Dichlorido(2,9-dimethyl-1,10-phenanthroline-?N,N')cobalt(II).

ABSTRACT: In the title compound, [CoCl(2)(C(14)H(12)N(2))], the Co(II) atom is four-coordinated in a distorted tetra-hedral geometry by two N atoms from a 2,9-dimethyl-1,10-phenanthroline ligand and two Cl atoms. The Co atom and the phenanthroline unit are located on a mirror plane. The methyl H atoms are disordered about the mirror plane and areeach half-occupied. In the crystal structure, ?-? inter-actions between the pyridine and benzene rings and between the pyridine rings [centroid-centroid distances = 3.8821?(9) and 3.9502?(10)?Å, respectively] stabilize the structure.

Dichlorido(2,9-dimethyl-1,10-phenanthroline-κ(2)N,N')mercury(II).

Project description:The title compound, [HgCl(2)(C(14)H(12)N(2))], consists of one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand chelating the Hg(II) ion and two chloride ligands coordinating to the Hg(II) ion, forming a distorted tetra-hedral environment.

(2,9-Dimethyl-1,10-phenanthroline-κN,N')bis-(2-hydroxy-benzoato)-κO;κO,O'-cobalt(II).

Project description:In the title compound, [Co(C(7)H(5)O(3))(2)(C(14)H(12)N(2))], the Co(II) ion is five-coordinated by two N atoms from one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and three O atoms from two 2-hydroxy-benzoate anions in a distorted trigonal bipyramidal geometry. The carboxyl-ate group of one of the two 2-hydroxy-benzoate anions is monodentate with a normal Co-O distance [1.9804 (18) Å], while the other is bidentate with two longer Co-O bonds [2.1981 (18) and 2.1359 (19) Å]. The crystal structure is stabilized by aromatic π-π stacking inter-actions [centroid-centroid distances of 4.0380 (3) and 3.8216 (3) Å between dmphen/dmphen and benzene/dmphen rings, respectively] and C-H⋯π(benzene) inter-actions.

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

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.

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 π-π stacking inter-action between two symmetry-related phenanthroline rings with a centroid-centroid distance of 3.706 (4) Å.

Project description:The asymmetric unit of the title compound, [HgCl(2)(C(26)H(20)N(2))]·0.5CH(3)CN, contains two crystallographic-ally independent [HgCl(2)(C(26)H(20)N(2))] mol-ecules and one acetonitrile solvent mol-ecule.
