In the title crystal structure, [Cd(NCS)(NO(3))(C(11)H(9)N(5))](n), the unique Cd(II) ion is coordinated in a distorted penta-gonal-bipyramidal environment. The axial thio-cyanate ligands act in a μ(1,3)-bridging mode to connect symmetry-related Cd(II) ions into one-dimensional chains along [010]. In addition, there are inter-molecular C-H⋯O contacts between chains.
Formation of cyanates in low-valent uranium chemistry: a synergistic experimental/theoretical study.
Computational studies on the reductive activation of a mixture of CO and NO by the U(iii) complex [U(η-C8H6{Si(i)Pr3-1,4}2)(η-Cp*)], which affords a mixture of [U(η-C8H6{Si(i)Pr3-1,4}2)(η-Cp*)]2(μ-OCN)21 and [U(η-C8H6{Si(i)Pr3-1,4}2)(η-Cp*)]2(μ-O) 2, show that the reaction proceeds via an initial attack of CO on a μ-η(2):η(2) coordinated NO, side-on bridged between two uranium centres. This lea...
In the title complex, [Cu(NCS)(C(12)H(8)N(2))](n), the Cu(I) ion is in a distorted tetra-hedral CuN(3)S coordination geometry. The thio-cyanate ligand acts as bridging ligand, forming chains along [100]. A crystallographic mirror plane runs through the Cu(I) ion, the thio-cyanate ligand and the middle of the phenanthroline ligand.
In the mononuclear title complex, [Co(NCS)(2)(C(9)H(10)N(2)O)(2)]·CH(3)OH, the cobalt(II) ion is surrounded by two (1-methyl-1H-benzimidazol-2-yl)methanol bidentate ligands and two thio-cyanate ligands, and exhibits a distorted octa-hedral coordination by four N atoms and two O atoms. The structure is consolidated by hydrogen bonds between the organic ligand, thio-cyanate anion and the uncoordi...
A homochiral helical coordination polymer of copper(II) has been synthesized using achiral precursors via spontaneous symmetry breaking and has been confirmed by single crystal X-ray diffraction and solid-state CD spectroscopy. The variable temperature magnetic measurements indicate the presence of weak ferromagnetic exchange interactions mediated by end-to-end cyanate bridges (J = +0.12 cm(-1)).
In the title complex, [Co(NCS)(2)(C(13)H(19)N(3)O)(H(2)O)], the Co(II) ion is six-coordinated by the N,N',N''-tridentate Schiff base, the N atoms of two thio-cyanate ligands and one water mol-ecule in a distorted octa-hedral geometry. Intra-molecular C-H⋯N and C-H⋯O hydrogen bonds occur. In the crystal, inter-molecular O-H⋯O, O-H⋯S, C-H⋯S and S⋯S [3.5546 (18) Å] inter-actions result in an infin...
In the title compound, [Cd(NCS)(2)(C(7)H(7)NO)](n), the Cd(2+) ion is six-coordinated by one N,O-bidentate 1-(2-pyridyletahanone ligand, two N-bonded thio-cyanate ions and two S-bonded thio-cyanate ions. In the resulting distorted CdOS(2)N(3) octa-hedron, the N atoms adopt a fac arrangement. The bridging thio-cyanate ions lead to infinite sheets oriented parallel to (101) in the crystal structure.
The structure of the title compound, [Cd(NCS)2(C7H9NO)2] n , consists of cadmium-thio-cyanate layers parallel to the ab plane. Pairs of Cd(II) ions are bridged by two end-to-end inversely bridging μ-NCS-N:S thio-cyanate groups, forming a two-dimensional network with the remaining two trans positions of the octa-hedrally coordinated Cd(II) ions occupied by the N atoms of two neutral 2-meth-oxy-a...
The Zn(II) ion in the title complex, [Zn(NCS)(2)(C(7)H(6)N(2)S)(2)], is tetra-hedrally coordinated within an N(4) donor set defined by two N atoms of two terminal isothio-cyanate ligands and by two heterocyclic N atoms of two different 2-amino-benzothia-zole ligands. This arrangement is stabilized by intra-molecular N-H⋯N hydrogen bonds. In the crystal structure, mol-ecules are linked through N...
In the binuclear centrosymmetric title compound, [Ag(2)(NCS)(2)(C(21)H(21)P)(4)]·0.35H(2)O, a pseudo-polymorph of [Ag(2)(NCS)(2)(C(21)H(21)P)(4)]·2CH(3)CN, the Ag atom is coordinated by two phosphine ligands and two bridging thio-cyanate ligands in a distorted tetra-hedral configuration. The crystal structure exhibits inter-molecular C-H⋯π inter-actions.
