Bis(1,10-phenanthroline-?N,N')bis-(thio-cyanato-?N)cadmium.

ABSTRACT: The title compound, [Cd(NCS)(2)(C(12)H(8)N(2))(2)], has been obtained from the decomposition reaction of dithio-oxamide in a dimethyl-formamide solution containing 1,10-phenanthroline (phen) and Cd(NO(3))(2)·4H(2)O. Its crystal structure is formed by monuclear Cd(II) entities in which the metal atom is sited on a twofold rotation axis. The Cd(II) atom is six-coordinated in the form of a distorted octa-hedron by two chelating phenanthroline mol-ecules and two thio-cyanate anions coordinated through their N atoms. In the crystal, C-H?N hydrogen bonds are established between the phenanthroline and thio-cyanate ligands of neighbouring complexes.

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.

cis-Bis(1,10-phenanthroline-?N,N')bis-(thio-cyanato-?N)magnesium(II).

Project description:The title compound, [Mg(NCS)(2)(C(12)H(8)N(2))(2)], has been synthesized from the hydro-thermal reaction of MgCl(2), KSCN, 1,10-phenanthroline and H(2)O. Its structure is isotypic with the Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) analogues. The Mg(II) cation has a slightly distorted octa-hedral geometry containing four N atoms from two 1,10-phenanthroline mol-ecules and two N atoms from two thio-cyanate anions. The asymmetric unit contains one-half mol-ecule, and the complete complex has 2 symmetry.

[2,9-Bis(3,5-dimethyl-1H-pyrazol-1-yl-?N)-1,10-phenanthroline-?N,N']bis-(thio-cyanato-?N)cadmium(II).

Project description:In the title complex, [Cd(NCS)(2)(C(22)H(20)N(6))], the Cd(II) ion is in a CdN(6) coordination geometry which is inter-mediate between octa-hedral and trigonal-prismatic. The dihedral angles formed between the mean planes of the pyrazole rings and the phenanthroline system are 15.74?(15) and 16.30?(13)°. In the crystal, there is a ?-? stacking inter-action involving two symmetry-related pyrazole rings, with a centroid-centroid distance of 3.664?(3)?Å. In addition, there is a relatively short inter-molecular contact between C atoms [C?C = 3.399?(6)?Å] involving symmetry-related pyridine rings along the a axis.

(2,9-Dimethyl-1,10-phenanthroline-?(2)N,N')bis-(thio-cyanato-?S)mercury(II).

Project description:The asymmetric unit of the title compound, [Hg(SCN)(2)(C(14)H(12)N(2))], contains two complex mol-ecules in which the Hg(II) atoms are both four-coordinated in a distorted tetra-hedral configuration by two N atoms from a chelating 2,9-dimethyl-1,10-phenanthroline ligand and by two S atoms from two thio-cyanate anions. The 1,10-phenanthroline ligand is slightly folded for one complex, the dihedral angle between the pyridine planes being 5.3?(1)°. In contrast it is nearly planar [0.5?(1)°] as it complexes with the other Hg(II) atom. The thio-cyanate ligands are virtually linear and the S atom is bonded to Hg(II) with N?S-Hg angles ranging from 99.3?(1) to 103.5?(1)°. Despite the presence of six aromatic rings in the asymmetric unit, there are no significant inter-molecular ?-? contacts between phenanthroline ligands as the centroid-centroid distance of the closest contact between six-membered rings is 4.11?(1) A°.

Project description:In the title complex, [Co(NCS)(2)(C(16)H(16)N(2)O(2))], the Co(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline ligand and two N atoms from two different thio-cyanate ligands in a distorted tetra-hedral environment.
