation axis. The discrete complexes are linked into layers via a weak inter-molecular hydrogen-bonding inter-action, with a H?Cl distance of 2.85?Å and a C-H?Cl angle of 151°. These layers extend parallel to the ab plane and are held together by dispersion forces only.

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.

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.

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.

The mol-ecular structure is stabilized by an intra-molecular N-H?S hydrogen bond, which forms an S(6) ring motif. In the crystal, mol-ecules are linked by a number of N-H?N and N-H?S hydrogen bonds, forming a three-dimensional framework. The first report of the crystal structure of this compound appeared in 1966 [Korczynski (1966 ?). Rocz. Chem. 40, 547-569] with an extremely high R factor of 17.2%, and no mention of how the data were collected.
