Hexakis(thiourea-κS)nickel(II) nitrate: a redetermination
نویسندگان
چکیده
A preliminary X-ray study of the title mol-ecular salt, [Ni(CH(4)N(2)S)(6)](NO(3))(2), has been reported twice previously, by Maďar [Acta Cryst. (1961), 14, 894] and Rodriguez, Cubero, Vega, Morente & Vazquez [Acta Cryst. (1961), 14, 1101], using film methods. We confirm the previous studies, but to modern standards of precision and with all H atoms located. The central Ni atom (site symmetry ) of the dication is octa-hedrally coordinated by six S-bound thio-urea mol-ecules. The crystal structure is stabilized by intra- and inter-molecular N-H⋯S and N-H⋯O hydrogen bonds.

The title complex salt, [Ni(C(3)H(8)N(2)S)(6)](NO(3))(2), consists of an [Ni(Dmtu)(6)](2+) (Dmtu is N,N'-dimethyl-thio-urea) dication and two nitrate counter-anions. The Ni(II) atom (site symmetry ) is coordinated by the S atoms of six Dmtu ligands within a slightly distorted octa-hedral environment. The crystal structure is characterized by weak intra-molecular N-H⋯S inter-actions and by inter...

In the title complex, [Ni(C(6)H(7)N(2)S)(2)(CH(4)N(2)S)(2)], the central Ni atom (located on a centre of inversion) is six-coordinated by two monoanionic N,S-chelating 4,6-dimethyl-pyrimidine-2-thiol-ate ligands and two trans S-coordinating thio-urea groups. The trans-N(2)S(4) donor set defines a distorted octa-hedral geometry.

The structure of the polymeric title compound, [CuCl(CH(4)N(2)S)(2)](n), has been redetermined to modern standards of precision with anisotropic refinement and location of the H atoms. The previous structure report [Spofford & Amma (1970 ▶). Acta Cryst. B26, 1474-1483] is generally confirmed to higher precision [typical Cu-S bond length s.u. values = 0.005 (old) and 0.001 Å (new)]. The asymmetr...

The title complex, [NiCl(2)(CH(4)N(2)S)(2)], has been synthesized from the previously reported (diamino-methyl-idene)sulfonium chloride-thio-urea (3/2) salt [Zouihri (2012b ▶). Acta Cryst. E68, o257]. The Ni(II) ion is coordinated in a distorted tetra-hedral geometry by two mol-ecules of thio-urea [Ni-S = 2.3079 (7) and 2.3177 (6) Å] and two chloride anions [Ni-Cl = 2.2516 (7) and 2.2726 (7) Å]...

The title compound, [Cd(CH(4)N(2)S)(2)(H(2)O)(4)][Cd(CH(4)N(2)S)(3)(H(2)O)(3)](SO(4))(2), contains two mol-ecules of each of the Cd complexes and four sulfate ions in the asymmetric unit: all the Cd atoms exhibit distorted octa-hedral geometries. The Cd-S and Cd-O bond lengths around the Cd atoms in the bis-(thio-urea) cations are in the ranges 2.580 (4)-2.599 (4) and 2.323 (8)-2.421 (9) Å, res...
