Crystal structure of bis-(azido-?N)bis[2,5-bis(pyridin-2-yl)-1,3,4-thia-diazole-?(2) N (2),N (3)]cobalt(II).

ABSTRACT: In the mononuclear title complex, [Co(N3)2(C12H8N4S)2], the cobalt(II) atom is located on an inversion centre and displays an axially weakly compressed octa-hedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligands, whereas the axial positions are occupied by N atoms of the azide anions. The thia-diazole and pyridine rings linked to the metal are almost coplanar, with a maximum deviation from the mean plane of 0.0273?(16)?Å. The cohesion of the crystal is ensured by weak C-H?N hydrogen bonds and by ?-? inter-actions between pyridine rings [inter-centroid distance = 3.6356?(11)?Å], forming a layered arrangement parallel to (001). The structure of the title compound is isotypic with that of the analogous nickel(II) complex [Laachir et al. (2013 ?). Acta Cryst. E69, m351-m352].

trans-Diaqua-bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole]cobalt(II) bis-(tetra-fluoridoborate).

Project description:The bidentate 1,3,4-thia-diazole ligand substituted by two 2-pyridyl rings (denoted L) has been found to produce the new monomeric title complex, [Co(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The thia-diazole and pyridyl rings surrounding the Co atom are almost coplanar [dihedral angle = 4.35?(7)°]. The mean plane defined by these heterocyclic moieties makes a dihedral angle of 18.72?(6)° with the non-coordinated pyridyl ring. The Co(2+) cation, located at a crystallographic center of symmetry, is bonded to two ligands and two water mol-ecules in a trans configuration in an octa-hedral environment. The tetra-fluorido--borate ions can be regarded as free anions in the crystal lattice. Nevertheless, they are involved in an infinite two-dimensional network along the [010] and [101] directions of O-H?F hydrogen bonds.

Crystal structure of bis-(azido-?N)bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-?(2) N (2),N (3)]nickel(II).

Project description:Reaction of 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole and sodium azide with nickel(II) triflate yielded the mononuclear title complex, [Ni(N3)2(C12H8N4S)2]. The Ni(II) ion is located on a centre of symmetry and is octa-hedrally coordinated by four N atoms of the two bidentate heterocyclic ligands in the equatorial plane. The axial positions are occupied by the N atoms of two almost linear azide ions [N-N-N = 178.8?(2)°]. The thia-diazole and pyridine rings of the heterocyclic ligand are almost coplanar, with a maximum deviation from the mean plane of 0.0802?(9)?Å. The cohesion of the crystal structure is ensured by ?-? inter-actions between parallel pyridine rings of neighbouring mol-ecules [centroid-to-centroid distance = 3.6413?(14)?Å], leading to a layered arrangement of the mol-ecules parallel to (001).

trans-Diaqua-bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole]nickel(II) bis-(tetra-fluoridoborate).

Project description:The bidentate 1,3,4-thia-diazole ligand, namely, 2,5-bis-(2-pyrid-yl)-1,3,4-thia-diazole (denoted L), untested as a polydentate ligand, has been found to form the monomeric title complex, [Ni(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The complex shows an octa-hedral environment of the nickel cation in which the Ni(2+) ion is located on a center of symmetry, linked to two ligands and two water molecules. In this 1:2 complex (one metal for two organic ligands) each thia-diazole ligand uses one pyridyl and one thia-diazole N atom for chelate binding. In the second pyridyl substituent, the N atom is oriented towards the same direction as the S atom of the 1,3,4-thiadiazole ring. The mean plane of the thia-diazole and pyridyl rings linked to the nickel cation forms a dihedral angle with the other pyridine ring of 18.63?(8)°. The tetra-fluorido-borate ions can be regarded as free anions in the crystal lattice. Nevertheless, they are involved in an infinite two-dimensional network parallel to ([Formula: see text]01) through O-H?F hydrogen bonds.

trans-Bis[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-?(2) N (2),N (3)]bis-(methanol-?O)iron(II) bis-(perchlorate).

Project description:The title compound, [Fe(C12H8N4S)2(CH3OH)2](ClO4)2, crystallized in the solvent-free form from a methanol solution. The Fe(II) ion is located on a centre of inversion. The distorted N4O2 octa-hedral coordination geometry is formed by two N,N'-chelating equatorial 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligands and axially coordinating methanol coligands, resulting in the mononuclear trans-(N (2),N (3),O)2 coordination mode. The methanol co-ligand is involved in a hydrogen bond to the perchlorate counter-ion.

Crystal structure of bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-?(2) N (2),N (3)]bis-(thio-cyanato-?S)copper(II).

Project description:The mononuclear title complex, [Cu(SCN)2(C12H8N4S)2], was obtained by the reaction of 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole and potassium thio-cyanate with copper(II) chloride dihydrate. The copper cation lies on an inversion centre and displays an elongated octa-hedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligands, whereas the axial positions are occupied by the S atoms of two thio-cyanate anions. The thia-diazole and the pyridyl rings linked to the metal are approximately coplanar, with a maximum deviation from the mean plane of 0.190?(2)?Å. The cohesion of the crystal structure is ensured by weak C-H?N hydrogen bonds and ?-? inter-actions between parallel pyridyl rings of neighbouring mol-ecules [centroid-to-centroid distance = 3.663?(2)?Å], leading to a three-dimensional network.

Aqua-bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-?(2)N(2),N(3)](trifluoro-methane-sulfonato-?O)copper(II) trifluoro-methane-sulfonate.

Project description:2,5-Bis(pyridin-2-yl)-1,3,4-thia-diazole (denoted L) has been found to act as a bidentate ligand in the monomeric title complex, [Cu(CF(3)O(3)S)(C(12)H(8)N(4)S)(2)(H(2)O)](CF(3)O(3)S). The complex shows a distorted octahedrally coordinated copper(II) cation which is linked to two thia-diazole ligands, one water mol-ecule and one trifluoro-methane-sulfonate anion. The second trifluoro-methane-sulfonate anion does not coordinate the copper(II) cation. Each thia-diazole ligand uses one pyridyl and one thia-diazole N atom for the coordination of copper. The N atom of the second non-coordinating pyridyl substituent is found on the same side of the 1,3,4-thia-diazole ring as the S atom. The trifluoro-methane-sulfonate ions are involved in a three-dimensional network of O-H?O hydrogen bonds. C-H?N inter-actions also occur.

One aceto-nitrile group is above the plane of the 1,3,4-thia-diazole ring and the other is below it, indicating syn and anti orientations. In the crystal, C-H⋯N hydrogen bonds link the molecules into ribbons along [010].

Diaqua-(2,5-di-4-pyridyl-1,3,4-thia-diazole-?N)bis-(thio-cyanato-?N)nickel(II) dihydrate.

Project description:In the title mononuclear complex, [Ni(NCS)(2)(C(12)H(8)N(4)S)(2)(H(2)O)(2)]·2H(2)O, the Ni(II) atom is located on an inversion center and is octa-hedrally coordinated by four N atoms from two 2,5-di-4-pyridyl-1,3,4-thia-diazole (bpt) ligands and two thio-cyanate mol-ecules forming the equatorial plane; the axial positions are occupied by two O atoms of coordinated water mol-ecules. O-H?O, O-H?N and O-H?S hydrogen bonds, involving the uncoordinated water molecules, result in the formation of a sheet structure developing parallel to (021).
