(2,9-Dieth-oxy-1,10-phenanthroline-?N,N')bis-(thio-cyanato-?N)cobalt(II).

ABSTRACT: 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. The Co-N bonds involving the thio-cyanate ligands are significantly shorter than the other two Co-N bonds. The atoms of one of the eth-oxy groups are essentially coplanar with the phenanthroline ring [N=C-O-C = 178.8?(4)°], while the other eth-oxy group is slightly twisted from the phenanthroline ring plane [N=C-O-C = 167.2?(4)°]. In the crystal structure, there is a weak ?-? stacking inter-action between two symmetry-related phenanthroline rings with a centroid-centroid distance of 3.706?(4)?Å.

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.

(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°.
