(Piperazin-1-ium-?N)tris-(thio-cyanato-?N)zinc(II).

ABSTRACT: Hydro-thermal reaction of NaSCN, piperazine, Zn(II) and 2,6-naphthalenedicarboxylic acid in aqueous solutions gave rise to the title complex, [Zn(NCS)(3)(C(4)H(11)N(2))]. The Zn(II) atom is four-coordinate with distorted tetra-hedral geometry and lies in a mirror plane. N-H?S hydrogen bonds assemble the mol-ecules to form a three-dimensional framework.

Bis(2-chloro-1,10-phenanthroline-κN,N')(thio-cyanato-κN)zinc (2-chloro-1,10-phenanthroline-κN,N')tris-(thio-cyanato-κN)zincate.

Project description:The asymmetric unit of the title compound, [Zn(NCS)(C(12)H(7)ClN(2))(2)][Zn(NCS)(3)(C(12)H(7)ClN(2))], contains two cations and two anions. In the cations, the Zn(II) ions have distorted trigonal-bipyramidal environments formed by four N atoms from two 2-chloro-1,10-phenanthroline (cphen) ligands and one N atom from a thio-cyanate ligand. The Zn(II) atoms in the complex anions also have distorted trigonal-bipyramidal environments, formed by two N atoms from a cphen ligand and three N atoms from three thio-cyanato ligands. The crystal packing exhibits π-π inter-actions between the rings of the cphen ligands [shortest centroid-centroid distance = 3.586 (5) Å] and short inter-molecular S⋯Cl [3.395 (5) Å] and S⋯S [3.440 (4) Å] contacts.

Crystal structures of tetra-kis-(pyridine-4-thio-amide-κN)bis-(thio-cyanato-κN)cobalt(II) monohydrate and bis-(pyridine-4-thio-amide-κN)bis-(thio-cyanato-κN)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.

This arrangement is stabilized by intra-molecular N-H⋯N hydrogen bonds. In the crystal structure, mol-ecules are linked through N-H⋯S hydrogen bonds to form a two-dimensional array.

Project description:The title salt, (C₈H₂₀N)[Ni(NCS)₃(C₁₀H₁₀N₆)], consists of a tetra-ethyl-ammonium cation and an anion comprising an octa-hedral Ni(II) atom surrounded by three N atoms from a tripodal tris-(pyrazol-1-yl)methane ligand, and three thio-cyanate ligands, each bound at the N-atom end.

Project description:In the crystal structure of the title compound, [Ni(2)(NCS)(4)(C(4)H(4)N(2))(3)(CH(3)OH)(2)](n), each nickel(II) cation is coordinated by three N-bonded pyrimidine ligands, two N-bonded thio-cyanate anions and one O-bonded methanol mol-ecule in a distorted octa-hedral environment.

The layers are connected via weak O-H⋯S hydrogen bonding.
