Crystal structure of di-aqua-bis-(2-chloro-pyridine-?N)bis-(thio-cyanato-?N)nickel(II).

ABSTRACT: The asymmetric unit of the title compound, [Ni(NCS)₂(C₅H₄ClN)₂(H₂O)₂], consists of one nickel(II) cation that is located on a center of inversion and one thio-cyanate anion, one water mol-ecule and one 2-chloro-pyridine ligand all occupying general positions. The Ni^II cation is octa-hedrally coordinated by two terminal N-bound thio-cyanato ligands, two aqua ligands and two N-bound 2-chloro-pyridine ligands into discrete complexes. Individual complexes are linked by inter-molecular O-H?S and O-H?Cl hydrogen-bonding inter-actions into a layered network extending parallel to the bc plane. Weak inter-actions of types C-H?S and C-H?Cl consolidate the crystal packing.

Project description:In the title complex, [Ni(NCS)2(C6H6N2O)2(H2O)2], the Ni(II) ion is located on an inversion center and is coordinated in a distorted octa-hedral environment by two N atoms from two nicotinamide ligands and two water mol-ecules in the equatorial plane, and two N atoms from two thio-cyanate anions in the axial positions, all acting as monodentate ligands. In the crystal, weak N-H?S hydrogen bonds between the amino groups and the thio-cyanate anions form an R 4 (2)(8) motif. The complex mol-ecules are linked by O-H?O, O-H?S, and N-H?S hydrogen bonds into a three-dimensional supra-molecular structure. Weak ?-? inter-actions between the pyridine rings is also found [centroid-centroid distance = 3.8578?(14)?Å].

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.

Bis(di-2-pyridyl-amine-?N,N')bis-(thio-cyanato-?N)nickel(II).

Project description:The mononuclear neutral title complex, [Ni(NCS)(2)(C(10)H(9)N(3))(2)], shows a cis-octa-hedral geometry around the Ni(II) ion, formed by two chelating di-2-pyridyl-amine (Hdpa) ligands and two thio-cyanate anions. Both amine H atoms are involved in N-H?S hydrogen bonding, resulting in the formation of layers of inter-linked mol-ecules parallel to the ab plane, which are further held together by weak ?-? inter-actions between adjacent complexes, involving one ring of each dipyridyl-amine unit [centroid-centroid distance = 3.777?(4)?Å], forming a three-dimensional assembly.

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.

Di-μ-aqua-bis-[diaqua-bis(thio-cyanato-κN)iron(II)] 4-(4-chloro-phen-yl)-1,2,4-triazole hexa-solvate.

Project description:The title complex, [Fe(2)(NCS)(4)(H(2)O)(6)]·6C(8)H(6)ClN(3), comprises two distorted octa-hedral iron(II) centers straddling a crystallographic inversion center and bridged by two aqua O atoms to form a quadrilateral core. The aqua O atom of the core is involved in hydrogen bonds with the triazole N atoms of the solvent mol-ecules, generating one-dimensional ladder motifs, and three inter-molecular C-H⋯S hydrogen bonds, forming a three-dimensional hydrogen-bonding network.

Crystal structure of di-aqua-bis-(2,6-di-methyl-pyrazine-?N)bis-(thio-cyanato-?N)cobalt(II) 2,5-di-methyl-pyrazine tris-olvate.

Project description:In the crystal structure of the title compound, [Co(NCS)2(C6H8N2)2(H2O)2]·3C6H8N2, the Co(II) cation is coordinated by two terminally N-bound thio-cyanate anions, two water mol-ecules and two 2,6-di-methyl-pyrazine ligands, forming a discrete complex with a slightly distorted octa-hedral N4O2 coordination environment. The asymmetric unit contains one Co(II) cation and three halves of 2,5-di-methyl-pyrazine solvate mol-ecules, all entities being completed by inversion symmetry, as well as one thio-cyanate anion, an aqua ligand and a 2,6-di-methyl-pyrazine ligand, all in general positions. In the crystal, discrete complexes are arranged in a way that cavities are formed where the noncoordinating 2,5-di-methyl-pyrazine mol-ecules are located. The coordination of the latter to the metal is prevented due to the bulky methyl groups in vicinal positions to the N atoms, leading to a preferential coordination through the 2,6-di-methyl-pyrazine ligands. The complex mol-ecules are linked by O-H?N hydrogen bonds between the water H atoms and the N atoms of 2,5-di-methyl-pyrazine solvent mol-ecules, leading to a layered structure extending parallel to (100).

Crystal structure of poly[[(2,2'-bi-pyridine)manganese(II)]-di-?-thio-cyanato].

Project description:In the crystal structure of the polymeric title compound, [Mn(NCS)2(C10H8N2)] n , the Mn(II) cations are coordinated by one chelating 2,2'-bi-pyridine ligand and four thio-cyanate anions (two N- and two S-coordinating), forming a distorted [MnN4S2] octa-hedron. The asymmetric unit consists of one manganese cation located on a twofold rotation axis and half of a 2,2'-bi-pyridine ligand, the other half being generated by the same twofold rotation axis, as well as one thio-cyanate anion in a general position. The Mn(II) cations are linked by two pairs of ?1,3-bridging thio-cyanate ligands into chains along the c axis; because the N atoms of the 2,2'-bi-pyridine ligands, as well as the N and the S atoms of the thio-cyanate anions, are each cis-coordinating, these chains show a zigzag arrangement.
