Bis[5-chloro-2-(phenyl-diazenyl-?N(2))pyridine-?N]bis-(thio-cyanato-?N)iron(II).

ABSTRACT: In the title complex, [Fe(NCS)(2)(C(11)H(8)ClN(3))(2)], the Fe(II) atom is coordinated by two N atoms from the thio-cyanate ligands and four N atoms from two chelating 5-chloro-2-(phenyl-diazen-yl)pyridine ligands, generating a fairly regular FeN(6) octa-hedral coordination geometry. The thio-cyanate ions are in a cis disposition and the pyridine N atoms are in a trans orientation. In the crystal, a short inter-molecular Cl?S contact [3.366?(3)?Å] is observed.

Project description:The crystal structure of the title Fe(II) complex, [Fe(NCS)(2)(C(7)H(8)N(4)S)(2)(CH(3)CH(2)OH)(2)]·2C(7)H(8)N(4)S, based on the Schiff base ligand pyridine-3-carbaldehyde thio-semicarbazone (pct), results from the cocrystallization of an Fe(II) coordination compound together with two of the pct ligands. The complex unit is mononuclear, with the central Fe(II) ion located on a crystallographic centre of inversion and coordinated by four N atoms from two pct ligands and two thio-cyanate anions. The slightly distorted octa-hedral coordination is completed by two O atoms from ethanol mol-ecules. The crystal packing is accomplished inter-molecular N-H?S hydrogen bonds.

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.

Weak inter-actions of types C-H?S and C-H?Cl consolidate the crystal packing.

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