[1-(5-Bromo-2-oxidobenzyl-idene)thio-semicarbazidato-κ(3)O,N(1),S](pyridine-κN)nickel(II).

ABSTRACT: The reaction of 5-bromo-salicyl-aldehyde thio-semicarbazone with nickel acetate tetra-hydrate and pyridine yielded the title compound, [Ni(C(8)H(6)BrN(3)OS)(C(5)H(5)N)]. The Ni(II) atom is four-coordinated in a square-planar environment by one deprotonated dianionic thio-semicarbazone ligand, acting in a tridentate chelating mode through N, O and S atoms forming two metalla-rings, and by one pyridine mol-ecule. The complex mol-ecules are linked into dimers by pairs of centrosym-metrical N-H⋯N inter-actions. In addition, mol-ecules are connected through inter-molecular Br⋯Br inter-actions [3.545 (1) Å], forming chains along the b-axis direction.

[1-(2-Oxidobenzyl-idene)-4-phenyl-thio-semicarbazidato-κO,N,S](pyridine-κN)copper(II).

Project description:In the structure of the title compound, [Cu(C(14)H(11)N(3)OS)(C(5)H(5)N)], the Cu(II) atom exhibits a slightly distorted square-planar CuN(2)OS coordination polyhedron consisting of a phenyl O, an azomethine N and a thio-amide S atom from the tridentate thio-semicarbazonate dianion, and the N atom of a pyridine mol-ecule. The thio-semicarbazonate ligand exists in the thiol tautomeric form as an E isomer. Rotational disorder of the pyridine and phenyl rings in a 1:1 ratio of the respective components is observed. An extensive network of weak N-H⋯S, C-H⋯O, C-H⋯N and C-H⋯S hydrogen-bonding inter-actions consolidates the structure.

Crystal structure of bis-(3-bromo-pyridine-κN)bis-(O-ethyl di-thio-carbonato-κ(2) S,S')nickel(II).

Project description:In the title mol-ecular complex, [Ni(C3H5OS2)2(C5H4BrN)2], the Ni(2+) cation is located on a centre of inversion and has a distorted octa-hedral N2S4 environment defined by two chelating xanthate ligands and two monodentate pyridine ligands. The C-S bond lengths of the thio-carboxyl-ate group are indicative of a delocalized bond and the O-Csp (2) bond is considerably shorter than the O-Csp (3) bond, consistent with a significant contribution of one resonance form of the xanthate anion that features a formal C=O+ unit and a negative charge on each of the S atoms. The packing of the mol-ecules is stabilized by C-H⋯S and C-H⋯π inter-actions. In addition, π-π inter-actions between the pyridine rings [centroid-to-centroid distance = 3.797 (3) Å] are also present. In the crystal structure, mol-ecules are arranged in rows along [100], forming layers parallel to (010) and (001).

Project description:In the title compound, [Ni(NCS)2(C5H5N)2] n , the Ni(2+) cation is coordinated by four thio-cyanate anions (μ-1,3) and two pyridine ligands within a slightly distorted octa-hedral configuration. The Ni-N bond lengths to the pyridine rings are 2.1189 (17) and 2.1241 (17) Å, whereas those to the thiocyanate anions are 2.0299 (18) and 2.0359 Å. The Ni-S bond lengths are 2.5357 (6) and 2.5568 (6) Å. The Ni(2+) cations are linked by N:S-bridging thio-cyanate ligands into chains extending along [010]. The Ni⋯Ni distance within the chains is 5.5820 (5) Å. The asymmetric unit contains two Ni(2+) cations of which one is located on a centre of inversion, whereas the second is located on a general position.

Project description:The central Ni(II) atom in the title complex, [Ni(C(16)H(13)BrN(2)O(2))(C(5)H(5)N)], is in a square-planar trans-N(2)O(2) environment defined by the NO(2) donor atoms of the tridentate hydrazone ligand and the monodentate pyridine ligand.

Bis[μ-N'-(2-oxidobenzyl-idene)thio-phene-2-carbohydrazidato]bis-[dimethanol-nickel(II)].

Project description:In the crystal structure of the centrosymmetric binuclear title complex, [Ni(2)(C(12)H(8)N(2)O(2)S)(2)(CH(3)OH)(4)], there are inter-molecular O-H⋯O, O-H⋯N and O-H⋯S hydrogen bonds. These help to stabilize the structure and link the mol-ecules, forming a three-dimensional network structure. The Ni(2+) cation exists in a slightly distorted octahedral NiNO(5) coordination environment. The thio-phene rings are disordered over two equivalent conformations with occupancies of 0.881 (3) and 0.119 (3).

Bis[μ-4-(2-oxidobenzyl-idene)thio-semi-carbazidato-κS,N,O:O]bis-[(pyridine-κN)zinc].

Project description:In the title compound, [Zn(2)(C(8)H(7)N(3)OS)(2)(C(5)H(5)N)(2)], the Zn(2)O(2) ring has a flattened roof shape, with the roof angle equal to 10.10 (6)°. The thio-semicarbazones act as tridentate ligands to one Zn(II) atom, with the O atoms additionally in bridging positions to the second Zn(II) atom. Both Zn(II) atoms are five-coordinated; the coordination polyhedra are close to square pyramids, with the pyridine N atoms at apical positions. Two inter-molecular N-H⋯N and one relatively weak N-H⋯S hydrogen bond, together with C-H⋯S weak inter-actions, connect the mol-ecules into a three-dimensional network.
